Purpose
To evaluate the changes in quality of life in noninfectious uveitis patients treated with two of the most commonly prescribed antimetabolite treatments.
Design
Secondary analysis of a multicenter, block-randomized, clinical trial (ClinicalTrials.gov NCT01232920).
Methods
Eighty patients at Aravind Eye Hospitals in Madurai and Coimbatore, India, with noninfectious intermediate, posterior, or panuveitis were randomized to receive oral methotrexate, 25 mg weekly, or oral mycophenolate mofetil, 1 g twice daily, and were followed up monthly for 6 months. Best-corrected visual acuity, IND-VFQ, and SF-36 were obtained at enrollment and at 6 months (or prior in the event of early treatment failure).
Results
IND-VFQ scores, on average, increased by 9.2 points from trial enrollment to 6 months (95% CI: 4.9, 13.5, P =0.0001). While the SF-36 physical component summary score did not significantly differ over the course of the trial, the mental component summary score decreased by 2.3 points (95% CI: −4.4, −0.1, P=0.04) and the vitality subscale decreased by 3.5 points (95% CI: −5.6, −1.4, P=0.001). Quality of life scores did not differ between treatment arms. Linear regression modeling showed a 3.2 point improvement in IND-VFQ score for every 5 letter improvement in visual acuity (95% CI: 1.9, 4.3; P<0.001).
Conclusions
Although uveitis treatment was associated with increased vision and vision-related quality of life, patient-reported physical health did not change after 6 months of treatment, and, mental health decreased. Despite improved visual outcomes, uveitis patients receiving systemic immunosuppressive therapy may experience a deterioration in mental health-related quality of life.
