Abstract

Purpose
To compare the long-term clinical outcomes of patients with refractive accommodative esotropia (RAET) and infantile esotropia (IET).
Methods
The medical records of patients with RAET and IET who were followed-up for more than 36 months were retrospectively analyzed. The RAET patients were prescribed spectacles to correct cycloplegic refraction and those with IET underwent bilateral, medial rectus recession. Visual acuity, refraction, the angle of esodeviation at far and near distances, and near-stereopsis were measured at each visit. The IET patients were divided into two groups by the time of surgery (before and after 24 months of age). Patients in both groups who underwent reoperations after diagnosis of partially accommodative esotropia (PAET) and recurrent IET during follow-up were analyzed.
Results
Sixty-nine patients (40 with RAET and 29 with IET) were included. The follow-up period was 69.48 ± 28.41 months. At the final visit, the angles of esodeviation were 2.82 ± 5.46 prism diopters (PD) in the RAET group and 9.28 ± 8.37 PD in the IET group (p < 0.01). In IET patients who underwent surgery before and after 24 months of age, the angles of esodeviation were 4.62 ± 5.25 and 13.06 ± 8.63 PD and the median near-stereopsis values 60 and 140 arcsec at the final visit (p < 0.01, 0.03). Seven patients (17.5%) in the RAET group, and 2 (15.4%) and 10 (62.5%) IET patients who underwent surgery before and after 24 months of age, required reoperations (p < 0.01).
Conclusions
RAET and IET patients who underwent surgery before 24 months of age exhibited better alignment and stereopsis at the final visit than those who underwent later surgery and the reoperation rate was lower.
