Giridhar, Dr. S. J. Saikumar, Dr. Ram Kumar, Dr. Savita Bhat(Presenting Author: Dr. Mahesh G)Diabetic retinopathy is a major public healthproblem. It is one of the most commonvascular complications of diabetes mellitus (DM)<strong>and</strong> one of the main causes of new cases ofblindness among active people in the workplace.Diabetes mellitus affects 4 per cent of the world’spopulation, almost half of whom have somedegree of DR at any given time. It is estimatedthat in the developed world, the increase isapproximately 46%, from 55 million in 2000 to 83million in 2030; whereas, among developingnations, the increase is approximately 150%, from30 million in 2000, to 80 million in 2030. India had31.7 million diabetics in year 2000 with aprojection to reach 79.4 million by year 2030 asper the World <strong>Health</strong> Organization (WHO)estimates.Prevalence of DR in Wisconsin EpidemiologicalStudy of Diabetic Retinopathy (WESDR) was50.1% <strong>and</strong> 54.2% in the diabetes control <strong>and</strong>complications trial (DCCT) in IDDM <strong>and</strong> 35-39%in United Kingdom Prospective Diabetes Study(UKPDS) in NIDDM. In the Andhra Pradesh EyeDisease Study (APEDS) of self-reported diabetics,the prevalence of DR was 22.4%.This study was conducted to evaluate theknowledge, attitude <strong>and</strong> practice (KAP) patternsin the management of Diabetic Retinopathy (DR)among ophthalmologists <strong>and</strong> physicians.
COMMUNITY / SOCIAL OPHTHALMOLOGY SESSION165Materials <strong>and</strong> methods:The study was a cross-sectional study conductedamong medical professionals who includedgeneral physicians <strong>and</strong> ophthalmologists.Responses were obtained using a semi-structuredmulti point questionnaire survey that includedbasic demographic data regarding therespondents <strong>and</strong> the setup in which they wereworking. The survey questionnaire did notinclude personal details of the responders.Questions regarding diabetic retinopathy wereassessed in 3 sections of knowledge; attitude <strong>and</strong>practice patterns. A separate questionnaire wasused for physicians <strong>and</strong> ophthalmologists.Physician’s questionnaire included basics ofophthalmology <strong>and</strong> diabetic retinopathy taughtat the undergraduate level. It included 10questions about knowledge, 7 questions aboutattitude <strong>and</strong> 5 questions about practice patternsfor diabetic retinopathy. The questionnaire forophthalmologists included 8 questions aboutknowledge, 7 questions about attitude <strong>and</strong> 7questions about practice patterns. Verbalinformed consent was obtained from all subjectswho participated in the study.ResultsA total of 76 ophthalmologists <strong>and</strong> 29 physicianshad responded to the survey questionnaire.Analysis of data was done separately forophthalmologists <strong>and</strong> physicians.OPHTHALMOLOGISTSDemographic data: A total of 76 ophthalmologistsresponded who included 26 males (34.21%)<strong>and</strong> 47 females (61.84%). Mean age of responderswas 42.42 ± 9.47 yrs. (minimum 27 to maximum61 yrs). 59 out of 76 (77.64%) respondentshave been practicing ophthalmology for morethan 5 years. 31of 76 40.79% responders were ingovernment service. 57 of the responders (75%)were general ophthalmologists while only 9 of76 (11.84%) were retina specialists. Percentage ofdiabetic patients seen in their general practicewere less than 10% in 06 (7.89%), 10 to 25% in 35(46.05%), 25 to 30% in 20 (26.32%) <strong>and</strong> more than50% of patients in 10 (13.16%).<strong>Knowledge</strong> pattern: 50 respondents (65.79%)said that they diagnose clinically significantmacular edema using slit lamp biomicroscopy. 22(28.95%) respondents stated that FBS more thanor equal to 110 <strong>and</strong> PPBS more than or equal to130 was criteria for diabetes mellitus while 34(44.74%) stated that FBS more than or equal to120 <strong>and</strong> PPBS more than or equal to 140 can beconsidered diagnostic of diabetes mellitus. 75(98.68%) stated that refractive error can be altereddue to blood sugar level. 67 responders (88.16%)stated that lipid profile ,glycaemic control,hypertension <strong>and</strong> renal disease can affect theprogression of retinopathy. IndirectOphthalmoscopy with Slit lamp Biomicroscopywas considered ideal examination to evaluate thediabetic fundus by 71 (93.42%). 53 (69.74%) wereof the opinion that Clinically significant macularedema <strong>and</strong> High risk PDR are indications forlaser photocoagulation. 71 (93.42%) opined thatnormal visual acuity in the presence of significantdiabetic retinopathy warrants treatment. Mostcommon indications of fluorescein angiographywere CSME before laser photocoagulation 39(51.32%).<strong>Attitude</strong> pattern: 31 responders (40.76%) use Slitlamp <strong>and</strong> Lenses while another 33 (43.42%) useboth slit lamp with lenses <strong>and</strong> indirectophthalmoscopes in their routine practice. 