Researchers at the University of California, Davis (UC Davis), School of Veterinary Medicine are seeking Appaloosa horses for participation in a clinical trial on equine recurrent uveitis (ERU).

Equine recurrent uveitis is an ocular condition that occurs when there is recurrent inflammation along the uveal tract in the eye and is a leading cause of blindness in horses.

“Appaloosa horses, known best for their white coat spotting patterns (termed leopard complex or LP), are eight times more likely than any other breed to develop this disease and four times more likely to go blind, suggesting genetics plays a major contributing role,” a clinical trial description from UC Davis read. “However, little is known about the specific genetic factors involved. The objective of this study is to determine the genetic factors contributing to ERU in Appaloosa horses.”
