Cherry Eye (Prolapsed Nictitating Membrane Gland) in Neapolitan Mastiffs
Low Risk Category: Eye Typical onset: Under 2 years Hereditary: Yes Est. treatment cost: £600-£1,500
Cherry Eye (Prolapsed Nictitating Membrane Gland) is occasionally observed in the breed within the Neapolitan Mastiff. Common indicators include red or pink mass in inner eye corner, eye discharge, and excessive tearing. Cherry eye is the prolapse of the tear-producing gland of the third eyelid, appearing as a red or pink mass in the inner corner of the eye. It is more common in brachycephalic and young breeds, and can affect one or both eyes. It typically becomes apparent at Under 2 years. The giant frame of the Neapolitan Mastiff can accelerate progression in weight-bearing conditions, making early diagnosis particularly valuable. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £600-£1,500, making comprehensive pet insurance a practical consideration.
