ABSTRACT

PURPOSE: To report the clinical presentations, neuroimaging findings, and surgical outcomes in patients with acute acquired non-accommodative comitant esotropia (AACE). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

ABSTRACT

PURPOSE: To evaluate the surgical outcome of augmented superior rectus transposition (SRT) and medial rectus recession (MRc) in patients with abducens nerve palsy. METHODS: The medical records of consecutive patients with abducens nerve palsy who underwent unilateral or bilateral simultaneous SRT with MRc from January 2012 to December 2014 were analyzed. Patients with previous strabismus surgery or botulinum toxin injection were excluded. Primary outcome measures were esotropia in primary position and abduction deficit. Data collected included age, sex, etiology, pre- and postoperative deviation, pre- and postoperative abduction deficit, anomalous head posture, induced vertical or torsional deviations postoperatively, reoperations, and details of other complications. Success was defined as postoperative alignment within 10Δ of orthotropia; failure, as residual esotropia of ≥20Δ. RESULTS: A total of 15 eyes of 13 patients were included. The most common cause of abducens nerve palsy was trauma (10 patients). The mean preoperative esotropia was 55.4Δ ± 24Δ, which improved postoperatively to 9.9Δ ±10Δ (P = 0.0000). The mean preoperative abduction deficit was -5 units, decreasing postoperatively to -3.1 (P = 0.000). Nine patients (69%) achieved success; 2 were classified as failures. One patient each developed postoperative hypotropia and intorsion; however, these were transient and did not require additional procedures. No patients developed anterior segment ischemia. CONCLUSIONS: Augmented SRT with MRc is effective in the management of abducens nerve palsy; however, its success in large deviations remains variable. Long-term follow-up is essential to determine the incidence of vertical and torsional deviations.
