What are meibomian gland tumours
These are tumours of the meibomian glands of the eyelids. These are common in older dogs and start as small bumps at the margin of the upper and lower eyelids. Many of these stay small (2 - 3mm) and do not continue to grow further, so there is never any rush to have them removed. Some of these tumours even rub or rest on the eye itself, but if they remain small, they do not appear to cause any irritation. Occasionally the tumours become “active”, and they start to become larger. Once evidence of enlargement is seen then they will only continue to grow until removed.
