Evaluation of Visual Function with Different Illumination for Diabetic Retinopathy Patients Post Ocular Management

Abstract

Background: India, the country with the most diabetics in the world with over 62 million diabetics. As increase in diabetes which is directly proportional to increase number of diabetic retinopathies in future Aim: To evaluate the visual performance of diabetic retinopathy patients after ocular treatment with various LED lights Methodology: This experimental investigation comprised 35 diabetic retinopathy patients treated with laser treatment or Anti-VEGF medication. On the basis of MN Read guidelines, participants with best-corrected visual acuity (BCVA) between 1.3 Log MAR and -0.5 Log MAR were included in the research. The comprehensive optometric assessment comprised a detailed medical history and best-corrected visual acuity (BCVA) for distance and near. The patient’s reading performance was next evaluated with MN Read acuity in three light circumstances, i.e., normal room illumination, an overhead projection of white LED and yellow LED, and constant 400 lux intensity. Results: The mean age of the participants was 58.6 ± 6.44 years. Data were analysed using one-way ANOVA for comparison of reading and functional performance under normal room illumination, white LED and yellow LED in diabetic retinopathy patients’ post-treatment. The scores derived from this analysis showed that there is no significant difference between reading performance, functional performance, and different illumination (p=0.05). Conclusion: Present study conclude that lighting had no influence on reading performance (Critical print size, reading speed, and reading acuity) and functional performance (Contrast sensitivity and colour vision) in diabetic retinopathy patients after therapy. Nevertheless, present study data indicate that white lighting increased reading speed and yellow illumination enhanced colour vision in diabetic retinopathy patients after therapy.
