When the degree of anisometropia was high, it was observed a major number of patients with severe amblyopia 22 (71.0%), and when it was low more patients without amblyopia were found 11 (33.3%). Regarding visual acuity: 17 (21.5%) were classified as great, 25 (31.6%) as better, 1 (1.3%) as worst and 11 (13.9%) unchanged.
