Corneal Trauma - Donkey
Jump to navigation
Jump to search
Introduction
Donkeys are less prone to trauma than horses due to their stoical nature and leisure uses, but their eyes are equally prominent and the cornea is usually involved.
Clinical Signs
The stages of damage progress from endothelial damage to anterior uveitis, lens luxation and retinal detachment.
Presenting signs are:
- Photophobia
- Blepharospasm
- Epiphora
- Corneal oedema
- Possible iris prolapse
Diagnosis
These signs are seen with many ocular diseases, so history and thorough examination is vital as treatment should be prompt.
Treatment
A ruptured globe requires surgical intervention and a lens luxation usually results in enucleation due to secondary glaucoma. Aggressive NSAID therapy and atropine are needed for the associated anterior uveitis.
