Birdshot Chorioretinitis in Patients Aged 80 and Older.

ABSTRACT

PURPOSE: To assess the manifestations of birdshot chorioretinitis (BSCR) in patients aged 80 and over. DESIGN: Among patients with BSCR followed in the CO-BIRD prospective cohort (ClinicalTrials.gov Identifier NCT05153057), we analyzed the subgroup of patients aged 80 and over. METHODS: Patients were assessed in a standardized manner. Confluent atrophy was defined as hypoautofluorescent spots on fundus autofluorescence (FAF). RESULTS: We included 39 (8.8%) of the 442 enrolled CO-BIRD patients. The mean age was 83.8 ± 3.7 years. The mean logMAR BCVA was 0.52 ± 0.76, with 30 patients (76.9%) having 20/40 or better in at least one eye. Thirty-five (89.7%) patients were receiving no treatment. Confluent atrophy in the posterior pole, disrupted retrofoveal ellipsoid zone and choroidal neovascularization were associated with logMAR BCVA >0.3 (p < .0001). CONCLUSION: In patients aged 80 and over we observed a striking heterogeneity of outcomes, but most retained a BCVA that allowed them to drive.
