How do you get shingles in your eye?

Shingles is a viral infection that affects the nerves and skin causing a painful rash. It is caused by the varicella-zoster virus, the same virus that causes chickenpox. Shingles can occur anywhere on the body, including the eye. However, shingles in the eye is relatively rare, occurring in about 10% of cases.

When shingles occurs in the eye, it is known as ophthalmic zoster or herpes zoster ophthalmicus. It can affect the cornea, the clear outer layer of the eye, the conjunctiva, the thin membrane that lines the eyelid and covers the white part of the eye, and the retina, the light-sensitive tissue at the back of the eye.

Ophthalmic zoster is usually characterized by the following symptoms:

- Painful rash around the eye

- Redness and swelling of the eyelid

- Sensitivity to light

- Blurred vision

- Tearing

- Headache

- Fatigue

In severe cases, ophthalmic zoster can lead to serious complications, such as:

- Corneal scarring, which can lead to permanent vision loss

- Glaucoma, a condition characterized by increased pressure in the eye

- Retinitis, inflammation of the retina

Treatment for ophthalmic zoster typically involves antiviral medications, pain relievers, and corticosteroids to reduce inflammation. In some cases, surgery may be necessary to treat complications such as corneal scarring.

If you have shingles and experience any eye symptoms, it is important to see an ophthalmologist (eye doctor) immediately for evaluation and treatment. Early diagnosis and treatment can help reduce the risk of serious complications.
