EYE PROBLEMS ARE ELUSIVE
Ocular problems in older horses often go unnoticed by owners, according to a new study from England.
Researchers at the University of Liverpool asked the owners of 327 horses age 15 years or older to fill out questionnaires about their horse’s management, medical history and clinical signs of disease. Only 3.3 percent of the owners reported that their horses had any eye disease. When veterinarians examined the horses, however, they found that 287 (87 percent) had cataracts, some vision loss or another eye-related abnormality.
In addition, the researchers found that a horse’s likelihood of developing eye abnormalities increased with age and those with no abnormalities were more likely to remain in active work.
