RESUMO
BACKGROUND AND OBJECTIVES: Anterior uveitis is the most common form of intraocular inflammation. The main aim of this study was to determine the viral etiology in patients with unilateral cases of anterior uveitis. PATIENTS AND METHODS: A total of 12 consecutive patients with the diagnosis of idiopathic unilateral anterior uveitis were included prospectively. Aqueous specimens were obtained from each patient by anterior chamber paracentesis and subjected to the detection of viral DNA/RNA genome by polymerase chain reaction assay for herpes simplex virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, and rubella virus. RESULTS: There were six male and six female patients. The mean age was 43 years, with an age range of 11-82 years. All 12 cases presented with unilateral anterior uveitis. In four (33%) patients, polymerase chain reaction was positive for viral genome. Two patients were positive for herpes simplex virus type 1, one patient was positive for cytomegalovirus and one for Epstein-Barr virus. CONCLUSION: Recent molecular diagnostic assays would help in the identification of the causative agent in patients with unilateral anterior uveitis.
