Purpose: The purpose of this case series is to describe the efficacy of the EX-PRESS shunt in uveitic glaucoma.
Methods: This prospective case series sequentially recruited uveitic glaucoma subjects with intraocular pressure (IOP) > 21 mm Hg despite maximal topical antiglaucoma medications from July 2012 to July 2013 in Hong Kong. All subjects received a trabeculectomy with mitomycin C (MMC) and EX-PRESS shunt implantation. The primary outcome measures included preope-rative IOP and postoperative IOP on day 1, 1 week, 1 month, and every 3 months thereafter. The secondary outcome measures included postoperative complications and follow-up procedures, pre- and postoperative Snellen best corrected visual acuity and cup-disc ratio, as well as the number of antiglaucoma medication required.
Results: In a case series of five subjects with uncontrolled uveitic glaucoma, two had inactive anterior uveitis, and three had active panuveitis. The mean preoperative IOP was 35.4 ± 12.6 mm Hg on 3.8 ± 0.5 antiglaucoma eye drops. The mean day 1, 1 week and 1 month IOP\'s were 6.6 ± 3.7 mm Hg, 7.2 ± 3.2 mm Hg, and 12.6 ± 8.2 mm Hg, respectively. One case required subconjunctival MMC injections postoperatively; two required conjunctival resuture for leakage; and two had early postoperative hypotony that resolved after oral prednisolone. At 6 months, the mean IOP was 13.2 ± 4.6 mm Hg. Four out of five subjects had IOP < 21 mm Hg without medication, and all had IOP < 21 mm Hg with antiglaucoma medication.
Conclusion: The EX-PRESS shunt demonstrates good IOP control with a propensity for hypotony in the early postoperative period in this small uveitic glaucoma series.
