RESUMO

Fifty-five patients with amblyopia in unilateral high myopia without strabismus were treated. Thirty-two (58%) had a visual improvement by two lines or more on the Snellen chart and 17 (31%) attained a final visual acuity of 6/12 or better. In patients with pretreatment corrected vision of 6/60 or better in the amblyopic eye treatment consisted of full-time occlusion of the good eye, in some cases supplemented by the after-image method of pleoptic exercises in the amblyopic eye. Overall improvement of vision in this group was 72.7%. Occlusion of the good eye combined with pleoptic exercises in the amblyopic eye had no advantage over simple occlusion of the good eye. In patients with pretreatment corrected vision worse than 6/60 in the amblyopic eye occlusion of the amblyopic eye was done and the after-image method of pleoptic exercises was instituted. Improvement of vision in this group was 36.3%. The study showed that it is worth the trouble to treat this disorder even after the age of 14 years and stresses the utility of pleoptic therapy in older patients with severe amblyopia.
