Hereditary glaucoma
This condition was common among a line of purebred rabbits at a breeding establishment. The owners described it as 'blue eye'. It is also known as 'moon eye'. The condition is caused by congenital glaucoma. It is a hereditary problem that is passed down the generations. It can affect one or both eyes and eventually leads to blindness. Trauma to the surface of the eye can happen easily because the eyeball protrudes and is blind to objects that can damage it.
