Analysis of the clinical features and surgical efficacy of acute acquired comitant esotropia

Abstract

Objective To analyze the clinical features and surgical efficacy of acute acquired comitant esotropia(AACE). Methods Clinical intact data of 25 patients with AACE who underwent strabismus surgery in Shanxi Ophthalmological Hospital from Sep. 2013 to May 2018 were analyzed retrospectively. Among them 20 patients underwent binocular visual function test. Different surgical procedures were designed, according to the objective and subjective esodeviations measured at near and distance. The efficacy was observed. Results There were 1 patient with hight hyperopia, 3 patients with emmetropia or mild hyperopia and 21 patients with myopia. The objective preoperative angle of deviation was (37±19) prism diopters(PD)at 33 cm and (42±19) PD at 6 m. There were 10 patients whose subjective esodeviations were 10 PD more than objective esodeviations and 15 patients whose subjective and objective esodeviations were equal. There were 19 cases with poor accommodative facility. Four patients underwent unilateral medial rectus recession, 2 patients underwent unilateral lateral rectus resection, and 19 patients underwent unilateral medial rectus recession and lateral rectus resection. All surgery succeeded. Conclusion Poor accommodative facility may be related to the onset of AACE. The combination of the objective and subjective esodeviations measured at near and distance is an effective method for the treatment of AACE.
