Abstract:
Purpose: To evaluate a dose-response relationship by using Yokoyama procedure we compared a group of inhomogeneous cases with esohypotropia (EHT) associated with high myopia. Methods: We did a retrospective analysis of 7 cases with EHT associated with high myopia, who underwent Yokoyama procedure between 2014 and 2015. Pre- and postoperative orthoptic measurements as well as measurements of axial length were recorded. Results: The average age ranged from 59.5 ± 2.8 (SD) years. The mean value of axial lengths was 32.7 ± 3.2 mm (29-36.4 mm). The angle of esotropia changed from 44.6 ± 35.2 prism dioptres (PD) to 11.4 ± 16.9 PD and the angle of hypotropia changed from 15.4 ± 4.7 to 2.2 ± 5.2 PD postoperatively. All patients underwent Yokoyama procedure with fornix incision, 3 patients with additional medial rectus recession. Abduction and supraduction improved after surgery. The average follow-up was 6 months, the postoperative outcomes were stable. Conclusion: The Yokoyama procedure with or without additional medial rectus recession is an effective surgical treatment of EHT associated with high myopia.
