Image Octet Stream 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.

Image Episceral congestion
Episcleral congestion (engorgement of the blood vessels that run across the white part of the eye) is a feature of glaucoma. In rabbits, the blood engorged blood vessels to form a circle around the cornea. This syndrome is sometimes referred to as 'cilary flush'. The blood vessels become more prominent in eyes with a high intraocular pressure. This eye had an intraocular pressure of 28mm Hg measured by tonometry. Normal intraocular pressure is 15-23mm Hg

Image Octet Stream Glaucoma and staphyloma
This eye shows many abnormalities. There is corneal oedema, Descemet's streaks (Haab's striae), enlargement of the globe (buphthalmos) and an area of pigmentation at the limbus. There is mild episcleral congestion. The upper eyelid has a dysplastic section with an abnormal rim.

Image Arrows to abnormal areas of glaucomatous eye
This image shows the eye of a rabbit with glaucoma and staphyloma. The white arrow goes to the staphyloma that is an abnormal protrusion of the contents of the eye through a weak point in the eyeball. The protrusion is generally dark in colour, due to the colour of the inner structures of the eye. The red arrow goes to a congested episcleral blood vessel. The blue arrow goes to horizontal lines in the front of the eye. These are 'Haab's striae' . The red arrow goes to an extra flap or notch of abnormal eyelid (eyelid dysplasia) that can roll in and irritate the cornea.

Image Octet Stream Staphyloma
There is an area of pigmentation at the scleral junction that could be due to melanoma or staphyloma. A staphyloma is a protrusion of uveal tissue (contents of the eyeball). It is seen in association with glaucoma where globe enlargement stretches and thins the tissues. Scleral atrophy occurs at the limbus and allows uveal tissue to protrude.
