Background:  Diplopia, or double vision, is a common ophthalmologic complaint with many underlying causes, ocular and neurological. Aripiprazole has been reported to have fewer adverse effects and better efficacy than other atypical antipsychotics. Although ocular side effects of aripiprazole are not remarkable, two cases of diplopia associated with aripiprazole have been reported in the literature.
Objectives: Herein, we report the third case of diplopia, after the aripiprazole prescription in a woman with depressive disorder.
Case Presentation: A 37-year-old woman was brought to our clinic with symptoms of sleep loss, displeasure, auditory hallucination, and pessimistic thoughts. After a clinical interview, the patient was diagnosed with depression with psychotic features according to the Diagnostic and Statistical Manual (DSM-V) of mental disorders. She underwent treatment with 15 mg/d aripiprazole and 20 mg/d fluoxetine. Her symptoms reduced after three months as indicated by the visual analog scale. However, the patient returned to the clinic and complained of double vision. Neither neurological nor ophthalmological problems were observed following examinations by specialists. When the dose of the drug decreased and eventually discontinued, diplopia disappeared over 24 hours.
Conclusion: Since the patient had no history of diplopia and two cases of diplopia associated with aripiprazole were previously reported in the literature, we expected that the diplopia was related to the recently prescribed aripiprazole treatment. Physicians should be aware of the possible risk of diplopia-induced by aripiprazole and recommend patients discontinuing the drug immediately if complications have occurred.
