PURPOSE: To describe differences in the clinical characteristics of birdshot retinochoroidopathy (BSRC) patients diagnosed early and later in life. METHODS: This is a retrospective cohort study. Age was primarily analyzed and 50 years of age at diagnosis was selected as a cut-off point. RESULTS: A total of 144 patients (288 eyes) were included; 68 with early-onset and 76 with late-onset BSRC. The younger group had a statistically significant higher rate of more severe iritis (p = 0.04); an average number of non-steroidal immunosuppressants and biologic agents (NSIB) (p = 0.04); and a prolonged time to initiation of NSIB (p = 0.01). There were only four patients (3%) who had >0.5+ cells in the anterior chamber. CONCLUSIONS: Patients with early-onset BSRC carried a higher risk for anterior segment inflammation, had a more prolonged delay to initiation of treatment with NSIB, and required a greater number of NSIBs to achieve remission.