60(78.95%) are of the opinion that fasting bloodsugar level of Less than 120 is ideal for apreoperative cataract surgery patient on the dayof surgery. 73 (96.05%) ophthalmologists wouldlike to know the recent blood sugar level beforeprescribing glasses to their patients. 69 (90.79%)treating ophthalmologists would like to know therecent serum cholesterol <strong>and</strong> renal parameters ofdiabetic patients. 65(85.53%) are of the opinionthat visual acuity is not the single most importantindicator for the treatment of diabeticretinopathy. 64 (84.21%) are of the opinion thatretinal examination should be performed onlyafter dilatation. 51 (67.11%) are of the opinionthat FFA is not required for treatment of alldiabetic retinopathy cases.<strong>Practice</strong> pattern: Only 56 (73.68%) do slit lampbiomicroscopy examination in all diabeticpatients. 52 (68.42%) check blood sugar in allpreoperative cases on the day of surgery while 21(27.63%) do not check sugars. only 56 (73.68%)check the fasting blood sugar of their diabeticpatients routinely. 41 (53.95%) do not routinelyask for the serum lipid profile, HbA1c <strong>and</strong> renalparameters. 37 (48.68%) use indirectophthalmoscopy <strong>and</strong> slit lamp biomicroscopyroutinely for fundus evaluation followed by 16
166 AIOC 2010 PROCEEDINGS(21.05%) who use direct Ophthalmoscopy <strong>and</strong>slit lamp biomicroscopy. 44 (57.89%)ophthalmologists refer their patients to a retinaspecialist when they suspect proliferativediabetic retinopathy. 44 (57.89%) are of theopinion that frequency of periodic retinalevaluation depends on stage of retinopathy <strong>and</strong>visual acuity while 25 (32.89%) respondersconsider yearly examination is enough forfundus examination.PHYSICIANSDemographic data: A total of 29 physiciansresponded who included 19 (65.52%) males <strong>and</strong>10 females (34.48%).Mean age of respondentswas 55.36 ± 8.97 yrs. (35 to 78 yrs). 25 (86.21%)had been practicing for more than 15 years. 14(48.28%) were doing Individual Private <strong>Practice</strong>.12 (41.38%) physicians said that diabeticsconstitute less than 10% of their patients while 11(37.93%) said that diabetics constitute 10 -25% oftheir patients.<strong>Knowledge</strong> pattern: 29 (100%) physicians are ofthe opinion that diabetic retinopathy is a blindingdisease. 27 (93.10%) are of the opinion thatretinopathy is related to the duration of diabetesmellitus. 26 (89.66%) agreed that patients canhave advanced diabetic retinopathy changes inspite of having good vision. 28 (96.55%) said thatall diabetic patients should have periodicalretinal examination. 22 (75.86%) opined thatLaser treatment is curative for diabeticretinopathy. Only 18 (62.07%) said that surgicaltreatment is available for advanced diabeticretinopathy. 27 (93.1%) agree that serum lipidprofile is related to the severity of diabeticmaculopathy. 29 (100%) agree that hyper tension<strong>and</strong> renal disease can influence the diabeticretinopathy. 20 (68.97%) are of the opinion thatpregnancy can worsen diabetic retinopathy. 16(55.17%) said that fundus fluoresceinangiography is the ideal method to detectdiabetic retinopathy.<strong>Attitude</strong> pattern: 26 (89.66%) disagree with thestatement that eye examination is required indiabetic patients only when vision is affected. 15(51.72%) are of the opinion that a newly detecteddiabetic patient do not require eye check ups. 27(93.1%) are of opinion that diabetic patientsrequire an eye examination at yearly interval. 26(89.66%) agree that Laser treatment can preventblinding complications in up to 50% cases withdiabetic retinopathy. 22 (75.86%) of physiciansthink that FFA is required for evaluation of alldiabetic retinopathy cases. 25 (86.21%) agree thata good lipid profile is essential for preventingvision loss in diabetic retinopathy.<strong>Practice</strong> pattern: 24 (82.76%) advise diabeticpatients an eye evaluation as soon as diabetes isdetected. 26 (89.66%) will advise another eyecheckup after an year if there is no retinopathy atinitial examination. 29 (100%) physicians checkthe lipid profile of their diabetic patients. 16(55.17%) advise retinal evaluation every trimesterfor diabetic pregnant patients. 17 (58.62%) dodirect ophthalmoscopy to examine diabeticpatients.DiscussionThe American Academy of Ophthalmology(AAO) recommends that the first fundusexamination (FE) in patients with type 1 diabetesshould be performed 5 years after diagnosis ofthe disorder, because retinopathy is rarelyobserved before this period. However, patientswith type 2 diabetes should be examinedimmediately when they are diagnosed, becausethe duration of the disease is uncertain, so somedegree of retinopathy may be present at this time.The findings at this first examination willdetermine the frequency of subsequent tests.76 ophthalmologists <strong>and</strong> 29 physicians participatedin the multi point questionnaire survey.<strong>Among</strong> the ophthalmologists 52.26% were notsure about the current definition of diabetesmellitus. 