Low Vision Referral Patterns in Intermediate Age-Related Macular Degeneration.

Sparse data exist regarding low vision (LV) services referral patterns. We retrospectively examined our institution's intermediate age-related macular degeneration (iAMD) patients to determine factors influencing referral. We compared visual acuity (VA) and Visual Function Questionnaire (VFQ-25) composite and subscale scores for referred and non-referred iAMD patients. VA was collected at time of referral or most recent visit, and VFQ-25 was taken upon enrollment into the registry. Thirty-six (15.5%) of the 232 iAMD patients were referred to LV. Referred patients were more likely to have older age, worse VA in both eyes, and lower VFQ-25 scores. Univariate analysis of VFQ-25 subscales demonstrated worse scores in general vision, near, distance, mental health, role limitations, dependency, and driving. Multivariable analysis revealed lower scores in general health, general vision, and driving. Forty-eight percent of non-referred patients had VA or VFQ-25 composite scores at least as poor as the median for referred patients. Two-thirds of patients who were not referred had no discernable obstacle to referral. Our institution refers patients with worse objective and functioning vision, but more patients may benefit from referral. Future studies should identify metrics to prompt referral and evaluate this approach. [ABSTRACT FROM AUTHOR]
