Exploring Perceptual Learning in Blurred Gabor Discrimination for Low-Myopic Children
Sponsor: National Taiwan University Hospital
Summary
This exploratory study investigates whether perceptual learning using blurred Gabor stimuli can improve uncorrected distance visual acuity in children aged 6-10 years with low myopia. Participants will be randomly assigned to a training group or control group. The training group will undergo individualized visual perceptual learning through a digital Vision Training System (VTS) for approximately 3 months. The study will also evaluate changes in refraction, contrast sensitivity, visual crowding, Chinese reading acuity with eye movements, and sweep visual evoked potentials (sVEPs).

Interventions
vision training system, VTS
Participants in this group will receive individualized visual perceptual learning using the Vision Training System (VTS). The training involves blurred Gabor stimuli presented via a computer-based application. Each participant will complete approximately 20 training sessions over 3 months, with each session lasting 15 to 30 minutes, conducted twice per week. The program is designed to enhance uncorrected visual acuity, contrast sensitivity, and other visual functions by engaging neural mechanisms related to perceptual learning. Training progression is adaptive based on individual performance. The VTS software was developed in collaboration with Bar Ilan University.
