Feline glaucoma is harder to recognise compared to canine glaucoma for both the owner and the vet. Whilst dogs usually presents with the ACUTE RED and BLUE eye cats usually present with slower, insidious, chronic signs. This article will discuss common clinical signs, causes and treatment plans for cats with glaucoma.

Clinical signs
1. Deep perilimbal hyperaemia - infrequent
2. Corneal oedema – variable in the acute stages more commonly seen in the later stages
3. Globe enlargement – commonly seen with inability to close the eyelids and central corneal ulcer due to exposure
4. Vascularisation of the cornea is variable
5. Blindness
6. Mydriasis - negative pupillary light reflex
7. Lens subluxation or luxation
8. Anterior uveitis
9. Elevated intraocular pressure (normal intraocular range is 10-25 mmHg in cats) - Ideal use a tonopen or tonovet
10. Retinal changes – very difficult to see changes in the retina and optic nerve compared to the dog
