Peripapillary and Macular Microvascular Density after Selective Laser Trabeculoplasty in Exfoliative Glaucoma: OCT-Angiography Stady on 30 Cases

Abstract

Exfoliative glaucoma is a particularly aggressive type of open-angle glaucoma, characterized by a faster rate of progression and poorer response to medical therapy [1]. Selective laser trabeculoplasty is a safe and noteworthy treatment option to reduce IOP exfoliative glaucoma eyes, especially with pre-SLT intraocular pressure (IOP) over 18 mmHg [2]. We present a prospective study on 30 eyes with exfoliative glaucoma with high intraocular pressure treated by Selective Laser Trabeculoplasty (SLT). Fifteen (15) patients were involved in the study and were followed up over a period of 6 months. The peripapillary and macular microvascular density increased temporarily before returning to their initial values after 6 months. No correlation was found between microvascular fluctuations and IOP. The aim of this study is to evaluate the changes in the microvascular density (VD) of the periparipillary and the macular area using OCT angiography before and after the treatment by Selective Laser Trabeculoplasty.
