The rationality of rage
Anger is a primal and destructive emotion , disrupting rational discourse and inflaming illogical passions - or so it often seems. Then again , anger also has its upsides. Expressing anger, for example, is known to be a useful tool in negotiations . Indeed , in the past few years, researchers have been learning more about when and how to deploy anger productively.
Consider a forthcoming paper in the November issue of the Journal of Experimental Social Psychology. Researchers tested the effectiveness of expressing anger in three types of negotiations; those that are chiefly cooperative (say, starting a business with a partner), chiefly competitive (dissolving a shared business ) or balanced between the two (selling a business to a buyer). In two experiments, negotiators made greater concessions to those who expressed anger -but only in balanced situations . When cooperating , hostility seems inappropriate, and when competing , additional heat only flares tempers. But in between , anger appears to send a strategically useful signal.
What does that signal communicate ? According to a 2009 paper in Proceeding of the National Academy of Sciences, anger evolved to help us express that we feel undervalued . Showing anger signals to others that if we don't get our due, we'll expert harm or withhold benefits. As they anticipated , the researchers found that strong men and attractive women- those who have historically had the most leverage in threatening harm and conferring benefits, respectively - were most prone to anger.
The usefulness of angering extracting better treatment from others seems to be something we all implicitly understand. A 2013 paper in the journal Cognition and Emotion found that when people were preparing to enter a confrontational negotiation , as opposed to a cooperative one, they took steps to induce anger in themselves (choosing music, foe example).
The study also found that people induced anger in themselves only if there was an actual benefit at stake for them in the negotiation. This qualifications was essential in demonstrating that it was the perceived strategic benefit of being angry (and not, say, just a reflex that we have when entering any confrontation ) that prompted people to induce such an unpleasant mood in themselves.
Whether induced or not, anger must ultimately be genuine in order to be useful in provoking concessions. According to a 2013 paper in the Journal of Experimental Social Psychology, faking , anger, compared with playing it cool ,leads a negotiation partner to see you as less trustworthy, and actually increases his demands on you.
There are other important caveats. While expressions of anger can elicit compromises, they can also lead to covert retaliation, according to a 2012 paper in Organizational Behaviour and Human decision Processes. In two experiments, negotiators overtly made concessions when opponents expressed anger but, evidently feeling mistreated, covertly sabotaged their opponents afterward. Outside the laboratory, this dynamic might take the form of acquiescing to an angry colleague's demand but then spreading negative gossip about him around the office.
Anger also works better in negotiations when it's directed at an offer rather than at the person making the offer, according to a 2011 article in the Journal of Experimental Social Psychology. Many of the same researchers also reported, in a 2012 paper in Personality and Social Psychology Bulletin, that expressing anger when you're in a position of low power merely irritates your opponent and leads to a backlash. If you have less power than your opponent, they found, showing
disappointment is a better strategy than expressing anger, as it can induce feelings of guilt in your opponent.
Expressing anger can sometimes benefit all the parties involved , not just one of them, by clarifying boundaries , needs and concerns . Think of the loved one who doesn't realize how strongly you feel about the relationship until you express feelings of frustration with it. In a 2009 article in Negotiation and Conflict Management Research , the authors found that anger is more likely to lead to such mutually positive outcomes when it is low in intensity; expressed verbally rather than physically; and takes place in an organization that considers it appropriate (like a labour union or a university athletic department).
Finally , anger can also motivate large- scale political progress. Researchers reported in the Journal of Conflict Resolution in 2011 that among Israeli Jews, inducing anger at Palestinians increased their desire to make necessary compromises in upcoming peace talks- as long as the attitudes of the Israelis toward Palestinians were not hateful. This finding suggested that while some angry people may try to remedy a frustrating situation with aggression, others- even those who are just as angry- may funnel their anger into less antagonistic solutions.
We tend to associate anger with the loss of control , but anger has clear applications and obeys distinct rules. It may be blunt, but it has its own particular logic. And used judiciously , it can get us better deals, galvanize coalitions and improve all our lives.

Big Data , Analytics and the Cloud
BIG DATA CAN BE MINED FOR INSIGHTS TO IDENTIFY TRENDS, PREDICT BEHAVIOR , AND EMPOWER DECISION MAKING
The Nepal earthquake in April claimed more than 9,000 lives and left crores of property damaged. While an earthquake is a natural disaster, many of us are wondering why earth- quakes cannot be predicted the same way as Tsunamis or cyclones ? Scientists say it is possible to identify the key regions where earthquakes can occur, but not predict the ex-act time when they would occur. This is because predicting an earthquake means analyzing past data and factors such as high temperatures, gas emissions , strange animal and abnormal cloud formations - appearing along the traditional fault lines. Bringing all these diverse parameters together and analyzing them is a difficult task as the volume and diversity of data makes it tough for analysis.
