Quality of Life in Patients with Birdshot Chorioretinitis Aged 80 and Older.

PURPOSE

Birdshot chorioretinitis (BSCR) is an ocular HLA-related disease with variable clinical progression. We examine the quality of life (QOL) of BSCR individuals aged ≥80 years, providing insights into the long-term disease impact.

METHODS

We utilized data from the CO-BIRD cohort (ClinicalTrials.gov Identifier: NCT05153057) conducted at Hôpital Cochin in Paris, France, focusing on BSCR patients aged ≥80. The main outcome was vision-related QOL using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25). We used Spearman correlation to explore the impact of better BCVA and MD on the composite score, and the Wilcoxon test to evaluate specific visual symptoms' effects.

RESULTS

The study included 35 patients with a mean age of 83.9 ± 3.7 years, 74.3% of whom received systemic immunosuppression. The mean composite score was 58 ± 30, with a median of 75 (23-79). The lowest subscores were driving capacity (38 ± 38), mental health (49 ± 33), and role difficulties (50 ± 35), while the highest were for ocular pain (70 ± 25) and social function (70 ± 38). Decimal BCVA below 0.5 and MD below -6 dB were associated with lower subscores. BCVA and MD were strongly correlated with the composite score ( = 0.67). Symptoms of poor color and blurry vision were significantly associated with lower composite score ( < 0.005).

CONCLUSION

Most BSCR patients over 80 in our cohort maintained sufficient vision for daily activities. The high standard deviation and wide range of VFQ-25 results reflect the heterogeneity of visual outcomes among elderly BSCR patients.
