Blindness due to retinal disease
Due to the non-athletic nature of the donkey, early retinal disease is usually missed and it is not until significant damage has occurred that the loss of vision is noticed and the donkey is presented for examination.
Clinical Signs
Detailed ophthalmoscopic examination is required. Often the pupil is fully dilated already, as pupillary light responses are poor or absent.
During ophthalmological examination, look for:
- Pale optic nerve
- Depigmentation in the non-tapetum
- Blood vessel thinning
- Hyper-reflectivity of the tapetum
- Atrophy and decreased vascular supply to the optic disc
Differential diagnoses
- Retinal detachment, usually caused by inflammation or trauma
- Equine recurrent uveitis
- Chorioretinitis, discrete lesions in the nontapetal zone
- Optic nerve disease, unilateral or bilateral. Pupil is dilated with no pupillary light reflex (PLR). Untreatable.
Treatment
Retinal disease with visual deficits carries a guarded prognosis. The only treatment is the use of anti-inflammatories if an inflammatory aetiology is suspected. Tests for systemic disease are indicated in such cases.
Literature Search
Use these links to find recent scientific publications via CAB Abstracts (log in required unless accessing from a subscribing organisation).
