Visual functioning and general health status in patients with uveitis.

OBJECTIVE: To measure the visual functioning and quality of life in patients with uveitis.
METHODS: Consecutive adult patients with noninfectious uveitis were enrolled. The Medical Outcomes Study 36-Item Short Form (SF-36) and the National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) were administered by a trained interviewer. Sociodemographic and clinical data were also collected.
RESULTS: Seventy-six patients were enrolled. The overall NEI VFQ-25 score was significantly lower among patients with uveitis than in a normal reference group (P<.001). The SF-36 physical (PCS) and mental (MCS) component summary scores were also significantly lower among patients with uveitis than in the general US population (P<.007). Among patients with uveitis, visual acuity, binocular involvement, intensity of therapy, employment status, and PCS and MCS scores were all significantly associated with overall NEI VFQ-25 scores in multivariable analysis. Medical comorbidity, ocular comorbidity, and NEI VFQ-25 scores were significantly associated with PCS scores. Medical comorbidity and NEI VFQ-25 scores were significantly associated with MCS scores. Regression models including NEI VFQ-25 scores explained an additional 7% of the variance in PCS scores and 16% of MCS scores. Models including both PCS and MCS scores explained an additional 12% of the variance in NEI VFQ-25 scores.
CONCLUSIONS: Patients with uveitis reported markedly poorer visual functioning and general health status than normal subjects. Patients with more severe uveitis have poorer visual functioning and general health status than patients with milder disease. Visual functioning and general health status measurement contribute complementary information and should both be performed in patients with uveitis to measure the effect of disease and its therapy on their quality of life.
