Do all Appaloosas diagnosed with CSNB have the same degree of vision during the day? Is their day vision the same as or different from horses that don’t have CSNB?
CSNB-affected Appaloosas likely have normal day vision, just like any other horse. Day vision is only impaired if there is some other problem with their eyes (eg. cataracts). Some Appaloosas have “sky eyes”, where the eye tilts upward and backward from the normal position. These horses are thought to experience distorted vision. Unfortunately, there is no way to objectively test this, however, they frequently exhibit head-tilting and other unusual behaviors, and be unusually fearful of new places and objects which suggests visual abnormalities. The technical name for this disorder is “strabismus”, and it is considered a serious defect. However, many horses that exhibit this as young animals experience self-correction as they mature, such that by the time they are of riding age, their eyes move to a more normal alignment and their vision adjusts to near-normal.
