title: Relationship between vision-related quality of life and different types of existing visual fields in Japanese patients.
abstract: To investigate the vision-related quality of life (VRQOL) in relation to the type of existing visual field (EVF) in the presence of visual field defect. We evaluated the VRQOL of 95 patients by using Visual Function Questionnaire-25 (NEI VFQ-25). Patients fulfilled the following criteria: (1) they underwent a Goldmann perimetry (GP) test within 3 months of the initial visit, (2) the results of the GP test could be classified into three categories, and (3) the best-corrected decimal visual acuity (VA) was ≤0.3. The EVF was assessed by composite measurement of both eyes for the V-4e or I-4e isopters, as obtained using the GP test. We compared the VFQ-25 scores between three groups: (1) the "center and peripheral" group in which the EVF of the V-4e area was >30º and the I-4e area was <30º, (2) the "central VF" group in which the EVF of the V-4e area was <20º, and (3) the "central VF loss" group in which the central scotoma was >5º and the EVF of the V-4e area was >30º in peripheral vision. There were significant differences between the three groups (P = 0.02, ANOVA). The total score of the "central VF loss" group was significantly lower than those of the "center and peripheral" and "central VF" groups. The central vision influenced the VRQOL to a greater extent than peripheral vision.
