Cherry eye: prolapse of the third eyelid gland
5-month-old English Bulldog with a smooth, rounded pink mass protruding from behind the leading edge of the third eyelid of the left eye for a week. There is slight mucoid discharge.
What is the recommended treatment?
chevron_right Show answer and explanation
A. Surgical replacement of the gland, for example with the conjunctival pocket (Morgan) technique
Correct. The third eyelid gland produces around a third or more of the aqueous tear fraction. Replacing it preserves its function; the conjunctival pocket or orbital anchoring are common techniques.
B. Excision of the prolapsed gland, which is the definitive solution
Excising it greatly increases the risk of keratoconjunctivitis sicca in the medium to long term, especially in breeds already predisposed to dry eye such as Bulldogs.
C. Complete removal of the third eyelid
As well as losing the gland, the mechanical protection of the third eyelid over the cornea is lost. It is only considered for tumours of that structure.
D. Topical corticosteroid for a month, as the gland always returns to its place
Anti-inflammatories may reduce the size slightly, but the gland rarely stays in place permanently; the longer it remains prolapsed, the more inflamed it becomes and the worse it responds to surgery.
lightbulb Key takeaway
Cherry eye: replace, never excise. It is common in Bulldogs, Cocker Spaniels, Beagles, Shih Tzus and mastiffs, often under 2 years of age and sometimes bilaterally. If it recurs, replacement is repeated with another technique.
