How Is A Canine Corneal Ulcer Treated
The treatment will differ depending on whether or not the canine patient has an eye abrasion, deep corneal ulcer, or descemetocele.
In most cases, the healing process for corneal abrasions takes between three and five days. A medication called ophthalmic antibiotics sprays or ointment is applied to the eye in order to prevent bacterial infections. This medication is also used to treat discomfort and spasms.
Antibiotic sprays/drops are only beneficial for a limited period of time. They need to be administered regularly antibiotic ointments last slightly longer but still need to be applied every few hours. Depending on the severity of the infection and how well your pet tolerates the medication, the antibiotic mixture should be given to your pet every 5 to 6 hours for the best possible outcomes.
On the other hand, the effects of atropine typically endure for several hours, which means that you only need to take this medication once every 16 to 36 hours.
What Happens During A Grid Keratotomy
Since a grid keratotomy is minimally invasive, general anesthesia is not required. In preparation for the procedure, your dog will be sedated and topical anesthesia will be applied using drops on the affected eye.
Once the patient is prepped, an eyelid speculum will be used to prevent the dogs eyelids from moving. Any loose epithelium tissue will be removed utilizing a cotton swab against the surface of the eye. Your dog will be restricted in order to prevent any movement and a needle will be used to prick the eye. Using a 20 gauge needle, multiple pricks and scratches are made through the stroma, or the thickest layer of the cornea. These pricks and scratches stimulate the epithelium, or the eyes outer layer, to heal by making it easier to reattach to the stroma.
Ophthalmic Examination And Diagnostic Testing
The ophthalmic examination revealed that the dog had moderate iris atrophy and nuclear sclerosis in both eyes. The left eye showed moderate conjunctival hyperemia, mild blepharospasm, and epiphora. A 5-mm-diameter area of fluorescein stain retention was identified on the dorsonasal quadrant of the left cornea . After gentle retraction of the third eyelid, a second 4-mm-x-2-mm area of fluorescein stain retention was located ventronasally . Both areas of ulceration were superficial and appeared to have loose epithelium at their edges. The results of Schirmer tear tests and tonometry were normal in both eyes, and the remainder of the physical examination was unremarkable.

What Are The Symptoms Of An Eye Ulcer In A Dog
A corneal ulcer is painful. If youve ever had grit in your eye, youll know just how sensitive the cornea is.
When the cornea is damaged, the eye becomes very painful, and this is how youll know something is wrong with your dog.
Signs of eye pain in dogs include:
- blinking more often than normal
- increased tear production
- altered behaviour
Dogs with eye pain may rub their face on the floor or other objects, or paw at it. They might react to people touching them around the face and they could seem grumpy. They may also try to avoid bright light.
Other signs your dog has an ulcer include the white of their eye looking sore and red, or the cornea appearing cloudy. You may even spot an indentation or hole in the surface of your dogs eye.
Causes Of Dog Corneal Ulcers
Accidents, dry eye, pathogenic infections, and entropion are among the most common causes of eye ulcers. These conditions lead to ulcers only when they are neglected for a long time and cannot be treated well in time.
Eye ulcers may be quite painful, and if they are not treated, they can rapidly become much worse.
How Will A Vet Treat An Eye Ulcer In A Dog And What Medication Will They Use
After diagnosing the ulcer and assessing for an underlying cause, a vet has many options, including:
- Antibiotics, which may be administered orally or via eye drops.
- Pain medication, such as atropine, or anti-inflammatories.
- Contact lens-style bandages to protect exposed nerve endings in the eye.
- Lubricating eyedrops.
- A buster collar to prevent the dog from pawing at its face or rubbing its face up against things.
Eye surgery is sometimes performed by a veterinary surgeon but may also be performed by a specialist known as a veterinary ophthalmologist.
The surgeon may perform a keratotomy, or debridement, which involves the removal of the ulcered epithelial cells. Then there is grid keratotomy, which involves making small incisions in a cross-hatched pattern across the ulcer and in healthy regions to promote healing.
In worst-case scenarios the dogs eye may be surgically removed. But dogs being dogs, they tend recover and adapt remarkably well.

