Purpose
To evaluate the factors related to stereoacuity in children older than 7 years old when normal visual acuity was achieved and in whom school life was begun with refractive accommodative esotropia. Methods: We retrospectively reviewed the records of 42 children older than 7 years old with refractive accommodative esotropia. All clinical data were reviewed, including sex, time of onset, initiation time of spectacles correction, presence of anisometropia, amount of deviation with or without spectacles correction, history of occlusion treatment, fusion, and stereoacuity. Results: The mean age at the time of diagnosis of esotropia was 3.43±1.8 years, and the mean age of initiation time of spectacles correction was 3.35±1.71 years. The mean refractive error was 4.69±1.69 diopters. The amount of esodeviation with or without correction was 26.55±11.19 prism diopters (PD) and 1.33±0.56 PD, respectively. Stereoacuity was measured by Titmus stereotest at 20∼70 seconds of arc in 5 patients (11.8%), 100∼140 seconds of arc in 7 patients (16.7%), 200∼400 seconds of arc in 12 patients (28.5%), 3,000 seconds of arc in 7 patients (16.7%), and none in 11 patients (26.2%). The corrected visual acuities were 0.94±0.17 for the right and 0.92±0.13 for the left eye. Fusion measured by distant Worth four-dot test was present more often in the patients with orthotropia (77.8%) than in the patients with microtropia (22.2%) (p=0.481). At presentation, the presence of fusion was the only significant factor related to stereoacuity (p=0.026). Conclusions: The presence of fusion appear to be the only statistically significant factor related to stereoacuity in patients older than 7 years old with refractive accommodative esotropia.
