There are many causes of weepy eye, so it's best to have it checked out by the vet. Malocclusion can sometimes be a cause as well as congenital deformities of the eyelid that cause irritation to the cornea (entropian). As mentioned in an earlier post, blocked tear ducts are another cause as well as bacterial or viral infections.
If the cause is viral or bacterial, it can be spread to other rabbits.
The condition can worsen, depending on the cause. Continual moisture from the eye can cause inflammation and hair loss around the eye.
