Abstract
PURPOSE
We sought factors affecting amblyopia recurrence after successful treatment. METHODS: We included 117 patients with amblyopia. Patients were divided into recurrence and non-recurrence groups. We analyzed sex, age, amblyopia type, treatment duration, visual acuity, and binocular status. RESULTS: Of the 117 patients, 25 (21.4%) experienced recurrences. In that group, 60.0% of patients (compared to 14.1% of the no-recurrence group) exhibited high-frequency strabismus (p < 0.001). The recurrence group were younger than the no-recurrence group at both the beginning and end of treatment (p < 0.05). None of visual acuity at treatment commencement or end, stereoacuity, or suppression affected amblyopia recurrence. CONCLUSIONS: Recurrent amblyopia is frequent after initial successful treatment if the patient exhibits strabismus or is young.
