Abstract

Purpose: Diabetes is a leading cause of visual impairment in working age population in the UK. This study looked at the causes of Severe Visual Impairment(SVI) in the patients attending diabetic eye clinic and influence on the rate of SVI, over a 12 year period, after introducing retinal screening programmes in the hospital and the community in 1993 (review in 1992, 1998 & 2004). Methods: Medical records of all the patients attending the diabetic eye clinic over a period of 5months(April to August) in 1992, 1998 and 2004 were reviewed. The data collected for each patient included age, sex, ethnic origin, diabetes (type,duration &treatment), the best corrected visual acuity (present and at time of presentation), type and duration of retinopathy and attendance record to both diabetic clinic and diabetic eye clinic. In this study, SVI is defined as a visual acuity of 6/36 or worse in at least one eye. Results: In 1992, of a total 245 patients, 58patients(23.6%) had SVI {38 (15.5% of total) due to diabetic retinopathy [31(12.6%) maculopathy, 2(0.8%) vitreous haemorrhage and 5(2%) retinal detachment] and 20(8.1%) due to non–diabetic retinopathy causes}. In 1998, of a total 297, 77patients(25.9%) had SVI {33(11.1% of total) due to diabetic retinopathy [19(6.4%) maculopathy, 9(3%) proliferative retinopathy, 8(2.7%) vitreous haemorrhage and 3(1%) retinal detachment]and 44(14.8%)due to non–diabetic retinopathy}. In 2004, of a total 471, 72patients(15.2%) had SVI{46(9.7%of total) due to diabetic retinopathy [37(7.8%) maculopathy, 1(0.2%) proliferative retinopathy, 6(1.8%) vitreous haemorrhage and 2(0.4%) retinal detachment]and 26(5.5%) due to non– diabetic retinopathy causes}. Conclusions: Introduction of formalised annual diabetic review including retinal screening and a community retinal screening programme has reduced the rate of severe visual impairment due to diabetic retinopathy, in patients attending diabetic eye clinic, from 15.5% in1992 to 9.7% in2004.
