| Description: |
Purpose The aim of this study was to investigate the correlation between glaucoma and retinal vein occlusion (RVO) using quantitative metrics of vascular stasis on optical coherence tomography angiography (OCTA). Patients and methods This is a prospective observational, cross-sectional, case–control study that evaluated the retinal peripapillary venous tortuosity index (VTI), as a sign of vascular stasis, by using OCTA images. The study included 45 eyes of 45 patients who were equally distributed among three study groups: healthy controls (15 eyes), glaucomatous eyes with no RVO (15 eyes), and glaucomatous eyes with unilateral RVO (15 eyes). The OCTA scans were also evaluated to obtain the vessel density of the peripapillary and macular capillary plexuses for evidence of capillary nonperfusion. Results There was a statistically significant difference in the VTI among the three groups ( P |
