[Bilateral recurrent blurred vision associated with halos around sources of light and headache].

A 21-year-old male presented with headache and blurred vision associated with halos around sources of light. The visual acuity was slightly reduced and the intraocular pressure in the left eye was elevated to 44 mmHg and in the right eye to 49 mmHg. Slit lamp examination of the anterior segment revealed bilateral cells and a Tyndall phenomenon 2 +, several cell clumps adherent to the corneal endothelium, known as mutton-fat keratic precipitates and a circumscribed inflammatory infiltration of the right iris. The posterior segment of both eyes was normal. The cause of the presumed clinical diagnosis secondary open angle glaucoma due to anterior granulomatous uveitis was sarcoidosis, confirmed by elevated serological markers of angiotensin-converting enzyme (ACE), soluble interleukin-2 receptor (sIL-2R) and by pulmonary hilar lymphadenopathy. The local and systemic corticosteroid therapy was successful and also normalized the intraocular pressure.
