Abstract

BackgroundTo compare the therapeutic effects of surgery following prism adaptation test versus surgery alone in acute acquired comitant esotropia (AACE).MethodsA total of 46 patients with AACE were enrolled in this retrospective study. Among them, 26 patients underwent surgery following prism adaptation test (combination group) and 20 patients underwent surgery alone (surgery group). The following parameters were evaluated including success rate, distant and near deviation angles, visual function, and near stereoacuity.ResultsThere were no significant differences in success rate between the combination group and surgery group at post-treatment 12 months (96.15% vs. 90.00%, p > 0.05). The postoperative distant and near deviation angles in two groups were significantly lower than that before surgery (p < 0.05). In addition, the numbers of patients with stereopsis postoperatively in two groups were significantly higher than that before surgery (all p < 0.05). Moreover, the numbers of patients with stereopsis and central stereopsis in the combination group were significantly higher than that in the surgery group postoperatively. At post-treatment 12 months, one (3.85%) case recurred in combination group and three (15.00%) cases in the surgery group. No complications were observed in the two groups.ConclusionsBoth approaches had therapeutic benefit in AACE. Surgery following prism adaptation test had better treatment benefits than surgery alone in improving binocular function and reducing recurrence rate.

Baseline characteristics A total of 46 patients diagnosed with AACE were retrospectively analysed in this study

Summary

Introduction

To compare the therapeutic effects of surgery following prism adaptation test versus surgery alone in acute acquired comitant esotropia (AACE). Acute acquired comitant esotropia (AACE) is a rare type of esotropia that usually occurs in older children and adults [1]. It is classified into three types: 1) Swan type: esotropia due to monocular occlusion or loss of vision in one eye; 2) Burian-Franceschetti type: esotropia characterized by minimal hypermetropia and diplopia, often. The recurrence rate of the strabismus after botulinum toxin injection is high, requiring reinjection [10]. These disadvantages limit the widespread use of botulinum toxin in the treatment of strabismus
