What is the most common ocular manifestation of HSV-1 infection?

The most common ocular manifestation of HSV-1 infection is keratitis. Herpes simplex keratitis occurs when the herpes virus infects the cornea, leading to inflammation and damage. This condition is particularly notable because it can recur, often resulting in scarring and potential vision loss if not treated appropriately. HSV-1 is known for causing epithelial keratitis, which is characterized by dendritic ulcers on the corneal surface, and can also lead to more serious forms such as disciform endotheliitis.

While conjunctivitis, uveitis, and retinitis can occur in herpes virus infections, they are not as prevalent specifically associated with HSV-1. Conjunctivitis is generally more linked to bacterial or other viral infections, uveitis typically involves more systemic issues, and retinitis is often seen with HSV-2 or other viral pathogens. Therefore, keratitis stands out as the primary ocular complication associated with HSV-1.
