Cherry eye in dogs refers to the prolapse of the *nictitating membrane* (also called the third
eyelid), which appears as a bright red, swollen mass in the corner of the eye. It’s a common
condition, especially in certain breeds.
What is Cherry Eye?
– The nictitating membrane is a protective eyelid that helps keep the eye moist and protected.
– When the gland of the third eyelid prolapse or slips out of its normal position, it creates a
visible, swollen, cherry-like mass.
Breeds Predisposed
– Bulldogs, Cocker Spaniels, Beagles, Shihtzus, Lhasa Apsos, and other small or
brachycephalic breeds are more prone.
Signs and Symptoms
– Bright red, swollen mass in the inner corner of the eye (usually the right or left side).
– Discomfort or irritation—dogs may paw or rub at the eye.
– Excess tearing or discharge.
– Possible secondary conjunctivitis or irritation.
Causes
– The prolapse is generally idiopathic but may be associated with genetic predisposition or
trauma.
– No specific causes are usually identified, but it’s often seen early in life.
Diagnosis
– Visual examination by a veterinarian.
– Confirmed by inspection of the protruding gland.
Treatment Options
– Surgical correction** is the standard treatment.
– Most common procedure:
– Gland repositioning (tacking): Replacing the gland back into its normal position to preserve
tear production.
– *Gland removal is generally avoided because it can lead to dry eye (keratoconjunctivitis
sicca).
– Postoperative care includes topical antibiotics or anti-inflammatory medications.
Prognosis
– Good with surgical correction.
– Early intervention reduces risk of secondary dry eye or chronic irritation.
Important Note
– Do not attempt to adjust or remove the prolapsed gland yourself. Always seek veterinary care
for proper diagnosis and treatment.