However, the advent of Big data, has given hope. One company called Terra Seismic says that earthquakes can be predicted 20 to 30 days before they occur . Using Big Data and satellite technology, the firm claims to process large volumes of satellite data taken each day from regions where the probability of an earthquake is huge. This data is combined with a huge number of earthquake precursors ; algorithms are built and analysed to judge the probability of an earthquake.
This means Big data is not just about the data ; the real value is in the analytic and the ability to use that intelligence to gain a desired outcome . Big data can be mined for insights to identify trends, predict behavior , and empower decision making. As we move into an era of the Internet of Everything (IOE) organisations that can find the intelligence in data resulting from numerous new connections can create new sources of competitive advantage. As big data grows, the challenge to achieve better business outcomes will become more complex. Smart organisations in both the public and private sectors must leverage the power of data and analytic to improve processes and profits or to reduce costs and risk.
Going back to the Nepal earthquake one interesting observations is that big data was used to help folks outsides of Nepal locate missing loved ones and to direct disaster aid and supplies to where and when needed. What may be even more interesting, is how ' the crowd ' utilized big data to become a factor in disaster response. Cloud based data companies such as Google and Facebook which generate huge data have also developed specific tools that helped to trace and contact people in disaster areas.
Talking of cloud based data and analytic, in today's era of increasing connectivity, businesses are using the web , social, mobile and other platforms to share their data (read information ) and gather data to understand their standing in the market . Social media platforms like Twitter and Facebook provide several real time analytic capabilities leveraging big data running within their cloud environment for users to gain real time insights.
Likewise several organisations today run their websites on cloud, weblogs are generated in the cloud and analytic can also be done via Had don on the cloud itself. More and more mobile applications now typically have their back end processing in the cloud. As a result , the data that is being collected from the mobile app is in the cloud where the mobile back end resides, and consequently analyzing that data can be easily done there as well.
Clearly several new sources of data to be analysed are already in the cloud. Organisations going forward might actually need to combine their data sitting in different clouds to generate new insights. Technologies concepts like Cisco's Inter cloud which helps connect various clouds will be an integral part of that next step.

Meaning of Management Accounting
Meaning of Management Accounting
Management Accounting is the presentation of accounting information in such a way as to assist management in the creation of policy &day to day operation of an undertaking. Thus, it is related to the use of accounting data collected with the help of financial & cost accounting for the purpose of policy formulation, planning, control,& decision making by the management. Some leading definition of management accounting are given below:
Institute of cost & Management Accountants, U.K, defines -"Management Accounting is the application of professional knowledge & skill in the preparation of accounting information in such a way as to assistant management in the formulation of policies & in the planning & control of the operation of the undertaking,"
According to American Accounting Association - "Management Accounting is the application of appropriate techniques & concept in processing historical & projected economics data of an entity to assist management in establishing plan foe reasonable economics objectives & in the making of rational decisions with a view towards these objectives."
In R.N Anthony's view American Accounting Association -"Management Accounting is concerned with accounting information that is useful of management."
According to saying forwarded by Bostock," Management Accountancy can be defined as the art of presenting to management such figures, whether in terms of money or other units, as well assist management to do its job."
On the basis of the above mentioned definitions, it can be concluded that management accountancy is regarded as the information that is collected, reported & defined in detail by an accountant. These financial informations & reports are properly utilised by an efficient manager to fulfil the objectives of an organisation.Thus, Management Accounting is concerned with reframing the accounting information to make it useful for the management. The above definitions also clearly indicate that any system of accounting which assist management in carrying out its functions more efficiently may be termed as management accounting.
Functions of Management Accounting
All activities related to collecting , processing , interpreting & presenting information to the management are included in the functions of management accounting. The main functions are:
1)Organising
The management accountant helps the management in organising the human & non- human resources of the business by analysing different functions & assigning specific responsibility. He/ She tries to organise the accounting & finance function of the business on the modern lines.
2) Controlling Performance
The management accountant helps in controlling the performance of the organisation by using standard costing , budegetary control , accounting ratios, cash & fund flow statement, cost reduction programmes & evaluating the capital expenditure proposals & return on investment.
