Abstract
AIM: The aim of this study is to determine the outcome of accommodative esotropia (ET) and influencing factors in young Omani children. SUBJECTS AND METHODS: In this retrospective cohort, children diagnosed with accommodative ET who had followed up in a tertiary hospital from 2006 to 2011 were identified. Parameters studied included cycloplegic refraction and its change with time, ocular alignment, binocularity, visual acuity (VA), amblyopia, and requirement for surgery. RESULTS: A total of 51 patients were identified. Twenty-four patients were diagnosed with fully accommodative ET (FAET) and 27 with partially accommodative ET (PAET). The mean (± standard deviation [SD]) age of onset and reporting were 2.6 (±1.58) and 3.2 (±1.84) years in the two groups, respectively. The mean (SD) cycloplegic refraction at presentation was 4.50 (±1.66) in the FAET group and 3.65 (±1.67) in the PAET group. Anisometropia was present in 28% of patients. The mean follow-up period was 4.9 years. The following were detected in the final visit. A reduction in amblyopia from 43% to 6% of patients, binocularity in 75% of patients, and a mean increase of 0.64 (±1.3) D in cycloplegic refraction from the first visit (P = 0.005). The mean angle of deviation at near and distance was 29.86 (±15.21) and 17.80 (±10.14) prism diopters, respectively, in FAET patients and 30.15 (±14.83) and 29.53 (±15.53), respectively, in PAET patients. Thirty-seven percent of the PAET patients underwent surgery within 5 years from diagnosis. All participants in this cohort continued to wear glasses in the last follow-up visit. CONCLUSION: Most children with refractive accommodative ET have an excellent outcome in terms of VA and binocular vision. The PAET group was characterized by delayed reporting, the presence of anisometropia, and lower hypermetropia. Further study is required to determine the possibility of weaning glasses in FAET patients.
