Abstract

Aim: To assess the reading speed of low vision patients using different types of low vision devices having same magnification power for reading purpose.

Study Design: Prospective, cross-sectional study.

Method: This study was done on 30 patients, who were visited to Shri C.H. Nagri eye hospital (Tertiary eye care) and diagnosed as a low vision patients were enrolled in this study. Objective and subjective refraction performed. Objective refraction with Retinoscopy and subjective refraction for distance with Log MAR chart and near with MN READ chart has been performed. Patients having low vision will be compared with different type of magnifiers having same magnification power in respect to patients reading speed and comfort level with the help of MNREAD acuity chart.

Result: 30 low vision patients were enrolled in this study, who visited tertiary eye care center, among mean age of patients including was 44.3 ± 23.8 (11 - 80) years. Out of 19 (63.33%) were male population and 11 (36.66%) female population.

In most of the patients, low vision was caused due to retinal detachment (17%), Age related macular degeneration (14%), Retinitis pigmentosa (14%), Macular dystrophy (14%), and coloboma (10%).The low vision device including spectacle magnifier, stand magnifier and hand held magnifier with same magnification power of 2.5x, 3x, and 4x. Mean near visual acuity was (0.6 - 1) and maximum reading speed was 156 ± 78.49 (100 - 500) with spectacle magnifier.

Conclusion: It was found that reading speed with spectacle magnifier was maximum in all visual acuity size.
