Abstract (English)

Abstract
Aim: The aim of the present study was to estimate prevalence and severity of DR and in recently diagnosed type
2 DM patients.
Material & Methods: A study was conducted in the Department of Ophthalmology, Nalanda Medical College
and Hospital, Patna, Bihar, India from February 2017 to January 2018. This observational, prospective study was
conducted in patients who visited the diabetic clinic and recently diagnosed (less than 3 months from first
diagnosis) for type 2 DM. In present study total 100 patients were evaluated for diabetic retinopathy.
Results: In present study total 100 patients were evaluated for diabetic retinopathy. Most of patients were from
61-70 years (25%), followed by 51-60 years (22%) and 41-50 years (20%) age group. Male patients (58%) were
more than female patients (42%). We noted 10% prevalence of diabetic retinopathy in study patients. Prevalence
was more in males (66.66%) as compared to females (33.33%). In present study diabetic retinopathy was noted
in 15 patients, divided as mild no proliferative diabetic retinopathy (66.66%), Moderate no proliferative diabetic
retinopathy (20%), Severe no proliferative diabetic retinopathy (6.66%) and proliferative diabetic retinopathy
(PDR) (6.66%). Macular oedema was noted in 4 patients. 60% of them had mild macular oedema while 20% each
had moderate and severe macular oedema.
Conclusion: Screening for diabetic retinopathy is important for newly diagnosed diabetic patients. A systematic
screening program in the community is needed for early detection and to reduce blindness in diabetic patients
