Canine glaucoma medically, although sometimes surgery is required. As the cause of primary glaucoma is often unknown, medical treatment is usually aimed at reducing the main sign of glaucoma (raised intraocular pressure) rather than at treating the cause of the disease. The aim of surgery in dogs with glaucoma is to reduce intraocular pressure. This is achieved by reducing aqueous humor production, or by improving drainage of aqueous humor from the eye. Laser surgery is often performed to selectively destroy the tissue, ciliary body, in an effort to reduce aqueous fluid production. Laser surgery can also be combined with placement of a
Henneke horse body condition scoring system before the race due to their high exercise levels, possibly also leading to a decrease in muscle mass. They explain the differences of results between the studies in part in that the participating horses of the 1990 Purina Race of Champions have had to qualify before and present a more highly-performing field of horses. Both Tevis Cup studies found that horses with a higher body condition score had, however, a significantly higher rate of not finishing the race due to lameness. Horses on pasture should enter the winter season at a body condition score of 6 or 7. On extremely
