Abstract. Purpose:To report the potential usefulness of iPad2® as a low-vision aid. Cases and Method:This study was made on 13 patients who were attending our Low-Vision Care Center. The series comprised 4 males and 9 females. The age ranged from 29 to 86 years,average 63 years. Visual disability was due to diabetic retinopathy 5 cases,retinitis pigmentosa 2 cases,macular degeneration 2 cases and others 4 cases. Bilateral visual acuity was less than 0.1 in 5 cases and 0.2 in 4 cases. With iPad2® as image-magnifying video system,patients were evaluated regarding maximum reading speed and critical print size using MNREAD-J charts. They were questionnaired about the system as low-vision aid. Results:Use of iPad® resulted in improved reading speed and critical print size. Patients expressed more comfort than reading with conventional hand-held magnifier. Conclusion:iPad2® promises to be of value as a reading aid for low-vision patients.
