Abstract:
PURPOSE: To compare the surgical outcomes of functional equator-considering and Parks' methods in infantile esotropia and partially accommodative esotropia. METHODS: The medical records of 96 patients with infantile esotropia and partially accommodative esotropia who underwent bilateral medial rectus muscle recession by functional equator-considering and Parks' methods were reviewed retrospectively. The surgery success rate at 1 month, 3 months, 6 months and 12 months was compared by the deviation angle measurement. RESULTS: Overall success rates were not statistically different between the 2 groups. Additionally, there were no differences in surgical success rate of functional equator-considering and Parks' methods in infantile esotropia and partially accommodative esotropia. When the patients were divided into 2 groups based on 40 PD, no significant difference in success rate between the 2 groups was observed. When patients were divided into 2 groups based on 22 mm of axial length, there was no statistical difference observed. Postoperative overcorrection was 2 (4%) in the functional equator group and 3 (6.5%) in Parks' method group and postoperative undercorrection was 9 (18%, 19.6%) in each group. The incidence of undercorrection in the Parks' method group was significantly higher in the greater than 22 mm axial length group (7, 35.0%) than in the less than 22 mm group (2, 7.7%) (p = 0.029). CONCLUSIONS: There was no statistically significant difference in surgical success rate between the functional equator and Parks' methods in infantile esotropia and partially accommodative esotropia.
