Nictitating membrane gland prolapse

From Dog
Characteristic cherry appearance to the prolapsed nictitating mebrane in a dog[1]

Nictitating third eyelid membrane prolapse (cherry eye) is a common ophthalmology problem in dogs.

This disorder, which often occurs in young French Bulldog, Shar Pei, Great Dane, English Bulldog and Cane Corso breeds, can be readily managed with digital reinsertion of the gland within the third eyelid[2].

Some cases occur bilaterally, and may be associated with other conditions such as Horner's syndrome[3].

Clinical diagnosis is usually based on presenting clinical signs. Histopathology may be required if suspicion of an underlying neoplastic condition may be evident such as apocrine adenoma[4].

However, chronic prolapse of the gland often requires surgical intervention.

Surgery usually involves intranictitans tacking to anchor the prolapsed gland to the cartilage of the third eyelid[5] or the perilimbal pocket technique, suturing the subconjunctival tissues of the nictitating membrane to the episcleral tissues[6].

Surgical removal of the third eyelid is usually curative, but may risk development of temporary keratoconjunctivitis sicca in some dogs[7].
