Abstract:
ObjectiveTo compare balance-confidence among patients with primary open-angle glaucoma, age-related macular degeneration, and controls in Brazil.DesignCase-control study.SettingCharity hospital in São Paulo, Brazil.ParticipantsPatients with glaucoma, age-related macular degeneration, and controls without eye diseases.Main outcomes measuresActivities-specific Balance Confidence (ABC) Scale scores.ResultsThe sample consisted of 64 patients with glaucoma, 60 with age-related macular degeneration, and 60 controls. All groups were matched by age, gender, ethnic distribution, and comorbidities. The ABC Scale score was 63.1 (25.9) in the glaucoma group, 69.5 (16.4) in the age-related macular degeneration group, and 95.3 (9.1) for the controls (P < 0.001; Hedges' g -1.65 and -1.93, large effect size); glaucoma patients score did not differ from age-related macular degeneration patients (P = 0.132; Hedges' g 0.30, small effect size).ConclusionBoth glaucoma and age-related macular degeneration patients reported lower balance-confidence in performing daily activities without losing balance as compared to controls.
