Purpose: To investigate the relationship between methods used to evaluate the visual field (VF) and vision-related quality of life (VRQOL) in Japanese patients. Methods: We evaluated the VRQOL of 50 patients using the National Eye Institute Visual Function Questionnaire 25 (VFQ-25). Patients meeting the following criteria were assessed: (1) a Goldmann perimetry (GP) test conducted within 3 months of the initial visit; (2) best-corrected decimal visual acuity (VA) of the better eye when VRQOL was measured was less than 0.3 but more than 0.05. The VF was estimated based on a composite measure of the V-4e isopters of both eyes, as measured by GP. We calculated the VF using the American Medical Association (AMA) score, the Esterman disability score (EDS), the functional field score (FFS), the composite VF area calculated with area measurement software, and SR, an evaluation method based on solid angles. We then studied the relationships between the VFQ-25 score and the VF scores. Results: Only EDS correlated significantly with the VFQ-25 score (r = 0.34, P = 0.02); AMA scoring did not correlate with the VFQ-25 score. Conclusion: It is necessary to reexamine standard VF evaluation methods.
