Overview of Canine Eye Trauma
Ocular trauma may result from either blunt or sharp forces applied directly to the dog’s eye. Blunt injuries to the eye are sustained when flat or dull objects strike the surface of the eye and often traumatize the eye without penetrating it. These concussive forces can result in forward displacement of the eye from the bony eye socket (proptosis), lens displacement (luxation), bleeding within the front chamber of the eye (hyphema), retinal detachment, fractures of the bones around the eye, and rupture and collapse of the eyeball (globe).
Sharp injuries occur when piercing, pointed or jagged objects connect forcefully with the eye. Common examples include cat claw injuries, thorns, branches and sticks, writing instruments, sharp toys, or small airborne objects. Potential injuries include laceration or abrasion of the eyelids, cornea, conjunctiva and sclera, penetration of the cornea or the eye itself, hyphema, lens displacement or lens capsule tear and orbital injuries.
Ocular trauma can affect dogs of any age. Younger dogs are more likely to act without caution around cats, and cat claw injuries are most likely to occur in puppies. Young dogs are also more likely to stray from their owners and become injured by other animals or be involved in road accidents. Working/hunting/outdoor dogs are more prone to ocular trauma because they run through wooded areas and under brush. They are also more likely to encounter other unrestrained or wild animals and vehicles. Non-neutered male dogs are more prone to roaming and are at a higher risk for traumatic injuries.
What to Watch For
Animals with minor ocular trauma may show the following symptoms:
Animals with major ocular trauma may show the following symptoms:
Diagnosis of Ocular Trauma in Dogs
Veterinary care includes diagnostic tests to determine the severity and extent of the injuries that were sustained by the eye and to determine appropriate treatments. There are several potential diagnostic tests. Recommendations depend upon the likelihood of the potential diagnosis. These tests may include:
Treatment of Ocular Trauma in Dogs
Treatment depends on the extent and severity of the ocular injuries. Treatment may involve either medical, or medical and surgical intervention to stabilize the ocular injuries.
Home Care for Dogs with Ocular Trauma
Obtaining immediate veterinary medical attention is critical as many forms of ocular trauma are vision threatening and most are associated with significant discomfort or pain.
Keep your dog quiet and confined to a safe area in order to minimize further injury. Do not allow him to rub excessively or traumatize the injured eyes. A protective collar called an Elizabethan collar may be necessary to ensure this and may be obtained from your veterinarian.
Do not administer human over-the-counter medicines such as Visine® or other ophthalmic products designed to reduce eye redness or irritation as the extent of the injury must be identified and appropriately treated.
Leash or directly supervise dogs when outdoors to avoid unforeseen encounters with other animals and traffic. It also helps to neuter male animals to reduce the incidence of roaming and straying away from home. In order to avoid claw injuries, keep new young dogs away from house cats during the initial stages of combined living, and ensure the cat is allowed a reliable means of escape from the dog.
