Creating a Health Utility Value for Birdshot Chorioretinopathy

Purpose To create a health utility value for birdshot chorioretinopathy (BCR) using Time Trade-Off (TTO) and Standard Gamble (SG) utilities. Method Adult BCR patients completed TTO, SG, EQ-5D-5L, and NEI VFQ-25 questionnaires and underwent a detailed history and clinical examination. Results A total of 28 BCR patients (9 M, 19 F; mean age 62 years, range 47-83) were included. There were 22 patients with a logMAR vision of 0.3 or better in both eyes. Mean TTO was 0.90 +/- SD 0.18 (range 0.33-1.0) and mean SG was 0.94 +/- SD 0.14 (range 0.5-1.0). TTO correlated with EQ-5D-5L index value (p= .024) and NEI VFQ-25 composite score (p= .015). Conclusions Of 28 patients with BCR, 11 would trade remaining life (mean 5.4 years), and 6 would take a risk of immediate death (mean 28% risk), in return for perfect vision in both eyes for the rest of their life.

Automated summary

A health utility value for BCR was created using TTO and SG utilities. The study found that among 28 BCR patients, 11 were willing to trade their remaining life for perfect vision and 6 were willing to take the risk of immediate death for perfect vision.
