PRECIS: Although this sample with glaucoma had preserved central vision, they presented worse reading performance compared with similarly aged controls. OBJECTIVE: To determine whether patients with glaucoma with preserved central vision have impaired reading performance compared with healthy controls. METHODS: A cross-sectional study of 35 patients with glaucoma and 32 similarly aged controls with visual acuity better than 0.4 logMAR in both eyes. Each participant had a detailed ophthalmological examination followed by a 5-chart reading performance test using a Portuguese version of the Minnesota Low Vision Reading Test (MNREAD). Correlation between reading performance (reading speed) and ocular parameters was investigated. RESULTS: Participants had an average age of 63.0±12.6 years. In the glaucoma group, mean deviation in the better and worse eyes was -6.29±6.36 and -11.08±0.23 dB, respectively. There was no significant difference in age, sex, rage, education, visual acuity, or systemic comorbidities between groups. Participants with glaucoma had significantly slower reading speeds, with an average of 83.2±25.12 compared with 102.29±29.57 words per minute in controls (P=0.006). Reading speed was slower for all 5 charts. Odds of glaucoma increased by 1.29 (95% confidence interval, 1.07-1.56; P=0.009) for each 10 words per minute decrease in average reading speed, with this relationship maintained after accounting for age, schooling, and visual acuity. CONCLUSIONS: Patients with mild to moderate glaucoma had worse reading performance compared with similarly aged controls, despite both having preserved central vision.
