    Abstract:
    PURPOSE: To describe vision-targeted health-related quality of life (HR-QOL), measured with the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25) in a cohort of patients with macular telangiectasia (MacTel) type 2 and to evaluate the relationship between visual acuity and NEI-VFQ-25 scores. METHODS: This was an analysis of cross-sectional baseline data from a longitudinal natural history study. Patients with MacTel type 2 were enrolled in the Natural History Study of The Macular Telangiectasia Project (The MacTel Project). NEI-VFQ-25 were completed at enrollment. Linear correlation and regression analyses were used to relate baseline NEI-VFQ-25 overall and subscale scores to visual acuity. RESULTS: Participants reported lower vision-related functioning measured by the NEI-VFQ-25 in most of the domains measured by the NEI VFQ compared with that of a normal reference group (P < 0.001 for all domains except color vision). Visual acuity was found to be associated with the NEI-VFQ-25 in many of the domains measuring degree of difficulty with common visual activities. CONCLUSIONS: This is the first cross-sectional cohort study to assess vision targeted HR-QOL in patients with MacTel type 2. Patients with MacTel type 2 reported markedly reduced visual functioning compared to reports of a normal reference group. These findings provide support to the use of the NEI-VFQ-25 in patients with MacTel type 2 to measure the effect of disease and potential therapies on vision-targeted HR-QOL.
