Abstract

As Diabetes Mellitus is a known risk factor for POAG, we analysed and compared the peripapillary microvascular alterations in glaucomatous eyes in patients with and without diabetes and age-matched healthy eyes using OCT angiography. A total of 128 eyes (32 eyes in 4 groups) underwent OCT-A imaging. Parameters assessed were retinal nerve fibre layer thickness, perfusion percentage and flux index in peripapillary area and vessel densities in the foveal avascular zone area in 4 groups (Cases- Glaucoma with and without Diabetes, Controls- with and without Diabetes). Our study found that the perfused capillary density in the peripapillary region and vessel density in the FAZ area was significantly reduced in patients with Glaucoma with Diabetes group as compared to Controls. Diabetes induced peripapillary vessel changes had no additional role in augmenting optic nerve damage in glaucomatous eyes.
