Corneal ulcer in a cat
What is a corneal ulcer?
The cornea is the transparent shiny membrane that makes up the front of the eyeball. A corneal ulcer is deep erosion into the third layer of the eye, giving it a cloudy appearance and is painful. The most common cause is trauma. This can result from eyelashes rubbing on the eye (entropion), cat scratch or contact with a sharp object. Most pets will rub the affected eye with a paw or on carpet to attempt to relieve the pain.
Diagnoses methods
Diagnosis is made by direct examination of the eye or in some cases using a special stain.
