What is a corneal ulcer?
A corneal ulcer is a loss of tissue from the surface of the cornea. It can result from trauma, a foreign body, infection, or dry eye. Superficial ulcers typically heal with appropriate treatment, while deep ulcers require urgent and intensive care.
What are the signs?
- Squinting and frequent blinking
- Excessive tearing and discharge
- Redness and surface cloudiness
- Pawing or rubbing at the eye
- Marked sensitivity to light
Diagnosis
Fluorescein staining makes corneal damage visible, allowing the depth of the ulcer and its likely cause to be assessed. Tear tests and microbiological cultures are added when indicated.
Treatment
Superficial ulcers are treated with protective and antibiotic eye drops. Deep or progressive ulcers may require surgical intervention, such as a conjunctival flap. Ocular trauma always warrants urgent evaluation.
