Purpose

To assess retinal microcirculation in patients with different stages of diabetic retinopathy and controls in an analytical observational study.

Setting/Venue

The current research includes seventy-four eyes from seventy-four subjects consulted in the Retina Clinic, Bucharest, in 2019 and 2020.

Methods

Adaptive optics ophthalmoscopy was used to measure the parameters of temporal retinal arterioles. Optical coherence ophthalmoscopy angiography was employed to assess foveal avascular zones and vessel densities of the superficial capillary plexuses.

Results

Diabetic patients with or without diabetic retinopathy presented retinal arterioles structural changes, depicted mainly by altered values of wall to lumen ratio and of vascular density in the retinal superficial capillary plexus.

Conlusions

Both adaptive optics ophthalmoscopy and optical coherence tomography angiography are providing useful information about the retinal microvasculature in diabetic patients, having a high potential to bring important information on the prognostic and pathophysiology of the disease in the future.
