Herpes Simplex Uveitis

Findings

Discussion

When the eye is afflicted by herpes simplex, it usually affects only one eye and most often occurs on the cornea. The infection may be superficial, involving the epithelium of the cornea and usually healing without scarring, or it may involve the deeper layers of the cornea, leading to scarring of the cornea or loss of vision. Less commonly, herpes simplex virus may also infect the retina.
