Recurrent herpes of the eye is caused by reactivation of the virus in a latently infected sensory ganglion, transport of the virus down the nerve axon to sensory nerve endings, and subsequent infection of ocular surface. The following classification of herpes simplex keratitis is important for understanding this disease:
Herpes zoster ophthalmicus (HZO), also known as ophthalmic zoster, is shingles involving the eye or the surrounding area. Common signs include a rash of the forehead with swelling of the eyelid . There may also be eye pain and redness, inflammation of the conjunctiva , cornea or uvea , and sensitivity to light .
Acute retinal necrosis (ARN) [1] is a medical inflammatory condition of the eye. [2] The condition presents itself as a necrotizing retinitis. [3] The inflammation onset is due to certain herpes viruses, varicella zoster virus (VZV), herpes simplex virus (HSV-1 and HSV-2) and Epstein–Barr virus (EBV). [2] [3]
Keratitis is a condition in which the eye's cornea, the clear dome on the front surface of the eye, becomes inflamed. [1] The condition is often marked by moderate to intense pain and usually involves any of the following symptoms: pain, impaired eyesight, photophobia (light sensitivity), red eye and a 'gritty' sensation.

Progressive outer retinal necrosis (PORN) syndrome is a form of chorioretinitis, an infection in the retina, the back of the eye.The disease is most commonly caused by the varicella zoster virus and is found almost exclusively in patients with HIV/AIDS (acquired immunodeficiency syndrome).
Valganciclovir (Valcyte) is an antiviral drug that is also effective and is given orally: it is a pro-drug that gets converted into ganciclovir in the body, but is much better absorbed orally than the latter. The therapeutic effectiveness is frequently compromised by the emergence of drug-resistant virus isolates.
Since April, at least 65 people have tested positive for the virus — the first U.S. cases other than a single infection in 2022. Dairy cow herds in 16 states have been infected this year.
Herpes simplex, often known simply as herpes, is a viral infection caused by the herpes simplex virus. [5] Herpes infections are categorized by the area of the body that is infected. The two major types of herpes are oral herpes and genital herpes, though other forms also exist. Oral herpes involves the face or mouth.
