Herpes simplex dendritic keratitis

**Herpes simplex dendritic keratitis** is an infectious corneal disease of the ocular system, primarily caused by herpes simplex virus type 1 (HSV-1) and occasionally type 2 (HSV-2) It arises from active viral replication within the corneal epithelium, most frequently following reactivation of latent virus traveling anterogradely from the trigeminal ganglion to the ocular surface

It arises from active viral replication within the corneal epithelium, most frequently following reactivation of latent virus traveling anterogradely from the trigeminal ganglion to the ocular surface Patients commonly present with unilateral ocular pain, photophobia, foreign body sensation, redness, and reduced corneal sensation, which can progress to larger geographic ulcers or corneal scarring if left unchecked

Clinically, the hallmark finding is a characteristic branching, linear epithelial ulceration (dendrite) with terminal bulbs that stains vividly with fluorescein and rose bengal