3)Co-Ordinating
The management accountant increases the efficiency of organisation & maximises its profits by providing different tools of co- ordination as budgeting ,financial reporting, financial analysis & interpretation e.t.c .It helps the management by reconciling the cost & financial accounts, by preparing budgets & setting the standard cost & analysing variances in costs to facilitate management by exception.
4 ) Communication
The management accountant prepares various reports in order to communicate the result to the superiors, to motivate the employees, to exercise effective control on their activities & to about the progress of business through published accounts & returns.
5) Forecasting & Planning
Management accounting is to provide necessary information & data for making short-term& long -term forecasts & planning operations of business, For doing this, the management accountant uses techniques of statistics, like profitability, trend study of correlation & regressions, budgeting & standard costing , capital budgeting, marginal costing & funds flow statement e.t.c
These are important tools in the hands of management accountant for the planning of the business.
6) Financial Analysis & Interpretation
The management accountant analyses the data & presents it before the management in non- technical manner along with his comments & suggestions so that the owners & the top personnel in the management may understand it & take decision without any difficulty.
7) Special Studies
The management accountant tries to maximise the profits of the concerns by conducting various cost & economics studies on regular basis. He tries to determine the needs of long-term & short- term capital, recommends appropriate capitalisation for the enterprises, evaluation of alternative capital expenditure proposals & their impact on the return & profits of the concern.
8) Miscellaneous Functions
Besides the above functions, the management accountant supplies useful information to different functionals authorities, provides necessary accounting information & advice for price determination & pricing decisions & helps to make strategic decision as seasonal or temporary suspension of production ,makes or buys decisions, replacement decisions, & expansions or closure of particular division or department e.t.c .
Scope of Management Accounting
The scope of management is very wide & broad-based. It includes all information which is provided to the management for financial analysis & interpretation of the business operation. The following fields of activities are included in the scope of this subject.
1) Financial Accounting
Financial Accounting provides historical information which is very useful for future planning & financial forecasting. Financial accounting system is a must for obtaining full control & co-ordination of operation of the business.
2) Cost Accounting
It provides various techniques of costing like marginal costing ,standard costing, differential & opportunity cost analysis ,e.t.c, which play a useful role in the operation & control of the business undertaking.
3) Cost Control Procedures
These procedures are intergral parts of the management accounting process & include inventory control, time control, budgetary control & variances analysis, e.t.c.
4) Tax accounting
It is an integral part of management accounting & includes preparation of income statement,determination of taxable income & filing up the return of income ,e.t.c.
5) Reporting
The management accountant is required to submit reports to the management on the various aspects of the undertaking. While reporting , he may use statistical tools for the presentation of information as graphs, charts , index numbers & other devices in order to make the information more impressive & intelligent.
6) Internal Financial Control
Management accounting includes the internal control method like internal audit, efficient office management e.t.c.
7) Budgeting & Forecasting
Forecasting on the various aspects of the business is necessary for budgeting. Budgeting controls the activities of business through the operation of budget by comparing the actuals with the budgeted figures, finding out the deviations, analysing the deviations in order to pin out the responsibility & take remedial action so that adverse things may not happen in future. Both techniques are necessary for the management accountant.
8) Interpretation
Management accounting is closely related to the interpretation of financial data to the management & advising them on decision making.
9) Methods of procedures
In this study it includes all those methods & procedures which help the concern to use its resources in the most efficient & economical manner. It undertakes special cost studies & estimations , report on cost volume profit relationship under changing circumstances.
10) Offices Services
The management accountant may be required to maintain & control office services in some organisations. This function includes data processing, reporting on best use of mechanical & electronic devices ,communications e.t.c .
Characteristics of Management Accounting
Management Accounting is a technique of selective nature. It takes into consideration only that data from the income statement & position statement which is relevant & useful to the management. Only that information is communicated to the management which is helpful for taking decisions on various aspects of business.
1) Concerned with Future
Management accounting unlike the financial accounting deals with the forecast with the future. It helps in planning the future because decisions are always taken for the future course of action.
2) Provides Data & not the Decisions
The management accountant is taking any decisions but provides data which is helpful to the management in decisions making. It can inform but not prescribe . It is just like map which guides the traveller where he will be if travels in one direction or another. Much depend on the efficiency & wisdom of the management for utilising the information provided by the management accountant.
3) Analysis of different Variable
Management accounting helps in analysing the reasons as to why the profit or loss is more or less as compared to the past period. Moreover , it tries to analyse the effect of different variables on the profits & profitability of the concern.
