Clinical features
Clinical features of a corneal ulcer (corneal infiltrate with an overlying epithelial defect) include:
- more discomfort than conjunctivitis
- red eye
- may be slight blurring of vision
- photophobia
- the ulcers may be difficult to see
- keratitis may be identified by a white/grey patch on the cornea - this represents a collection of white blood cells in the corneal tissue
- the use of fluorescein drops aid in diagnosis - lesions of the cornea stain green (fluorescein drops are orange and become more yellow after contact with the eye)
Notes:
- hypopyon is a leukocytic exudate, seen in the anterior chamber of the eye
