AIM: While cytomegalovirus is well known as a pathogenic organism of retinitis, especially associated with human immunodeficiency virus infection, there are few reports of anterior uveitis associated with cytomegalovirus. METHODS: The authors present a case of keratouveitis associated with cytomegalovirus. RESULTS: A 70-year-old Japanese man was referred to the authors because of poorly controlled hypertensive keratouveitis in the left eye. The patient had a history of recurrent hypertensive anterior uveitis. At presentation, the corneal stroma was edematous, with Descemet's folds and pigmented keratic precipitates. The anterior chamber angle was depigmented compared to the fellow eye. Even though pupil dilation and posterior synechiae were absent, iris atrophy was not evident. His right eye appeared normal except for moderate cataract. Funduscopy of the left eye was hazy, with the optic disc showing a normal color but poorly defined details, and no apparent exdative retinitis. The best-corrected decimal visual acuity of the right and left eyes was 0.4 and 0.02, respectively. Intraocular pressure was 11 mmHg in the right eye and 35 mmHg in the left, despite maximum medical therapy. Systemic acyclovir and prednisolone for a month did not improve the hypertensive keratouveitis. The aqueous humor was investigated for herpes simplex virus, varicella-zoster virus and cytomegalovirus. Cytomegalovius genome was detected by polymerase chain reaction analysis. Oral valganciclovir rapidly reduced ocular hypertension within a week. CMV DNA disappeared 3 months after the initiation of valganciclovir. CONCLUSION: The authors reported a case of hypertensive keratouveitis with endotheliitis associated with cytomegalovirus.
