Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 10
Abstract
Background: In 1971 Becker stated “diabetes mellitus occurs more often in patients with primary open angle glaucoma than in non-glaucomatous populations. Armstrong et al reported a prevalence of POAG of 4.1% in the diabetic patients compared with 1.4% in the controls. However a number of studies have not found association between diabetes and POAG Objectives: 1) To study the hospital based prevalence of POAG among the diabetic patients attending postgraduate department of ophthalmology G.M.C. Srinagar. 2) To screen all diabetics for glaucoma Material and Methods: This cross sectional study was conducted on 100 diabetic patients for a period of one & a half year at postgraduate department of ophthalmology G.M.C Srinagar. Diabetic patients above 50 years were selected as per inclusion and exclusion criteria. Detailed history was noted in all the patients and they underwent ophthalmic evaluation and investigation. Results: The study group consisted of 100 diabetic patients (52 females and 48 males) in the age group of 50 to 86 years with mean age of 62.15±6.48 years. Overall proportion of POAG cases observed was 5%, NTG cases observed were 2%, OH cases observed were 1% and remaining 93% patients were normal. Among POAG patients, bilateral eye involvement was seen in 4 cases while one patient had only right eye involvement. NTG & OH cases had bilateral eye involvement. Statistically no sex predisposition was present (p>0.05). Mean CD ratio of POAG & normal diabetics was respectively 0.680 & 0.400 (p<0.05). Neuroretinal rim (NRR) thinning, cupping, vascular changes and peripapillary changes were observed in glaucomatous patients. On OCT, mean linear vertical Cup Disc Ratio as well as Cup Disc Area ratio was found significantly higher in POAG & NTG patients than OH & normal patients. On OCT mean RNFL thickness was found significantly less in POAG & NTG patients than in OH & normal patients in all quadrants Conclusion: It is concluded that there is excess of POAG among diabetics; thereby showing an association between POAG & Diabeties
