If it is cherry eye and not an allergic reaction, the best course of action is surgery. Here's a bit of a write up on it.
Symptoms of Cherry Eye in Dogs Introduction
“Cherry eye” is a condition where the gland of the ocular nictitating membrane (sometimes called a dog’s third eyelid, or a haw) essentially flips up and becomes enlarged and inflamed. The nictitating membrane is a thin sheet of tissue that in its normal position is seated deeply under the eye and is not visible. The prolapsed gland appears as a red mass bulging from the inside corner of the eye – looking somewhat like a small cherry. This condition can look terrible, but it is not an emergency and usually can be treated successfully with medication and surgery.
Symptoms of Cherry Eye
Often, a red mass bulging out from the corner of the dog’s eye is the only sign that an owner may see. They also may notice one or more of the following symptoms:
- Bright red mass protruding from the inner corner of the eye; sudden onset
- Red eyes
- Swelling around the eye
- Excessive tear production
- Eye dryness
- Abnormal discharge from the eyes
- Scratching and pawing at the eyes
- Vision impairment (bumping into furniture, etc)
Cherry eye can occur in both eyes at the same time (bilateral), or it can show up in just one (unilateral). It is seen most commonly in young dogs less than 2 years of age. The membrane normally does not slip out of place gradually. Instead, it tends to pop out of place suddenly, which can be alarming to owners. If cherry eye is not corrected, the dog can develop additional and sometimes rather serious ocular complications. The gland within the third eyelid produces a significant part of the fluid that makes up tear film. The primary function of the membrane itself is physical protection of the eye (particularly the cornea). When this membrane is not in the proper place, the eye can become red, dry, irritated and inflamed. There may be abnormal discharge from affected eyes as well. Some dogs seem annoyed by the misplaced third eyelid and will rub or scratch at it, possibly damaging the eyelid or maybe even injuring the cornea.
If you notice that your dog has what looks like a “cherry eye,” make an appointment with your veterinarian as soon as possible. This is not a life-threatening condition, but it should be treated promptly to prevent permanent damage to the eye.
