Visual acuity and binocularity in unilateral high myopia.

Thirty-eight patients with unilateral high myopia ranging from 5 to 19 diopters were followed up for a median of two years. All were treated with full-spectacle correction and most had occlusion. When initially examined one patient (3%) had visual acuity of 6/12 (20/40) or better, four patients (12%) had central fusion, and 24 patients (63%) were phoric. At the conclusion of the study 12 patients (32%) had visual acuities of 6/12 (20/40) or better, 17 patients (45%) had central fusion, and 29 patients (76%) were phoric. Age at the start of treatment was not a factor in the versely affect the response to amblyopia was inversely related to both final fusion and final visual acuity.