What Does Surgery On A Corneal Ulcer Consist Of In A Canine
Most dogs diagnosed with corneal ulcers don’t require surgery. Their eye troubles are treated with medication. Dogs with deeper ulcers might require surgery for removal of dead tissue so the eye can heal. If your dog requires corneal surgery, ask your vet to recommend a board-certified veterinary ophthalmologist to perform the operation.
What Is Cherry Eye In Dogs
A cherry eye is a swollen 3rd eyelid gland. This gland lives under the bottom lid of your dogs eye, one the side near their nose.
When this gland gets inflamed, it will pop out from under the 3rd eyelid. Sometimes this will appear and, after a day or two, go away. Many times, this stays protruding from the eye.
What breeds are more common to develop a cherry eye? While any dog can get a cherry eye, it is more commonly seen in brachiocephalic dogs. Common breeds that get cherry eyes are:
- French bulldogs
Some of the most common signs of cherry eyes in dogs are:
- Swollen and red tissue in the corner of your dogs eye
- Discharge from your dogs eye
- Your dog is pawing at their eye
- Red and inflamed eye
If you notice any of these signs in your dog, it would be best for them to see your vet. Many eye issues need early treatment for the eye to heal properly.

Causes Of Corneal Ulcers In Dogs
The superficial layer of the cornea can be damaged as a result of the following:
- Chemical burns: From shampoo, skin medicine, ear cleaner, etc.
- Scratches: From accidental self-trauma, roughhousing or a fight
- Blunt trauma: From a car accident or running into an object, for example
- Penetrating injuries: From sticks, sharp toys, claws or teeth
- Rubbing: From foreign bodies under the eyelid, dry eye, lid problems or an itchy eye
Corneal ulcers in dogs can also develop when the corneal epithelium becomes diseased or infected. Minor injuries can lead to complications if they get infected. Primary infections of an otherwise healthy eye can also happen with some aggressive viruses and fungi.
Dogs can also develop a corneal ulcer for an unknown reason. In these cases, the condition is called indolent ulceration or spontaneous chronic corneal epithelial defects. This mostly occurs in dogs older than 6 years old.
What Is The Cornea
The cornea is the transparent, shiny membrane that makes up the front of the eyeball. Think of it as a clear windowpane. To understand a corneal ulcer, you must first know how the cornea is constructed.
There are three layers in the cornea, all of which are made up of highly specialized skin cells. The outermost layer is the epithelium, which is a very thin layer of cells. Below the epithelium is the stroma, which is the main supportive tissue of the cornea. The deepest layer is Descemet’s membrane. Because all of these layers of the cornea are clear, it is not possible to see them without special stains that color specific cells and highlight them when the tissue is examined under a microscope.
How Is A Corneal Ulcer Diagnosed
Superficial corneal abrasions are generally not visible without special tests and equipment. Corneal ulcers are detected with the use of special stains such as fluorescein. A drop of this stain is placed on the cornea. The dye will turn green and adhere to areas of ulceration. Large ulcers are readily visible, while tiny ulcers may be enhanced by the use of special ophthalmic lights and filters. A fluorescein stain test is the most common eye test performed and may be the only test needed if the ulcer is acute and very superficial. If the ulcer is chronic or is very deep, samples may be taken for culture and cell study prior to applying the stain or other medication.
Will Corneal Ulcer Heal Itself
A corneal ulcer is a medical emergency. Without treatment, it might spread to the rest of your eye, and you could lose some or all of your eyesight in a short time. You can also get a hole in your cornea, scarring, cataracts, or glaucoma. With treatment, most corneal ulcers get better in 2 or 3 weeks.

