The CAM vision-stimulator treatment was given to 54 amblyopic children in TMCH during the past 6 years. They were divided into two groups, one composed of children 4-6 1/2 years old, the other composed of children 6 1/2-8 years old. The average number of treatment was 21, while, the average period of treatmeht was 5.2 months. There was no significant difference regarding improved V.A. between these two groups in the training periods of the 1st month, the 1st quarter, the 2nd quarter and the 3rd quarter (P＞.10, by student t-test). But both groups had a significant improvement of V.A. (P＜.05, by student t-test) in the 1st month, the 1st quarter and the 2nd quarter of the training periods. However, there was no significant improvement of V.A. in the 3rd quarter of list training period in both groups. 97% of the children in the younger guoup and 88% in the older group showed visual improvement of at least two lines on the Snellen chart. The main cause of their amblyopia was isoametropia. 88% of the children in the younger group and 95% in the older group were found to have isoametropia.
