PURPOSE
To investigate the relationship between dominant eye and refractive error in patients with myopic anisometropia. METHODS: This study population consisted of myopes less than 15 years old who were followed up for anisometropia defined as interocular difference of spherical equivalent (SE) ≥1.0 diopter (D). All patients underwent the hole-in-the-card test at far and near to determine ocular dominance. The data were analyzed for statistical significance using Fisher's exact test. RESULTS: A total of 102 eyes in 51 patients were analyzed. The mean age of the patients was 10.4 ± 1.4 years and 54.9% were male. The mean SE was −2.97 ± 1.95 D in the right eye and −3.02 ± 1.92 D in the left eye. The right eye was the dominant eye in 43.1% and 37.3% at distance and near, respectively. The agreement of dominancy between distant and near was 82.4%. The near dominant eyes showed statistically significant accordance with more myopic eyes (p = 0.009). On the other hand, there was no statistically significant relationship between more myopic eyes and distant dominant eyes (p = 0.09). CONCLUSIONS: The near dominant eye was more myopic eye in patients with myopic anisometropia. This was considered to be related with the lag of accommodation in dominant eye with near distance. |
