Clinical Features

A corneal lesion from any cause results in :
- pain, photophobia and a red eye
- Vision may be reduced   

Examination
- Inspection using magnification may reveal corneal opacities, a corneal foreign body, Dendritic ulcer ; a corneal ulcer stained fluorescein ; corneal abrasion or erosion ; corneal abrasion stained ; corneal Scar (alkali) (click on titles to see examples)

-  Inspection after staining with fluorescein will demonstrate any epithelial defect.

Lesions include:
Herpetic Keratitis (Dendritic Ulcer): Herpes simplex infection results in a branching ulcer Dendritic ulcer

Therapy
– Oc Acyclovir

Complications - recurrence
- corneal scarring
- iritis and deep keratitis

NOTE:  Corticosteroids are contra indicated for they cause rapid progression and can lead to corneal perforation.


 Corneal Abrasion: A geographic area of epithelial loss.

Therapy
– occlusion with a firm pad results in rapid resolution

Corneal Foreign Body: Corneal FB Will be noted on inspection or following fluorescein stain

Therapy
– Amethocaine drop for anaesthesia and removal with a fine hypodermic needle
- Occlude until ulcer has healed

Viral Keratoconjunctivitis: Associated with the conjunctivitis may be a punctate keratitis with subepithelial infiltrates
