Clinical Profile, Neuroimaging Characteristics, and Surgical Outcomes of Patients With Acute Acquired Non-accommodative Comitant Esotropia.

Abstract

To report the clinical presentations, neuroimaging findings, and surgical outcomes in patients with acute acquired non-accommodative comitant esotropia (AACE). A retrospective review of records of all patients diagnosed as having AACE between January 2011 and December 2019 across three tertiary eye care centers was done. Cases with AACE onset after age 1 year were included. Patients were divided into two groups based on age of onset of esotropia: childhood (16 years or younger) and adult (older than 16 years). Surgical success was defined as postoperative horizontal deviation of 8 prism diopters (PD) or less at the last follow-up visit. A total of 338 patients (220 males and 119 females; mean age at presentation: 12.60 ± 9.8 years) met the study criteria. The mean age at onset of esotropia in the childhood and adult onset groups was 3.61 ± 1.1 and 26.6 ± 8.7 years, respectively. There were significantly more individuals with myopia (30%) in the adult onset group compared to the childhood onset group (6%) (P = .004). Thirty-seven (16%) had positive neuroimaging findings (16.4% adult onset vs 9.4% childhood onset). A total of 148 (44%) patients underwent surgery for esotropia, and the overall success rate was 73%. Mean preoperative esotropia was comparable in either group (P = .20), but surgical success was better in the adult onset group (75.6% vs 66.3% in the childhood onset group). Mean duration of follow-up postoperatively was 13.6 ± 12 months. Two-thirds of the patients had childhood onset of AACE. Intracranial pathology was found in 1 of 6 patients. Surgical success was better in the adult onset group, which was not influenced by preoperative esotropia, neuroimaging findings, or refractive status, but was dependent on age at onset of esotropia and duration between onset and intervention.
