Axial Length and its Influence on Diabetic Retinopathy

Vaishnavi J .

Abstract


Objective: To evaluate the correlation between axial  length  and diabetic retinopathy. Study Design:  Cross-sectional study. Place and Duration of Study:  Department of Ophthalmology, Government Stanley Medical College from Jan 2016-Dec 2016 Methodology: A total of100 participants suffering from type-2 diabetic retinopathy were included. Axial length was measured using contact type    ultrasound biometer. Colored retinal photographs, red free retinal photographs and Fundus Fluorescein Angiography (FFA) were performed on all patients using standard fundus camera. Results: Out of 100 patients, 71 were males (71%) and 29 (29%) were females. Average age of   patients was 56.30 ± 7.57 years with minimum age observed as 38years and maximum of 76 years .Average axial length of right and left eyes were 23.16 mm and 23.15 mm respectively. There was significant negative correlation between AL and severity of DR in both eyes, with Spearman correlation of -0.511 and p < 0.0001(right eye Spearman correlation = -0.469, p < 0.0001 and left eye Spearman correlation = -0.552, p < 0.0001)   Conclusion: There is a protective influence of longer axial length of globe on the stage and severity of diabetic   retinopathy. This study may help in modifying the screening protocol for diabetic retinopathy amongst patients of differing axial lengths.
