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.

Cannulating tear duct
-
The nasal section of the nasolacrimal duct can be flushed thoroughly if the cannula can be threaded through the lacrimal foramen. In many cases of dacryocystitis the duct has dilated and burst so pus fills the ventral recess of the maxillary sinus. This requires general anaesthesia to flush the duct thoroughly

Corneal ulcer and keratitis caused by dacryocystitis
-
In cases of chronic dacryocystitis, pus is constantly in the conjunctival sac at the medial canthus and is in contact with the eye causing infection and ulceration. This rabbit is undeer anaesthetic and the picture was taken after all the pus was removed. The eyelids were glued together at presentation. These ulcers can be very painful

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

Exophthalmos
-
Bilateral exophthalmos is a feature of rabbits with impaired venous return to the heart. The eyes tend to bulge more if the rabbit is positioned with its head lower than the heart. Thymoma or thymic lymphoma is a common reason for this condition but it also happen in rabbits with congestive heart failure or other mediastinal masses such as abscesses.

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.
