Abstract

AIM: To evaluate the presence of hyperreflective spots (HRS) in diabetics with and without NPDR, without macular edema and to compare the results with nondiabetic controls.

METHODS: 96 eyes of 60 subjects aged >40 years were examined. Based on fundus findings, they were categorised into 3 groups: Group A-32 eyes of diabetics with mild to moderate NPDR. Group B-32 eyes of diabetics without DR. Group C-32 eyes of normal age matched controls. SDOCT HD 15 line raster scan at the macula was performed on all the eyes. The HRS were counted in all retinal layers.

RESULTS: The HRS were present in all retinal layers and were predominantly located in inner retina in all the groups. The presence and count of HRS was high in diabetics, especially those with DR and increased with duration and severity of DR.

CONCLUSION: HRS seen as small discrete, well circumscribed, white punctiform lesions on SDOCT is a new biomarker of diabetic retinopathy.
