10 May Diagnosing Corneal Ulcers in Pets
The diagnosis of a corneal ulcer is made based on clinical signs and fluorescein staining of the cornea. After the fluorescein stain is put into the eye, the stain will be retained by the underlying stroma (or connective tissue) and appear green in colour. A corneal ulcer should be characterized regarding its size, depth, and the presence or absence of cellular infiltration. Any irritation or infection of the eye should be treated as an urgent matter and be seen by a veterinarian as soon as possible.
