Comparison of Methods for Determining the AC/A Ratio in Accommodative Esotropia

The two most commonly used clinical methods of determining a high AC/A ratio are: 1) the gradient method, and 2) the distance/near disparity method. Significant differences can be found not only between these two methods, but also in the different techniques for the gradient method alone. The purpose of our study is to compare the gradient method using +3.00 lenses for near and -3.00 lenses for distance, and the distance/near disparity...