4 ) No Set Formats For Informations
Management accounting will not provide information in a prescribed proforma like that of financial accounting . It provides the information to the management in the form which may be more useful to the management in taking various decisions on the various aspects of the business.
FOVEOLA
FOVEOLA
The bouquet of central cones is surrounded by the fovea bottom, or foveola ,which measures 350 um in diameter and 150 um in thickness. This avascular area consists of densely packed cones that are elongated and connected by the external limiting membrance. as a result of the elongation of the outer segments,the external limiting membrance is bowed vitreally, a phenomenon that has been fovea externa.
Both umbo and foveola represent the most visible part of the outer retina ; however , to the level of the external limiting membrance , all cones and their axons are enveloped by the processes of Muller cells, which form the vitreal inner layer and elaborate and support the internal limiting membrance. Thus, the apex-to apex arrangement of the optic cup is maintained by the processes of mullerian glia that face the apices of the pigment epithelial cells in the foveola. The high metabolic demands of the central cones are met by direct contact with the pigment epithelium , as well as through the processes of glia whose nuclei lie peripheral in the inner nuclear layer and closer to the perifoveal vascular arcades.
FOVEA
The fovea consists of the thin bottom a 22 declivity ( the clivus ) and a thick margin . The bottom , or foveola , was described earlier. The declivity of 22 denotes the lateral displacement of the second and third neurons in the inner nuclear layer, which includes most of the nuclei of its mullerian glia . The avascular foveola is surrounded by the vascular arcades, a circular system of capillaries. These vessels are located at the level of the internal nuclear layer and leave an avascular zone of 250- 600 um between them. The declivity also is associated with an increase in basement membrance thickness, which reaches a maximum at the foveal margin. Internal limiting membrance thickness and strength of of vitreal attachment are inversely proportional : that is , adhesions are strongest in the foveola.
PARAFOVEA
The parafovea is a belt that measures 0.5 mm in width and surrounds the foveal margin.
At the distance from the centre, the retina features a regular architecture of layers, which includes 4-6 layers of ganglion cells and 7-11 layers of bipolar cells.
PERIFOVEA
The perifovea surrounds the parafovea as a belt that measures 1.5 mm wide. The region is characterized by several layers of ganglion cells and six layers of bipolar cells .
MACULAR OR CENTRAL AREA
The umbo, foveola , fovea parafovea , and perifovea together constitute the macula , or central area . The central area can be differentiated from the extra-areal periphery by the ganglion cell layer . In the macula , the ganglion cell layer is several cells thick: however, in the extra- areal periphery, it is only one cell thick . The macular border coincides with the course of the major temporal arcades and has an approximate diameter of 5.5 mm . As measured along the outside of the sclera, the centre of the macula lies 4.5 mm temporal to the centre of the optic nerve and 3.0 mm temporal to the temporal margin of the optic nerve. The surface landmark of the macula is in close proximity to the insertion of the inferior oblique muscle , being 1 to 2 mm posterior and 1 mm above the nasal limit of insertion of the muscle into sclera.

Factors influencing the Natural course of Diabetic Retinopathy and macular oedema
Factors influencing the Natural course of Diabetic Retinopathy and macular oedema
a) Duration of diabetes
All people with diabetes mellitus are at risk - those withType I diabetes and those with Type II diabetes. The longer a person has diabetes, the higher the risk of developing some ocular problem. Between 40 to 45 percent of Americians diagnosed with diabetes have some stage of diabetic retinopathy. After 20 years of diabetes , nearly 99% of patients with type I and 60% with type2 had some degree of diabetic retinopathy and 3.6% of younger - onset patients (aged < 30 years at diagnosis, an operational definition of type J diabetes ) and 1.6% of older onset patients ( aged < 30 years at diagnosis , an operational definition of type 2 diabetes ) were found to be legally blind. In the younger - onset group, 86% of blindness was attributable to diabetic retinopathy . In the older- onset group, where other eye diseases were more common , one third of the cases of legal blindness were the result of diabetic retinopathy.
b) Glycaemic Control
There is an indirect relationship between the glycaemic controls and the development and progression of DR. DCCT and Early Treatment of Diabetic Retinopathy Study (ETDRS ) have convincingly shown the reduction in risk of progression of DR with intensive treatment. Decrease in glycosylated haemoglobin levels was associated with a significant decrease in the progression of DR as well as the incidense of PDR . Intensive diabetic control leads to reduction in the development and progression of all diabetic complications.
