Prevalence of diabetic retinopathy and associated risk factors in diabetic type II patients in Ajdabiya, Libya

ABSTRACT

Diabetic retinopathy (DR) is One of the most wellknown microvascular complications of diabetes mellitus (DM) and is a frequent side effect of untreated diabetes that can lead to blindness and visual impairment. This study was conducted to assess the prevalence of diabetic retinopathy and associated factors among type 2 diabetic patients. A cross sectional study was done at Ajdabiya diabetic center from November 2023 to January 2024. Subjects and Methods: 52 patients (104 eyes) with T2DM were included in this study, their fasting blood sugar and glycosylated hemoglobin level, lipid profile measured.in addition to fundus examination (done by noncontact +90-diopter lens), fundus photographs taken by Non-Mydriatic Fundus Camera TFC-1000. Around 61 eyes (58.7%) had diabetic retinopathy, 27 eyes (26%) had back ground DR, 6 eyes (5.8 %) had pre-proliferative DR, 4 eyes (3.8%) had proliferative DR, 2 eyes (1.9%) had advanced diabetic eye disease, 22 eyes (21.2%) had CSME. Their ages ranges between 36­74 years with mean (58.90) years, (26.9%) were males, (73.1%) were females. There was a significant association between the development of DR and duration of DM (p=0.003), The FBS levels were also determined to be a significant risk factor for DR (p = 0.031), also LDL with (p=0.039). No other factors were found to have a significant association with DR. In this study more than half of diabetic patients had diabetic retinopathy. There was a significant association between the development of DR and duration of DM, FBS, LDL levels, there was no significant relation between diabetic retinopathy and hypertension, HgA1c Serum cholesterol or triglyceride levels or previous cataract surgery.
