What is the main symptom of herpes keratosis?

Herpes keratosis, also known as herpes simplex keratitis, primarily affects the cornea of the eye and is often associated with an infection of the herpes simplex virus. The main symptoms include blurred vision and photophobia (sensitivity to light), which are indicative of inflammation and irritation of the cornea. This condition can lead to significant discomfort and visual impairment due to the involvement of the eye's surface.

Blurred vision occurs when the cornea, which is responsible for focusing light onto the retina, becomes inflamed or damaged. Photophobia is a common symptom that arises because the inflamed cornea and surrounding tissues are more sensitive to light. Together, these symptoms signify a response to the viral infection and are critical for diagnosing herpes keratosis, allowing for timely treatment to prevent complications, including potential vision loss.