c) Age and Sex
The prevalence and severity of DR increases with increasing age in type I DM but donot increase in type II DM.
d) Hypertension
Studies, such as WESDR and UKPDS , suggest that hypertension increases the risk and progression of DR and DME. In UKPDS , tight control of blood pressure resulted in 34% reduction in progression of retinopathy with 47% reduced risk of deterioration in visual acuity of three lines.
e) Nephropathy
The presence of gross proteinuria at baseline has been reported to be associated with 95% increased risk of developing DME among type I patients in the WESDR . The prevalence of PDR was much higher in patients with persistent microalbuminuria .
f) Genetics
In WESDR , patients with HLA DR4 and absent HLA DR3 were found to be at a greater risk of having PDR. Data from the DCCT also suggested genetic predisposition diabetes . However , it is probable that both genetic and environmental factors play a role in the expression of DR .
g ) Serum Lipid
In WESDR , higher total serum cholesterol was associated with increased risk of having retinal
hard exudates. ETDRS has reported a positive correlation between serum lipids and risk of retinal hard exudates in type 2 DM . Recently , Gupta et al. have reported reduction in oedema , severity of hard exudates and subfoveal lipid migration in patients with type 2 diabetes and dyslipidaemia , using a lipid - lowering drug , atorvastatin , as an adjunct to macular photocoagulation.
h ) Anaemia
In ETDRS , low hematocrit levels At baseline were identified as independent risk factor for the development of high - risk PDR and severe visual loss. It showed an increased risk of retinopathy in patients with the haemoglobin level of less than 12 g/ dl . Anaemia -induced retinal hypoxia is speculated as cause of development of microaneurysms and other retinopathy changes.
i ) Puberty
In the WESDR , younger on set subjects who were post-menarchal stood a 3.2 times greater risk of developing DR as compared to pre- menarchal subjects. Those who were older than 13 years at the time of diagnosis were likely to have retinopathy than those who were younger. The exact mechanism by which puberty might exert its effect on the development of early retinopathy is not yet understood , but a possible role of hormonal factors is suspected.
j ) Socioeconomic Status
Although educational attainment was inversely associated with retinopathy in women in the WESDR , socioeconomic status was not associated with increased risk of worsening of retinopathy. Once the level of glycaemia is accounted for , social factors have little or no influence on this complication of diabetes .
k) Pregnancy
Pregnant women with type 1 diabetes have twice the risk of developing PDR than non- pregnant women . Ideally , young mothers should be examined for retinopathy before the onset of pregnancy. The cause of acceleration of DR may be a simple reflection of long duration of diabetes or there may be factors , both metabolic and hormonal , that contribute to the overall deterioration of DR in the pregnant patient .
Ocular conditions are : Status of posterior vitreous , intraocular pressure, Ocular perfusion pressure, Refractive error , intraocular surgery like cataract and glaucoma , intraocular infection and inflammation .
Acute Pain in Female Patient
Acute Pain in a Female Patient
INTRODUCTION
Large number of patients with abdominal and pelvic pain are reffered to both the gynecologists and surgeons . The vast majority of cases will be found to have no organic basic and will be categorized as irritable bowel syndrome, spastic colon, pelvic inflammatory disease or even "psychosomatic".
The current view is that pains are pains are real and that doctors should not adopt a dismissive attitude. Several factors including infections , endocrine disorders,pregnancy,childbirth,previous surgery could all be implicated. In addition there could be a psychological overlay with stress and social problems.
In the chapter we hope to address the differential diagnosis, discuss the recent investigative modalities and the most appropriate treatment for acute pain from reproductive and intestinal tract.
Most causes of pain fit into three categories :
1 . Causes that originate in the reproductive tract.
2. Causes that originate in the intestinal tract.
3. Causes that originate in the urinary tract.
THE ORIGINS OF PELVIC PAIN
THe rectum, lower colon , cecum, appendix, terminal ileum , bladder and gynecological organs are so closely related and the localization of visual pain so poor that it is not surprising that pelvic pain could be seen by a variety of specialists . Pain from these areas is largely perceived via the sympathetic nervous system and there is shared innervations of the vagina cervix inner third of fallopian tubes broad ligament , upper bladder , terminal ileum and large bowel. The pain travels via the hypogastric plexus and hypogastric nerve to the lower thoracic and lumbar sympathetic chain . The afferents enter the cord between T10 -L1. Pain from the colon also travels via the parasympathetics to the pelvic plexus , pelvic nerves and enters the cord at S 2-4. The outer third of the fallopian tube and urethra are innervated differently and the afferents enter the cord between T 9 and T10. The lower vagina , lower bladder and rectosigmoid junction are innervated by sacral afferents. The localization of pain is dependent upon convergence of visual and somatic nerves within the central nervous system in the anterior horn . Referred pain is thought to be due to the shared connections of the afferent nervous system in the posterior root ganglia. Reffered patterns may lead to quite unusual and unexpected sites of pain.
