Introduction

In everyday clinical practice, among anterior uveitis cases induced by the herpes family of viruses, cytomegalovirus (CMV) anterior uveitis is relatively rare and is therefore often diagnosed with a substantial delay. Herpes anterior uveitis is a clinical diagnosis, and the three main causative agents, herpes simplex virus (HSV), varicella-zoster virus (VZV), and CMV, produce a similar clinical picture with subtle variations [1], [2]. The vast majority of herpetic uveitis seen by the practitioner is due to HSV or VZV when compared to CMV. This proportion is also reflected in studies performed on the identification of the viral agent in the aqueous humour, when we exclude Asian studies where CMV is more prevalent [3], [4]. In common practice, polymerase chain reaction (PCR) investigations are very rarely done, as the clinical picture of herpes anterior uveitis is quite characteristic, and the diagnosis is made relatively easily. In the presence of a unilateral, sometimes hypertensive, granulomatous uveitis with a moderate number of keratic precipitates (KPs) and possibly atrophy of iris sectors, the practitioner identifies a herpetic uveitis and applies the classical treatment of systemic valacyclovir or similar together with topical corticosteroid drops.
