Objective: To assess the impact of diabetes on vision-related quality of life (VRQoL) among a sample of older African-Americans (AA) who have not had recent eye examinations. Methods: Baseline data were obtained on 187 AAs enrolled in a clinical trial to test the efficacy of a culturally-relevant, home-based intervention to increase rates of dilated fundus examinations. Participants were AA, ≥ 65, with type 2 diabetes, with no eye examination in the preceding year. Each subject completed a baseline assessment which included the National Eye Institute's previously validated Visual Functioning Questionnaire-25 (VFQ-25). Baseline scores were compared with previously published VFQ-25 scores of a sample with diabetic retinopathy and a sample of non-diabetic subjects without ocular pathology. Results: Subjects were older (73.7 vs. 59.3), primarily female (68.4% vs 35.9%) and African American (100% vs 10%) compared to the diabetic retinopathy study sample. However, subjects' mean VFQ-25 scores were within 5 points of 11 of the 12 VFQ-25 subscales. Some of which include general vision (65.8±17.1 vs. 69.5±17.4), near vision (76.1±21.9 vs. 75.8±21.7), distance vision (84.09±18.36 vs. 82.9±17.9), social functioning (91.0±16.3 vs. 93.9±12.9, mental health (78.13±21.79 vs. 77.2±21.3), and dependency (89.4±19.4 vs. 91.3±17.4). Compared to non-diabetics, subjects' mean scores were lower (i.e., worse) by ≥ 10 points on 7 of the 12 VFQ-25 subscales. Conclusions: Diabetes negatively impacts VRQoL. These findings point to the need for clinical interventions for African-American patients with diabetes who do not adhere to vision care guidelines to prevent visual impairment, reduce health care costs, and improve VRQoL.