93.4% knew that the ideal method ofexamination is indirect ophthalmoscopy with slitlamp biomicroscopy. But this was practiced byonly 48.6% ophthalmologists. Even though theknowledge about the role of hyperlipidemia <strong>and</strong>glycosylated hemoglobin in the pathogenesis ofDR was good (89.5% correct) only 40.78%checked it routinely. 32.9% felt once a year checkup for DR was adequate whatever the stage ofretinopathy be. <strong>Among</strong> the physiciansinterviewed the knowledge regarding the role ofduration of diabetes, its blinding complications<strong>and</strong> the role of systemic parameters were good(>75% responses correct). Some of themisconceptions were laser is curative in DR(75.9%), a newly detected diabetic does notrequire retinal evaluation (51.7%) <strong>and</strong> fluoresceinangiography is required for the diagnosis of DR
COMMUNITY / SOCIAL OPHTHALMOLOGY SESSION167(75.9%). 58.6% physicians used directophthalmoscope to evaluate retinopathy.The survey highlights some of the lacuna in ourhealth care systems. Most of theophthalmologists are well aware about theconsequences of diabetic retinopathy. Theyknow the ideal method of examination beingindirect ophthalmoscopy <strong>and</strong> slit lampbiomicroscopy. But this is not practiced bymany. The ophthalmologists are not sure aboutthe current definition of diabetes mellitus. Sothere is a need for awareness creation amongophthalmologists about the recent changes in themanagement of diabetes mellitus. Nearly all theophthalmologists would like to know the bloodsugars before prescribing glasses. But only 40%uses slit lamp <strong>and</strong> indirect ophthalmoscope todetect blinding diabetic retinopathy. Here thereis a disparity between knowledge level <strong>and</strong>practice pattern. Slit lamp, indirectophthalmoscope <strong>and</strong> lenses are not veryexpensive accessories in an ophthalmic practice.But for most of our responders who are fromGovernment sector, this may not be available intheir practices. Here lies the importance ofimproving the infrastructure by providing thisbasic material for the fundus examination.Individual practitioners can consider getting allinstruments which will improve the quality oftheir work. Once the infrastructure is availableit need not be a problem for the ophthalmologistto put their knowledge into practice. All that isrequired is to make the ophthalmologists awareabout this simple practice which can detect earlydiabetic retinopathy. Continuing medicaleducation programme can be had for generalophthalmologists to improve their examinationskills.Regarding physicians, many of them know the1.

DHEW publication no. 1970;73-Referencesconsequences of untreated diabetic retinopathy.But there are some misconceptions amongphysicians like laser is curative for diabeticretinopathy <strong>and</strong> FFA is needed for diagnosis ofdiabetic retinopathy. Physicians need to betrained regarding management of strategies ofdiabetic retinopathy. It is good to see that manyphysicians do simple direct ophthalmoscopy tolook for diabetic retinopathy. In another surveydone by us in one whole panchayath inErnakulam most of the self confessed diabeticpatients felt that they were not adequatelyinformed about the need for periodic evaluation<strong>and</strong> the significance of blinding problems ofdiabetic retinopathy. Only 1/3 of the patientswere informed by the treating physicianregarding all these. Here also there is disparitybetween the knowledge of the physician <strong>and</strong>practicing. Physicians have to be made awareabout the need for patient education by them.This simple practice can detect early treatableretinopathy in a considerable number of cases.Even though the number of participants is few inour study it gives a glimpse to knowledgeattitude <strong>and</strong> practice pattern among health careproviders in our study. It is unique in the sensethat both ophthalmologists <strong>and</strong> physicians aresurveyed. They constitute the main health careproviders in diabetic retinopathy. To ourknowledge there are no such published reportsof similar studies. In this highly literate state withhighly knowledgeable health care providers itrequires just a little motivation to put all theseknowledge into practices. A combined effort byGovernment <strong>and</strong> nongovernmental organization,physicians, ophthalmologist <strong>and</strong> otherparamedical staff can result in better patient care.This can avert an explosive situation of diabeticblindness which is snowballing in our country.427.4.

During discussionit was advised that being a life style disease the course, causes,history, medication <strong>and</strong> health education is theneed of the hour <strong>and</strong> it is the mutispeciality disorder <strong>and</strong> the ophthamlogist should be updated <strong>and</strong> should give moretime to patients. It is eye-opener that rural population is equally suffering from DM.
