Dogs can develop eye redness for a number of reasons, including allergies, an eye infection, or conjunctivitis. However, an eye that has a bulging red mass is usually something different – a condition known as the cherry eye or prolapse nictitans gland. Some cat and dog breeds are predisposed to this condition, and among them, Bulldogs are often affected. Read on to learn about the causes, symptoms, and treatments for cherry eye in Bulldogs.
Causes of Cherry Eye in Bulldogs: Issues with the Third Eyelid Gland
Have you ever noticed that your Bulldog’s eyes sometimes appear to be rolling back when they sleep? This is because dogs have a third eyelid – also known as the nictitating membrane – located in the lower eyelid's corner. When the upper and lower eyelids open during sleep and the third eyelid closes, this creates the appearance of a “rolling” or all-white eye.
The third eyelid contains a tear gland, which shouldn’t be visible in healthy dogs. In some dogs, however, the gland will bulge or pop out. When this happens, it is exposed to the air and loses moisture, which can cause irritation and a red, thickened appearance. This is what is referred to as cherry eye. Cherry eye is often caused by weak connective tissue that fails to hold the gland in place.
The cause of cherry eye is not completely known, but it is thought to be genetic and perhaps the result of weakened eyelid tissue. The eye and eyelid conformation in Bulldogs and other predisposed breeds can contribute to the development of cherry eye. While the condition often appears in Bulldogs, it is also common in Beagles, Boston Terriers, Cocker Spaniels, Bloodhounds, Bull Terriers, Saint Bernards, and Chinese Shar-Peis.
Symptoms of Cherry Eye in Bulldogs
Cherry eye can be seen as a bulging red lump protruding from the lower inner corner of your dog's eye (or eyes). While the prolapsed gland may look irritated, you may notice that your dog doesn’t seem bothered. This is because the third eyelid gland is not always painful. However, it can cause issues down the road if left untreated. The bulging gland prevents lubrication of the eye, which can lead to problems like an eye infection or dry eye, also known as keratoconjunctivitis sicca (KCS).
The third eyelid gland, also known as the eyelid gland, produces a significant portion of the tear film.
Treatment for Cherry Eye in Bulldogs: Options for Cherry Eye Surgery
Cherry eye surgery is almost always necessary to correct the cherry eye, and there are typically two surgical options: remove the affected gland or put it back in its normal position under the lower eyelid. Cherry eye is treated by repositioning the gland or, in severe cases, removing it.
The problem with removing the gland is that it is incredibly important for tear production, and without it, dry eye can easily develop. A dry eye is a permanent condition that can lead to blindness and usually requires lifelong medication. The third eyelid gland produces a significant portion of the tear film, essential for eye lubrication.
Saving the gland also has risks – for example, the cherry eye could come back, or the suturing used for the procedure could come loose and cause irritation. If this happens, it can sometimes be treated with medication, or a second surgery to remove the loosened suture may be necessary.
Most veterinarians now agree that the second option—preserving the gland—is the right choice. The gland is essential for tear production, especially as the dog ages and tear production decreases.
If the condition is caught early enough, some veterinarians may also suggest a holistic approach of eye drops and supplements to try to control the inflammation so that the gland’s normal position might be re-established.
If your Bulldog is showing signs of cherry eye, contact your veterinarian immediately. While the condition itself does not cause your dog pain, it can lead to serious problems if left untreated. Your veterinarian will decide which treatment option is best to treat cherry eye in your dog.
