causes for ulcers in dogs eyes
Simple corneal ulcers can quickly become complex. If they do not heal within one or two weeks of aggressive medical treatment, there may be an underlying problem such as a weak attachment of the cornea to the basement membrane of the eye. Treatment will then need to progress as for deep, complex corneal ulcers. Complex corneal ulcers usually require all of the treatments described above for simple ulcers, followed by surgical intervention to save the eye. Depending upon the cause of the ulcers, topical treatments may be tried before surgery.
