    Corneal involvement by herpes simplex virus is usually unilateral and typically presents with a red, tearing eye with foreign-body sensation. Epithelial dendrites, characteristic of this condition, are small arborizing epithelial lesions in the shape of a twig or branch. When a corneal dendrite is detected by staining with fluorescein, the patient should be immediately referred to an ophthalmologist.
