Purpose: To investigate the incidence and risk factors for developing ocular hypertension or glaucoma needing treatment among uveitis patients in Taiwan. Methods: The nationwide database-derived retrospective cohort study was designed using Taiwan's National Health Insurance Research Database. From 1 million representative samples randomly selected from the beneficiaries of the National Health Insurance program, all patients with a diagnosis of uveitis were identified. Only newly onset uveitis patients who were diagnosed after January 1, 2002 and had no prior diagnosis of glaucoma were included in the study, and were followed up until December 31, 2008 or the last day that they were covered by the program. A patient was defined as having glaucoma as soon as both a diagnosis of glaucoma or ocular hypertension as well as a claim for medical or surgical treatment of glaucoma was found. Risk factors for developing glaucoma at the time of, or after the uveitis incidence were evaluated and discussed. Results: Initially, 5757 newly diagnosed uveitis patients were enrolled in the study. Of these patients, 488 (8.5%) were also diagnosed with glaucoma at the time of uveitis incidence. Patients aged 17 to 64 years, of male sex and diagnosed with anterior uveitis were more likely to have glaucoma at the time of the uveitis incidence. Among the remaining 5269 patients, 351 (6.7%) patients developed glaucoma during the follow-up period. Significant risk factors included increasing age, having been diagnosed with anterior uveitis, having more than an average number of ophthalmic claims within the first 3 months, and complications with corneal edema. A stratified analysis showed that having a history of receiving intraocular surgery is also a risk factor for the development of glaucoma among adult patients. Conclusions: The development of glaucoma in uveitis patients is noteworthy and is associated with several demographic and clinical factors. To minimize the visual impairment caused by uveitis-related glaucoma, clinicians should pay more attention to those uveitis patients who are at high risk for developing glaucoma.
