BACKGROUND: The purpose of this study was to assess visual function and vision-related quality of life after intravitreal injection of ranibizumab (IVR) using a pro re nata regimen for the treatment of age-related macular degeneration. METHODS: A prospective study of 54 eyes in 54 patients scheduled to undergo IVR for the treatment of exudative age-related macular degeneration was performed. A self-administered, 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was completed before and 3 and 12 months after the initial IVR treatment. We evaluated logMAR visual acuity and NEI VFQ-25 scores preoperatively and postoperatively. Further, associations between the changes in NEI VFQ-25 scores and patient characteristics were investigated at 12 months. RESULTS: Postoperative best-corrected visual acuity improved significantly when compared with the preoperative visual acuity throughout the 12-month period (P<0.05 at 3 and 12 months, respectively). On the other hand, IVR treatment significantly improved the postoperative NEI VFQ-25 mean composite score at both 3 and 12 months (P<0.05, respectively). Better visual acuity at 12 months was associated with a greater improvement in NEI VFQ-25 score at 12 months (P<0.05). CONCLUSION: IVR was well tolerated and improved vision in these patients with age-related macular degeneration, as evaluated at one-year follow-up examinations. IVR also enabled good subjective perception, as indicated by higher composite NEI VFQ-25 scores. Maintaining good visual acuity may be an important factor for improving vision-related quality of life.
