Ocular Herpes Zoster, also known as herpes zoster ophthalmicus or ophthalmic herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus (VZV) in the ophthalmic division of the trigeminal nerve. This condition primarily affects the eye and the skin surrounding it.
Herpes zoster is a viral infection that commonly causes shingles. When the virus becomes reactivated, it travels along nerve fibers, leading to the development of painful skin rashes, blisters, and fluid-filled lesions. Ocular herpes zoster specifically involves the eye region, which can lead to severe ocular complications if not promptly treated.
Typical symptoms of ocular herpes zoster include pain, redness, and swelling of the eye, blurred vision, sensitivity to light (photophobia), and in severe cases, loss of vision. The infection may also affect the cornea, leading to inflammation (keratitis), which can result in scarring or permanent vision impairment if not treated appropriately.
Treatment for ocular herpes zoster typically involves antiviral medications to control the replication of the virus and minimize the risk of complications. In addition, eye drops or ointments may be prescribed to relieve symptoms and prevent corneal damage. Corticosteroids may be used to reduce inflammation and speed up the healing process.
It is crucial to seek immediate medical attention if experiencing symptoms of ocular herpes zoster as prompt treatment can help prevent potential vision loss and alleviate discomfort associated with the condition.
