More patients had straight eyes in primary position than esotropia or exotropia. On lateral version reflex testing the amount of underaction of the lateral and medial rectus muscles could be determined, and could be used to predi...

The rate distortion optimization framework has been widely used in optimizing the performance tradeoffs. One fundamental issue involved is the difficulty in estimating the rate-distortion relationships under di...
