Cherry eye is a common term for prolapse of the third eyelid gland. Many Frenchies, have an “extra” or third eyelid located inside the lower eyelid. This serves as an additional protective layer for the eye. The third eyelid contains a gland that produces a significant portion of the tear film. When this gland prolapses or “pops out”, the condition is known as “cherry eye”.

What are the clinical signs of “cherry eye”?

Prolapse of the third eyelid gland appears a red swollen mass (named by its resemblance to a cherry) on the lower eyelid near the nose or muzzle. The “cherry eye” may be large and cover a significant portion of the cornea or it may be small and appear only periodically. Any sign of “cherry eye’ should be brought to your vet’s attention immediately.

What is the treatment of “cherry eye”?

Treatment involves medical therapy or surgical replacement of the third eyelid gland. It is important to treat the condition as soon as possible in order to minimize damage. This is critical because the third eyelid gland produces up to fifty percent of the watery (aqueous) portion of the tear film. Without adequate tear production, your dog is much more likely to develop “dry eye”, which can seriously impair vision. Your veterinarian will discuss the appropriate technique that will best suit your pet’s condition.
