What are some eye problems that are specific to certain horse breeds and why?
Some of the eye diseases in horses that are hereditary or suspected to be hereditary include:
- Multiple congenital ocular anomaly in the Rocky Mountain Horse, pony and miniature horse
- Lack of normal iris development (aniridia) in the Belgian, Thoroughbred and Quarter horse
- Congenital nuclear cataracts in the Morgan and Thoroughbred
- Congenital cataracts in the Belgian, Thoroughbred and Quarter horse
- Congenital Stationary Night Blindness (CSNB) in the Appaloosa, Paso Fino and miniature horse
- Optic nerve coloboma in the Quarter horse.
Other ocular diseases are diagnosed at a higher frequency in certain breeds and may be attributable to genetic defects that affect the body’s own response to the disease.
- Appaloosas and Warmbloods represent a large number of immune mediated uveitis or Equine Recurrent Uveitis (ERU) cases.
- Draft breeds, Haflingers in particular, and Paint horses appear to be predisposed to conjunctival squamous cell carcinoma (SCC).
