Adie's tonic pupil-induced angle-closure glaucoma.

A 52-year-old woman was diagnosed as having Adie's tonic pupil in her right eye. She reported few episodes of blurring of vision in her right eye in the recent few months. On one of the routine follow-up visits, right intraocular pressure (IOP) was 70 mm Hg and on gonioscopy the angle was closed 360 degrees. Medical treatment resulted in IOP reduction and laser iridotomy was then performed. This is, to our knowledge, the first description of intermittent angle-closure glaucoma attacks induced by a tonic pupil. The possibility of angle-closure glaucoma should be considered in patients with a tonic pupil, especially with symptoms of blurred vision or ocular pain.
