Abstract
Purpose: To investigate the incidence and risk factors of secondary glaucoma among uveitis patients.Methods: Retrospective review of medical records of 642 patients (1220 eyes).Results: Glaucoma was diagnosed in 169 (13.9%) eyes and was most common in eyes with anterior uveitis (19.1%) (p<0.001). HLA-B27-positive anterior uveitis (27.6%), Fuchs' uveitis (23.3%), juvenile idiopathic arthritis (23.1%), herpetic uveitis (20.3%), and Vogt-Koyanagi-Harada disease (16.3%) were the leading clinical entities associated with glaucoma (p<0.001). Significant risk factors at presentation included worse visual acuity, elevated intraocular pressure, keratic precipitates, granulomatous inflammation, anterior chamber reaction2+, posterior synechiae, and cataract. Female gender and iris nodules significantly predicted the need for glaucoma surgery. Visual outcome was worse in eyes with glaucoma than in eyes without glaucoma.Conclusions: Incidence of glaucoma differed depending on anatomic and etiologic diagnoses of uveitis. There is a significant association between severity of inflammation at presentation and development of glaucoma.
