Early microvascular changes in patients with prediabetes evaluated by optical coherence tomography angiography.

Background: Timely detection of early microvascular changes in patients with prediabetes could help reduce the likelihood of progression of diabetes-related retinal complications.

Aim: To determine early microvascular changes in patients with prediabetes using optical coherence tomography angiography (OCT-A).

Methods: In this single-center retrospective case-control study, macular OCT-A images of superficial capillary plexus (SCP) and deep capillary plexus (DCP) were analyzed in non-diabetic controls, and prediabetic and diabetic subjects.

Differentiation of Features of Inflammatory Neovascular Membrane Versus Active Posterior Uveitis by SS-OCTA.

Background And Objective: Neovascularization is a sight-threatening, uncommon complication of posterior uveitis that often goes undetected until persistent clinical findings appear, or in light of treatment failure. This could be attributed to the relative similarity of activity signs in inflammatory neovascular membranes (NVM) and active posterior uveitis. The purpose of the present study is to recognize imaging features that distinguish uveitic neovascularization from active uveitis using swept-source optical coherence tomography angiography (SS-OCTA).

PLASMA RICH IN GROWTH FACTORS FOR PERSISTENT MACULAR HOLE: A PILOT STUDY.

Purpose: Persistent macular hole (PMH) is a challenge for retina surgeons. There are limited surgical techniques described achieving PMH closure. For more than a decade, techniques with blood derivatives have been described without optimal outcomes.
