Results of intensive CAM grating treatment in a strabismic amblyope.

CAM treatment was instituted for an 8-week period in a 10-year-old patient who failed to respond well to conventional amblyopia therapy. A small, consistent, statistically significant improvement in visual acuity was found. This improvement was attributed to a change in fixation locus and to practice effects, and not to spatial frequency/orientation-dependent "reactivation" of cortical neurons involved in the development of amblyopia.
