| − | 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
