Viral anterior segment eye diseases are common ophthalmic conditions and are of great importance because, in case of inadequate treatment, they can have significant repercussions on the quality of vision. As many infectious and non-infectious diseases of the anterior segment of the eye can be presented clinically in a similar way, with a quality clinical examination with a slit lamp and a comprehensive history, aqueous humor analysis and polymerase chain reaction (PCR) are of great benefit. This paper describes the conditions: conjunctivitis, keratitis, and anterior uveitis. Conjunctivitis is an inflammation of the conjunctiva, and when we talk about viral causes, by far the most significant cause is adenovirus. These are usually self-limiting diseases, however, in the case of complications and more severe forms of the disease, a timely reaction is important in order to preserve visual acuity. Sometimes excimer laser phototherapy keratectomy is the only therapeutic option to improve visual acuity. Viral keratitis is an inflammation of the cornea that is most commonly caused by the herpes simplex virus. The diagnosis of herpetic keratitis is made by clinical examination, and a rapid response and initiation of treatment are of utmost importance for the prevention of severe corneal damage. Anterior uveitis affects the anterior segment of the eye, most commonly the iris and ciliary body. The most common viral causes of this condition come from the family Herpesviridae, and the basic diagnostic method for determining the exact cause is the analysis of aqueous humor by PCR. In the treatment of anterior uveitis, the most important groups of drugs are acyclovir and its analogues, as well as anti-inflammatory drugs such as corticosteroids and non-steroidal anti-inflammatory drugs. The choice of the correct therapy in these cases will largely depend on the specific causative agent that led to the infection.
