Introduction: Glaucoma is one of the most common complications in uveitis. The surgical intervention has been known for a lower success rate in Uveitis Glaucoma (UG). However, it is still a treatment of choice when medical therapy no longer could control the intraocular pressure (IOP). This study aims to describe UG's demographic and clinical characteristics that received glaucoma surgery and the outcome.
Methods: Medical records of UG patients that received glaucoma surgery in 2018-2019 were reviewed. Age, gender, type and etiology of uveitis, duration of uveitis, intraocular pressure (IOP), visual acuity, gonioscopy, ocular characteristic, previous surgery and laser, current surgery, and complication were studied. Success was defined as IOP ≤21 mmHg or reduction >20% from baseline and >6mmHg with or without medication. Failure is defined in the presence of surgery complication that leads to a change of IOP, uncontrolled IOP that needs additional surgery, and visual acuity becomes no light perception (NLP).
Results: 48 patients (57 eyes) with UG underwent glaucoma surgery. The mean age was 47,23±14,62. Anterior uveitis was the most common type of UG, with a mean uveitis duration before surgery was 13,75±17,65 months. The mean initial IOP was 35,81±13,30 mmHg, at the final visit 15,09±3,36. The mean follow-up duration was 6,41±4,02 months. The overall partial success was 75,44% in one month, 67,74% in 6 months
Conclusion: A decrease in IOP was found in all surgery interventions, including Glaucoma Drainage Device (GDD) implant, trabeculectomy with 5-Fluorouracil (5FU), and combined trabeculectomy cataract surgery with or without 5FU, and cyclodestructive laser surgery. There was a high percentage of successful surgery but many losses to follow-up eyes in a short follow-up period.
