PURPOSE: To report the effectiveness of the vertical monocular displacement of the horizontal rectus muscles, proposed by Goldstein, in esotropic patients with A pattern, without oblique muscle overaction. METHODS: A retrospective study was performed using the charts of 23 esotropic patients with A pattern > 10delta, submitted to vertical monocular displacement of the horizontal rectus muscles. The patients were divided into 2 groups in agreement with the magnitude of the preoperative deviation, group 1 (11delta to 20delta) and group 2 (21delta to 30delta). Satisfactory results were considered when corrections A < 10delta or V < 15delta were obtained. RESULTS: The average of absolute correction was, in group 1, 16.5delta and, in group 2, 16.6delta. In group 1, 91.6% of the patients presented satisfactory surgical results and in group 2, 81.8% (p = 0.468). CONCLUSION: The surgical procedure, proposed by Goldstein, is effective and there was no statistical difference between the magnitude of the preoperative anisotropia and the obtained correction.
