| + | Glaucoma is rarely diagnosed due to lack of tonometers. Early stages often escape diagnosis due to the subtlety of the signs. It is commonly secondary to equine recurrent [[Uveitis - Donkey|uveitis]]. |
| + | |
| + | ==Clinical Signs and Diagnosis== |
| + | |
| + | A '''swollen globe''' should always be checked for increased intraocular pressure (IOP). Raised IOP is measured using a tonometer, following topical and [[Local Anaesthetics|local anaesthesia]] to reduce the pull of the extra ocular muscles. |
| + | |
| + | Signs are: |
| + | * Corneal oedema |
| + | * Blindness or visual defects |
| + | * Dilated, fixed pupil |
| + | |
| + | [[Lens Luxation - Donkey|'''Lens displacement''']] can cause secondary glaucoma; <u>mydriatics are contraindicated in this situation.</u> |
| + | |
| + | ==Treatment== |
| + | |
| + | Immediate action is required to reduce the IOP. Medical treatment is usually attempted first but response to treatment is variable. Consult an ophthalmology textbook for standard treatments or consult a specialist. |
| + | |
| + | * '''Miotics''' are indicated except for cases of [[Uveitis - Donkey|uveitis]] and [[Lens Luxation - Donkey|displaced lenses]] |
| + | * '''Surgery '''can be the best option |
