Safety and Outcome of Microincision Vitreous Surgery in Uveitis

Abstract

Purpose: To report the outcome of microincision vitreous surgery (MIVS) in uveitis.

Methods: In total, 103 patients (106 eyes) underwent diagnostic MIVS between March 2012 and April 2015. Postoperative evaluation included vitreous haze grading from clinical/electronic records, best-corrected visual acuity (BCVA), and complications.

Results: Mean age was 36.8 ± 13.9 years (range: 8-80 years). Mean follow-up after MIVS was 12.2 ± 7.2 months (median 12 months). Mean vitreous haze grading was 2.39 ± 0.98 (preoperatively), 0.36 ± 0.73 postoperatively (1 week), and 0.02 ± 0.2 at 1 month (p < 0.001). Mean BCVA was 1.5 ± 1.0 logMAR preoperatively and 0.72 ± 0.68 logMAR at 1 month (p = 0.000). Postoperative complications included cataract (14.6%), rise in intraocular pressure (13.2%), vitreous hemorrhage (4.7%), hypotony (3.2%), retinal detachment (2.8%), epiretinal membrane (2.8%), and worsening of inflammation (0.9%).

Conclusions: MIVS is safe and may have a therapeutic role in uveitis.
