Abstract
BACKGROUND AND OBJECTIVE:To compare duration and efficacy of the dexamethasone (DEX) intravitreal implant in vitrectomized (pars plana vitrectomy [PPV] group) and non-vitrectomized eyes (control group) with macular edema related to central retinal vein occlusion (CRVO).PATIENTS AND METHODS:Eyes that received the DEX implant for CRVO related to macular edema were included in a retrospective chart review. Outcomes measured were best-corrected visual acuity (BCVA) and central macular thickness (CMT)RESULTS:Fifteen eyes were included in the study. Eight of 15 eyes had prior vitrectomy. Mean BCVA was 20/160 in both groups. Baseline mean CMT was 550 microns (PPV group) and 556 microns (control group, Fifteen eyes were included in the study. Eight of 15 eyes had prior vitrectomy. Mean BCVA was 20/160 in both groups. Baseline mean CMT was 550 microns (PPV group) and 556 microns (control group, P= .70), and improved to 307.5 microns (PPV group) and 316.3 microns (control group) (P= .90) after implant. The BCVA was 20/125 (PPV group) and 20/200 (control group) (P= .60). Time to next procedure was similar in both groups.CONCLUSIONS:This retrospective study shows similar CMT reductions with DEX implant treatment for CRVO-related macular edema in vitrectomized and non-vitrectomized eyes.
