A variety of minor irritants can trigger a corneal abrasion in a dog: a run-in with the family cat, a scratch from a tree branch or bush while out on a hike, or even a bit of stray shampoo from a bath. Sometimes, despite treatment, a corneal abrasion will deteriorate to an ulcer or descemetocele. A corneal ulcer is a small hole in the cornea -- the clear, dome at the front of your dog's eyeball. Corneal ulcers are commonly caused by a trauma, such as your dog rubbing her eye on the carpet, from a cat scratch or contact with something sharp. If you notice any signs of a corneal ulcer or other changes in one or both of your dog's eyes, take her to a veterinarian for evaluation and treatment as soon as possible. Your veterinarian will examine the eyes to determine the extent of the damage to the cornea and check for signs of trauma or disease that may have caused the ulcer. If the ulcer is chronic or very deep, your veterinarian may take samples for culture before staining the eye. Treatment for a corneal ulcer depends on how long your dog has had the condition and the severity of the damage. Be careful not to touch the eye with the dropper, as it could damage the eye or bacteria from the eye could go into the ointment. If your dog paws or rubs her eye on the floor, she will need to wear an Elizabethan collar while the ulcer is healing. If your dog has a deeper ulcer, your veterinarian, along with prescribing antibiotics and atropine, may protect the eye while it heals, by suturing the eyelids closed or by covering the eye with part of the eyelid lining. On rare occasions, a really deep ulcer can lead to a ruptured eyeball or cause severe pain, which can't be controlled. When a deeper ulcer starts to heal, you may notice red lines covering the cornea and going to the ulcer.

Corneal abrasions are minor eye injuries, but seek treatment for them anyway -- they can develop into more serious eye injuries. The first reaction you may notice is that your dog is keeping his injured eye tightly closed. After the vet washes the dye away, he'll use an ultraviolet light to look for dye that remains. Antibiotic eye drops, administered every four to six hours, will minimize risk of infection. Administering medications as directed by your vet and making a followup visit within two or three days to check on his progress minimizes the chance that his injury will degrade. If your dog is being treated for a corneal ulcer, it's vital to attend all follow-up examinations with your veterinarian.
If you notice a discharge, the eye suddenly becomes more painful or doesn't look right in any way, go back to your veterinarian straightaway. Normally, there aren't any blood vessels in the cornea, but the body will form new vessels over the surface of the eye to speed healing. The cornea is transparent; the layers are visible only with the use of special stains that highlight specific cells for microscopic examination.
If your dog's corneal abrasion isn't healing properly, the vet may prescribe additional medication or recommend surgery. Some vets use a small strip of paper coated with dye, and gently touch the surface of the eye with the strip to apply the dye. Your veterinarian usually will prescribe an ophthalmic antibiotic ointment, applied every four to six hours, to prevent bacterial infection. He will remove any loose tissue and, with a fine needle, make small dot-like scratches to the exposed area so new skin cells can get a hold.

A dog can cope well with one eye, and quickly will get back to life as normal after her operation. If the blood vessels remain once the ulcer has healed, your vet may prescribe corticosteroid drugs or ointment to reduce them. A watery discharge may accumulate in the corner of the eye or may run down his face; if the injury becomes infected, the discharge may be colored. Your vet can perform a simple, and safe, fluorescein stain test to ensure the ulcer is healing. He also may prescribe atropine drops or ointment, applied twice a day, to relieve pain and spasms. If the eye becomes painful after using corticosteroids, immediately stop using them and go back to your veterinarian.
When the erosion extends beyond the epithelium and into the stroma, he has a corneal ulcer.
Once stained, large ulcers are clearly visible and small ones can be viewed under ophthalmic lights and filters.
If the erosion reaches into Descemet's membrane it becomes a descemetocele -- a serious condition.
