Bilateral acute angle closure after venlafaxine intake in a young patient with a narrow iridocorneal angle.

We report a case of bilateral and acute angle closure after a single dose of antidepressant venlafaxine in a 40-year-old woman with no previous pathologies, who asked for consultation for blurred vision and pain in the left eye. Initial evaluation included visual acuity, slit lamp biomicroscopy and intraocular pressure (IOP) measurement using Goldmann's applanation tonometer. Gonioscopy and fundus examination were also performed in both eyes. Examination and IOP supported the diagnosis of acute glaucoma in the left eye. The patient's evolution was satisfactory after bilateral peripheral iridotomy was performed with Nd-YAG laser, as described in the cases reported in the international literature. The pathophysiology of angle closure and its relationship with venlafaxine intake were also discussed.
