Abstract

PURPOSE
To evaluate the initial factors influencing successful final stereoacuity in patients with refractive accommodative esotropia.
METHODS
The charts of 48 refractive accommodative esotropia patients 2 years of age or older andassessed using the Titmus stereoacuity test were retrospectively reviewed. Hyperopic refractive error on post-cycloplegic refraction, age at first glasses, stereoacuity after refractive correction and amblyopia were categorized and evaluated as the factors influencing final stereoacuity.
RESULTS
The mean follow-up period was 43.51 +/- 30.02 months. The mean hypermetropia at the initial examination was 4.67 +/- 2.18 diopters (D), the mean age at first glasses was 48.09 +/- 20.22 months and the mean stereoacuity after refractive correction was 1243.75 +/- 1378.24 seconds of arc. The rates of successful stereoacuity at the final visit were 83.3% without amblyopia, 75.0% with mild amblyopia and 42.9% with moderate amblyopia which were statistically significant (p = 0.039). Hyperopic refractive error and age at first glasses were categorized as +1.0 to <3.0 D, +3.0 to <5.0 D, > or =+5.0 D and 2 to <4 years, 4 to <6 years and > or =6 years, respectively, and the rates of successful stereoacuity at the final visit were 83.3%, 66.7%, 61.9% (p = 0.362) and 71.4%, 75.0% and 54.5% (p = 0.334), respectively.
CONCLUSIONS
The amblyopia at the initial examination was significantly associated with the outcome of stereoacuity at the final visit in patients with refractive accommodative esotropia.
