Abstract
Purpose: To report the pattern, epidemiology, and clinical features of anterior uveitis (AU) in southern TaiwanMethods: A prospective case series was performed to recruit patients with AU at two medical centers (Kaohsiung Chang Gung Memorial Hospital and Kaohsiung Veterans General Hospital) in southern Taiwan from December 1, 2018 to March 31, 2020. These patients enrolled were reviewed for clinical diagnoses, ocular presentations, and laboratory data, including aqueous polymerase chain reaction tests.Results: A total of 112 patients were included. The most common clinical diagnoses were idiopathic AU (37.5%), HLA-B27-associated acute AU (25.0%), and herpetic AU (18.8%); among herpetic etiology, cytomegalovirus (CMV) was the most common pathogen. Hypertensive AU was associated with older age, more males, and greater numbers of corneal edema, and fewer iris posterior synechiae. Compared with HLA-B27-associated acute AU, CMV AU was associated with older age, high intraocular pressure, more keratic precipitates, greater iris atrophy, more pseudophakia, and fewer pupil posterior synechiae. Conclusion: This prospective study identified the epidemiological and clinical features of AU in southern Taiwan. The most common etiologies were idiopathic AU, HLA-B27-associated acute AU, and herpetic (most CMV) AU.
