Viral keratitis is an inflammation caused by the infection of cornea by virus. There are abundant trigeminal nerve endings in the superficial layer of cornea, so the disease often has obvious irritation symptoms, such as photophobia, tears, pain and so on. Symptoms of viral keratitis? Next, I'd like to share my views with you.
Symptoms of viral keratitis
According to the antigenicity and biological characteristics, herpes simplex virus can be divided into type I and type II. The corneal lesions caused by herpes simplex virus can invade all layers of the cornea and transform into each other. The most common typical forms are dendritic, map like, discoid, corneal uveitis and so on.
Keratitis caused by vaccinia vaccine infection is usually caused by vaccinia vaccine splashing into the eyes or being brought into the eyes by the fingers contaminated with acne pus. Generally after 3 days of incubation period, the onset, in addition to the performance of conjunctival and eyelid cowpox rash, about 30% of keratitis. Most of them were superficial keratitis and corneal ulcer, but less were stromal keratitis and discoid keratitis. Since the 1980s, smallpox has been eliminated all over the world, so vaccination against smallpox has been abandoned and the disease will disappear in the future.
Herpes zoster virus invades the ophthalmic branch of trigeminal nerve, causing superficial dendritic or stromal keratitis with severe neuralgia and beaded herpes on the skin. Herpes zoster virus and varicella virus belong to the same virus, so it is also called V-2 virus.
matters needing attention
Don't use eye drops indiscriminately. Many viral keratitis occurs because many patients don't have to check in time because of temporary discomfort in the eyes. Instead, they use eye drops at will to relieve symptoms and eventually cause viral cornea. Eye medicine should be used under the guidance of doctors, and the treatment should remember not to stop the medication as soon as the symptoms are relieved.
