Cherry Eye in Tibetan Spaniels
Cherry eye, or prolapse of the nictitans gland, can occur in Tibetan Spaniels. The third eyelid's tear gland pops out of position, creating a visible red mass. While startling to see, it is not painful and is surgically correctable. The gland should be repositioned, never removed, as it produces essential tear film.
Prevalence
Occasionally reported
Typical Onset
Under 2 years of age (most common in young dogs)
Severity
Moderate
Symptoms to Watch For
If your Tibetan Spaniel shows any of these signs, monitor closely and consult your veterinarian.
Risk Factors
- •genetic predisposition
- •weakness of connective tissue attachment
- •young age (connective tissue still developing)
- •possible hereditary component
Diagnosis
Visual diagnosis — the prolapsed nictitans gland is clearly visible as a red/pink mass in the medial canthus. No advanced imaging usually needed. Examination rules out other causes of eye swelling (tumors, foreign bodies, abscesses).
Treatment
Surgical replacement (tacking) of the gland is the recommended treatment — the Morgan pocket technique or anchoring suture technique repositions and secures the gland. NEVER remove the gland — it produces 30-50% of tear film, and removal leads to lifelong dry eye (KCS). Post-surgical recurrence rates are 5-20%. Medical management with anti-inflammatory drops is temporary.
Prevention
No proven prevention — the condition is caused by weakness of the connective tissue anchoring the gland. Choose breeders aware of cherry eye in their lines. Early surgical correction prevents secondary gland damage.
When to See a Vet
See your vet within a few days of noticing the red bulge. While not an emergency, prompt surgical correction is easier and more successful than delayed repair. Both eyes should be examined as bilateral involvement is common.
