[Unilateral cystoid macular edema induced by citalopram--a case report].

Citamopram is an antidepressant drug with fatigue, sleep disorders, appetite changes and visual impairment being the most common side effects. We are not aware of any published cases of cystoid macular edema following medication of this drug. We present a case of 55 year old woman with medical history of depression placed on Citalopram medication who noticed deterioration of right eye vision. Best corrected visual acuity was 20/120, ophthalmic coherence tomography and fluorescein angiography revealed cystoid macular edema. Two months following drug withdrawal edema disappeared and best corrected visual acuity improved to 20/32. Due to lack of other probable causes of edema and quick disappearance following drug withdrawal it is plausible to think of Citalopram as causative factor of cystoid macular edema in this patient.
