Perceptual learning with hand - eye coordination as an effective tool for managing amblyopia: A prospective study

Abstract

Purpose: Amblyopia is a serious condition resulting in monocular impairment of vision. Although traditional treatment improves vision, we attempted to explore the results of perceptual learning in this study.

Methods: This prospective cohort study included all patients with amblyopia who were subjected to perceptual learning. The presenting data on vision, stereopsis and contrast sensitivity were documented in a pretested online format, and the pre- and post-treatment information was compared using descriptive, cross-tabulation and comparative methods on SPSS 2.2. The mean values were obtained, and P < 0.05 was considered statistically significant.

Results: The cohort consisted of 47 patients (23 females and 24 males) with a mean age of 14.11 ± 7.13 years. A statistically significant improvement was detected in visual acuity after the perceptual learning session, and the median follow-up period was 17 days. Also, significant improvements were observed in stereopsis but not in the visual outcomes among the age groups.

Conclusion: Perceptual learning with hand-eye coordination is an effective method for managing amblyopia. This approach can improve vision in all age groups. However, visual improvement is significantly influenced by ocular alignment.