How Can I Help My Dog With An Eye Ulcer
The first thing you should do is get an Elizabethan collar for your dog. This will stop them pawing at or rubbing their eye, as this will prevent the healing from progressing.
Your veterinarian may also prescribe drops to be administered at home. This should be an easy task, simply applying one or two drops of the medication to each eye. Not all dogs will sit still for this, but it will help the ulcer to heal faster.
Ensure your home is dust-free to prevent dirt or bacteria from getting into your dogs eye. An infection can worsen your dogs eye condition and will mean a considerably longer healing process.
To prevent your dog from getting ulcers again in the future, there are a few things you can do. Firstly, keep your lawn trimmed short as running through long grass can cause damage to the eye and lead to an ulcer.
If your dog is a working dog and therefore cannot avoid heavy vegetation, you should invest in a pair of dog goggles to protect their eyes.
Stick to the prescribed medication, even if the eye starts to look better. Chances are the ulcer is still present, just less visible. The full course of treatment must be administered and your vet will likely request a follow-up consultation.
What Is Chronic Ulcer Surgery
Chronic ulcer surgery is a surgical procedure used to treat indolent ulcers in dogs. Although this surgical procedure can be performed by a veterinary surgeon, dog owners are often referred to a veterinary eye specialist to carry out the treatment. Chronic ulcer surgery, known as keratotomy in the veterinarian world, involves the removal of epithelial cells that no longer are attached to the stroma, or ulceration. This procedure can be carried out under general or topical anesthesia, depending on the size of the ulcer.

Most Frequent Dog Corneal Ulcer Diagnosing Stain
The fluorescein stain test is the most frequent type of canine eye test, and if the pups ulcer is severe and extremely shallow, it may be the only necessary test. Before administering the stain or any other medicine, samples can be obtained for culture and cell analysis if the ulcer is persistent or deep. This would come before any treatment with the stain or any other drug.
How To Treat Dog Eye Ulcers
Treatment of dog eye ulcers depends on 3 things:
- Whether the ulcer is deep or superficial
- Whether the ulcer is complicated or uncomplicated
- How rapidly the ulcer is growing
Superficial, uncomplicated dog eye ulcers can usually be treated with antibiotic eye drops or ointment that are applied several times a day. Pain medication is also prescribed, and dogs are fitted with an elizabethan collar to prevent them from scratching their eye while it is healing. Some eye medications can cause drooling. With treatment, superficial uncomplicated dog eye ulcers heal in 5-7 days, at which point you will take your dog back for a repeat eye stain test to see if the ulcer has healed. Cost of treatment is generally between $25-$50.
If an ulcer doesnt heal after one week of treatment, then it is considered complicated, and the underlying cause must be resolved in order to resolve the ulcer. If the underlying cause is an eyelash or eyelid abnormality, surgery is usually required to correct it. If the underlying cause is dry eye, then medication will be prescribed to improve tear production and lubricate the eye. If the pet has a thickened, chronic ulcer that wont heal, then surgery on the ulcer itself may be required. If the ulcer is deep and rapidly spreading, your dog may need to be hospitalized for surgery immediately to save the eye. Cost of treatment of complicated ulcers depends on the underlying cause. Surgery can cost several hundred dollars to $1,000 or more.

How Veterinarians Diagnose Eye Ulcer In Dogs
Your veterinarian will want to perform some eye tests to find the cause of the ulceration and to decide on a course of action for treatment. The most important part of diagnosing and treating eye ulcers in dogs is to figure out if the erosion is simple or complicated.
A simple eye ulcer only involves the most superficial layer of the cornea and usually heals within 7-10 days without progression into the deeper corneal layers.
A complicated eye ulcer extends into the deeper layers of the cornea and can become infected or even start melting the deeper layers because of severe inflammation and microorganism invasion.
There are three types of complicated ulcers:
Persistent corneal ulcers: This includes superficial ulcers with an elevated outer rim making it more difficult for the cornea to heal itself. They often heal with longer courses of therapy over several weeks to months. They sometimes require surgery to correct the problem if they worsen or do not heal with the right therapy.
Corneal foreign bodies: Objects can penetrate superficially or can penetrate the deeper layers of the cornea. The deeper the foreign body goes the faster and more intense inflammation occurs. Often these foreign bodies require careful removal by a veterinarian and aggressive therapy to heal. Surgery is sometimes necessary.
Diagnostic testing that is usually performed by your veterinarian may include:
