A Case of Cyclic Esotropia after Psychological Trauma

Purpose: To report a case of cyclic esotropia after psychological trauma that resolved spontaneously without any surgical treatment. Methods: An 8-year-old boy developed blepharoptosis, limitation of abduction, and esotropia with headache and vomiting after psychological trauma. Brain MRI, cerebrospinal fluid examination, and EEG (electroencephalogram) showed no significant abnormalities. The ptosis and limitation of abduction were resolved gradually, but esotropia persisted in a cyclic pattern. Results: During follow-up, the 96-hour cycle of esotropia was gradually shortened to a 48-hour and then to 24-hour cycle. At final follow-up, the cyclic esotropia had disappeared completely and the patient has been orthotroric for more than 4 years. Conclusions: Cyclic esotropia may occur after psychological trauma and may resolved spontaneously without any surgical treatment.
