Cytomegalovirus and herpes simplex virus as causes of bilateral anterior uveitis in an immunocompetent patient.

We report a case with two distinct clinical manifestations of bilateral anterior uveitis caused by two different members of the herpes virus group. A 72-year-old immunocompetent man, who had a documented history of two episodes of Posner-Schlossman syndrome in the left eye, presented with multiple mutton-fat keratic precipitates and elevated intraocular pressure (IOP) in his right eye. Herpes simplex virus Type I DNA was detected by polymerase chain reaction in the aqueous humor of the right eye. One year later, the patient appeared with a few round and whitish keratic precipitates and elevated IOP in his left eye. Polymerase chain reaction analysis showed positive for cytomegalovirus in the aqueous humor of the left eye. During both episodes, the anterior uveitis subsided and IOP returned to normal after systemic and topical antiglaucomatous medication as well as topical steroid.
