Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 5
Abstract
Aim: To study correlation between VFI and Diabetic Retinopathy. Material and Methods: This study was done in Dept of Ophthalmology in tertiary care hospital. 100 known diabetic patients were included in this study. Detailed fundus examination was done. 200 eyes of 100 patients were classified into stages of diabetic retinopathy according to ETDRS classification from No DR to Proliferative diabetic retinopathy. Corresponding VFI of each eye was assessed by using Humphrey Automated Perimeter(30-2).Graphs were plotted for average VFI for each stage of diabetic retinopathy. Results: VFI decreases as severity of Diabetic retinopathy increases with even patients with no DR stage showing decrease in VFI Compared to VFI of non-diabetic patient by 1.75%.which is statistically significant. Conclusion: Diabetic retinopathy in itself reduces VFI which decreases as severity of disease increases. VFI testing may act as a predictor of retinal involvement in diabetes.
