This classic herpetic lesion consists of a linear branching corneal ulcer (dendritic ulcer).
During eye exam the defect is examined after staining with fluorescein dye.
The underlying cornea has minimal inflammation.

Patients with epithelial keratitis complain of foreign-body sensation, light sensitivity, redness and blurred vision.

Focal or diffuse reduction in corneal sensation develops following recurrent epithelial keratitis.

In immune deficient patients or with the use of corticosteroids the ulcer may become large and in these cases it is called geographic ulcer.
