Abstract

Background: Previous studies of partially accommodative esotropia (PAET) have assessed factors requiring surgery and alignment outcomes. The purpose of the present study was to additionally evaluate stereoacuity in patients who required surgery for their nonaccommodative component. Methods: The medical records of consecutive patients with PAET who underwent bilateral medial rectus recession from April 1990 to July 2010 to treat the nonaccommodative component were reviewed retrospectively. Preoperative data included visual acuity, stereoacuity, cycloplegic refraction, deviation at distance and near, and age at surgery. The primary outcomes were stereoacuity and alignment. Results: A total of 84 patients were included. Stereopsis by the Titmus StereoTest was demonstrated in 51 (61%) by the final visit. The average follow-up time was 4.4 ± 2.8 years (range, 0.8-11.0 years). Fine stereopsis (100 arcsec or better) was appreciated in 29 patients (35%, 57% of those with stereopsis). Of those with residual esotropia, 11 (50%) demonstrated stereopsis, and 7 (32%) appreciated fine stereoacuity. No exotropic patient had stereopsis. There was a statistically significant correlation between age at time of surgery and stereopsis at 1 year (ρ = 0.233; P = 0.033) but not at the final visit (ρ = 0.106, P = 0.34). Of the 84 patients, 56 (67%) had a favorable alignment (within 10 Δ of orthotropia) at the final visit; 22 (26%) had residual esotropia; and 6 (7%) had consecutive exotropia. Conclusions: In this subset of esotropic patients who required surgery for their nonaccommodative component, favorable sensory outcomes can be achieved. Furthermore, favorable stereoacuity can be found even when there is a residual esodeviation.
