What is a common symptom of HSV keratitis?

A common symptom of HSV keratitis is the presence of corneal vesicles. Herpes simplex virus (HSV) keratitis typically presents with unilateral eye symptoms and can lead to serious complications if not treated promptly. The infection can cause the formation of vesicular lesions on the cornea, which can be identified through examination. These vesicles are a direct result of the viral replication within the corneal epithelium and manifest as small, fluid-filled blisters that can rupture, leading to ulceration and potentially scarring of the cornea.

Other symptoms often associated with HSV keratitis include photophobia (sensitivity to light), redness, and discomfort in the affected eye, but the key feature here is the presence of vesicles specifically related to the HSV infection in the corneal layer. Recognizing these vesicles during an eye examination is crucial for diagnosing and differentiating HSV keratitis from other ocular conditions.
