ABSTRACT
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.
Acknowledgments
Preliminary results from this work were presented at the fourth Birdshot Uveitis Day, November 2018, London. It was also accepted as poster presentations at the Association for Research in Vision and Ophthalmology 2020 Annual Meeting, and the Royal College of Ophthalmologists Annual Congress 2020 but could not be presented because of the COVID-19 pandemic.
