Can shingles blind you?


Shingles (herpes zoster) is a viral infection that can affect the nerves and skin. It typically causes a painful rash on one side of the body or face, but in some cases, it can affect the eyes and potentially cause vision problems.

Shingles can affect different parts of the eye, including the cornea, iris, and retina. If shingles affects the cornea, it can cause a condition called keratitis, which can lead to scarring and vision loss. If the virus affects the iris, it can cause inflammation, pain, and sensitivity to light. Shingles can also affect the retina, which can lead to inflammation, blurry vision, or even permanent vision loss.

In rare cases, shingles can affect the optic nerve, which can cause inflammation and swelling, and potentially lead to vision loss. However, this is uncommon, and most people with shingles do not experience any vision problems.

If you have shingles and experience any changes in your vision or eye pain, it is important to seek medical attention immediately to prevent any potential complications. Early treatment can help manage the symptoms and minimize the risk of vision loss.
