Abstract

PRECIS: At 1-year postoperative follow-up, concurrent placement of a dexamethasone intravitreal implant and glaucoma drainage device effectively controlled intraocular pressure (IOP) and inflammation in eyes with uveitic glaucoma with no changes in systemic immunomodulatory therapy. PURPOSE: The purpose of this study was to assess 1-year postoperative outcomes in eyes with uncontrolled uveitic glaucoma following concurrent placement of a dexamethasone intravitreal implant and glaucoma drainage device. MATERIALS AND METHODS: This is a retrospective, observational case series of patients with chronic, noninfectious uveitis and uveitic glaucoma uncontrolled on maximal tolerated medical therapy with at least 1-year postoperative follow-up. The main outcomes were visual acuity, IOP, number of glaucoma medications, recurrent inflammation, frequency of topical steroids, systemic immunomodulatory therapy, and adverse events. Success was defined as IOP <21 mm Hg and IOP reduced by >20% from baseline on at least 2 consecutive visits after 3 months either with or without glaucoma medications (ie, partial or complete success, respectively). RESULTS: Eight eyes in 6 patients met the inclusion criteria. The average age was 44.1±19.7 years (range: 10 to 68 y) and 50% were female. At 1-year, there was no significant change in visual acuity. No eyes lost ≥3 lines of vision. The majority of eyes (87.5%) achieved complete (n=2) or partial success (n=5) with a decrease in average IOP from 36.5 to 11.8 mm Hg (P=0.002). Glaucoma medication use decreased from 3.0 to 1.3 medications (P=0.04). There was a significant decrease in the number of episodes of recurrent inflammation in the 6 months following surgery compared with the 6 months before surgery (P=0.004). CONCLUSION: In this small case series, dexamethasone intravitreal implant combined with Ahmed glaucoma drainage device appears to be an effective approach for the management of uncontrolled uveitic glaucoma.
