Comparison of vessel density and retinal nerve fiber layer thickness in patients between both eyes of subjects with clinically unilateral pseudoexfoliation syndrome using optical coherence tomography angiography

Purpose The purpose of the study was to compare vessel density (VD) and retinal nerve fiber layer thickness (RNFLT) between eyes with pseudoexfoliation material (PE+) and fellow unaffected (PE−) eyes of patients using optical coherence tomography angiography (OCTA). Methods A retrospective analysis...

Description
Summary:Purpose The purpose of the study was to compare vessel density (VD) and retinal nerve fiber layer thickness (RNFLT) between eyes with pseudoexfoliation material (PE+) and fellow unaffected (PE−) eyes of patients using optical coherence tomography angiography (OCTA). Methods A retrospective analysis of 36 eyes from 18 patients with clinically unilateral pseudoexfoliation syndrome was performed. The circumpapillary (cp) VD and RNFLT were obtained using OCTA and perifoveal, parafoveal VD and RNFLT were also calculated using OCTA. Circumpapillary parameters were obtained from octametric sections: superonasal (SN), nasalsuperior (NS), nasalinferior (NI), inferonasal (IN), inferotemporal (IT), temporalinferior (TI), temporalsuperior (TS), and superotemporal (ST) and perifoveal, parafoveal parameters were obtained in 4 different quadrants: temporal, nasal, inferior, superior. Results In PE+ eyes, the cpVD was significantly lower in all eight sectors (p
