Characteristics and Outcomes of Glaucoma Associated With Congenital Ectropion Uvea.

PURPOSE

To determine the visual outcomes and effectiveness of glaucoma surgeries in congenital ectropion uvea.

DESIGN

Retrospective interventional case series.

METHODS

Surgeries and examination findings were collected on 11 eyes of 8 patients with congenital ectropion uvea at 2 academic sites from 2001 to 2021. Visual outcomes, surgical success (intraocular pressure [IOP]: 5-20 mm Hg, no additional IOP-lowering surgery, no visually devastating complications), and survival rates of glaucoma surgeries were assessed.

RESULTS

Glaucoma in bilateral congenital ectropion uvea was diagnosed at an earlier age (0.02 ± 0.01 years) than unilateral disease (8.9 ± 5.3 years, P = .002). All eyes required glaucoma surgery with 91% requiring multiple surgeries (3.5 ± 2.1, median 3 surgeries per eye). Trabeculotomy (8 eyes) showed 13% success rate. Although none of the 4 eyes that underwent trabeculectomy with mitomycin C needed repeat trabeculectomy, glaucoma drainage device placement, or cycloablation, 75% required bleb revision surgery. Glaucoma drainage devices (7 eyes) had a 57% success rate with 3 eyes requiring subsequent cycloablation (2) or trabeculectomy (1). At the final follow-up (8.5 ± 6.6 years, median: 7.9 years), all eyes achieved IOP control, and IOP was lower compared with presentation (13.2 ± 2.6 mm Hg vs 32.9 ± 9.9 mm Hg, P = .002). Best-corrected logarithm of the minimum angle of resolution visual acuity at the final follow-up was 0.2 ± 0.2.

CONCLUSIONS

Bilateral congenital ectropion uvea presents with glaucoma earlier than unilateral cases. The majority of eyes required multiple glaucoma surgeries. Angle surgery was less effective than trabeculectomy or glaucoma drainage devices. IOP control was obtained in all eyes and affected individuals had good visual outcomes.
