Pet's info: Small Animal | Guinea Pig | Female
My guinea pig has a small bump on the inner corner of her eye. It doesn’t seem to be bothering her, but I would like to know whether it is going to effect her or if it’s something serious.

This could be potentially rubbing against cornea and in the long term cause both chronic irritation/inflammation (the cornea can get darker than normal) and possibly corneal ulceration. This lump/growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infections or benign or malignant type of tumors.

This looks like a so-called cherry eye or a prolapsed lacrimal gland. In guinea pigs this is called pea eye. Contrary to cherry eye in dogs, this does not seem to be uncomfortable or painful in guinea pigs. If the protrusion interferes with vision, it can be removed with laser, however this is seldom necessary. In the case of your guinea pig, I would just observe the eye and, should it appear to get infected or grow, take it to the vet for an exam.

This looks like a lacrimal (tear producing) gland that has become inflamed or infected and and then prolapsed (popped up out of normal position). You can rinse the eye with tap water in a syringe (then drop it on the eye), and use a product such as this: but if its not improving over the next few days I would recommend that you have her evaluated by your veterinarian. thanks for asking PetCoach!