ECTOPIC GESTATION
· It is necessary to exclude an ectopic pregnancy in all women of reproductive age group married or otherwise. The patient's last menstrual period and sexual activity pattern are useful but do not eliminate the need to do a pregnancy test. A simple urine pregnancy test will detect BhCG of even 20 mIU/ml. If inconclusive a serum BhCG should be done . In subacute presentations when diagnosis is not obvious non- invasive tests namely high resolution transvaginal scan and serial BhCG estimations are useful. Normally developing intrauterine pregnancies will have a characterstic doubling rate of BhCG of 1.98 days . When the BhCG does not double it is suggestive of a falling intrauterine pregnancy or an ectopic gestation. If subsequent BhCG values show a declining trend,one can wait without surgery or medical treatment. Often several BhCG estimations and ultrasound have to be performed before a definitive diagnosis is made . Laparoscopy which used to be the gold standard for diagnosis is made. Laparoscopy which used to be the gold standard for diagnosis is seldom needed to diagnose an ectopic gestation . Generally , one should be able to see a gestational sac with a quant of 1000 miu/ mi. Identifying an intrauterine sac does not exclude a co-existing ectopic pregnancy , defined as heterotopic pregnancy . This is rare , 1 in 5000 pregnancy but is increasing with more women undergoing treatment with artifical reproductive techniques (ART) and pelvic inflammatory disease(PID) .
· Once an ectopic pregnancy is diagnosed further management depends on the level of BhCG and the size of the ectopic gestational mass.

Risk Factor Analysis of Diabetic Macular Oedema
RISK FACTOR ANALYSIS OF DIABETIC MACULAR OEDEMA
Background : Diabetic retinopathy is the most common cause of newly diagnosed legal blindness amongst the working population in the industrialized world today.The common cause of visual impairment in diabetic retinopathy include macular oedema & complication due to proliferative retinopathy. The majority of diabetics have type II disease, wherein macular oedema is commoner, it follows that overall, macular oedema accounts for more vision impairment than proliferative retinopathy. Hence evaluating possible relationship between diabetic macular oedema & various risk factor helps as preventive measure for progression of disease.
Methodology:
Eyes were diagnosed with diabetic macular oedema according to ETDRS guidelines. Best corrected visual acuity with Smelled vision drum, slit lamp examination of anterior segments, and fund us evaluation with slit lamp bio microscopy using + 90 Volk lens was done. Fasting plasma samples after at least an 8 -h overnight fast were collected for lipid analysis in blood . Other investigation blood sugar, haemoglobin, serum creatinine were assessed. Existing of hypertension noted. Ocular risk factor like cataract surgery was included.
Results: Most cases presented with vision between 6/18 to 6/60 constituting 35 eyes (43.75%) followed by 22 eyes (27.5%) had normal vision 6/6 to 6/18 , 10 eyes (12.5%) low vision category 2, 6/60 to 3/60 and remaining 13 eyes (16.25%) were in blindness category 3, 3/60 to 1/60 . Males 37 (74 % ) were affected more than females 13 (26%) . Mean duration of DM was 9.28=6.15 years. The P value of 0.019 for serum cholesterol to diabetic macular oedema is statically significant . P value for LDL , HDL ,triglycerides, haemoglobin serum creatinine and surgery was not significant . Chi square test was used to see the association between groups for categorical variables. Results were considered significant at 'p' < 0.05 .
Conclusions:
Total serum cholesterol appears as an important risk factor for incidence and progression of diabetic macular oedema. Most of the cases were in age group of 51 to 60 years. Male were predominantly affected .The maximum patient had low vision category 1 constituting 35 eyes (43.75%) . Duration of diabetes mellitus and diabetic macular oedema was not related indicating perhaps DME can occur at any stage of diabetic retinopathy. Cataract surgery , hypertension , serum creatinine, haemoglobin were not significantly related to diabetic macular oedema. As the study was carried out in small number of patient , further study with large number of patient is needed .
