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
Hypoxia (medical) Hypoxia (medical) Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either "generalized", affecting the whole body, or "local", affecting a region of the body. Although hypoxia is often a pathological condition, variations in arterial oxygen concentrations can be part of the normal physiology, for example, during hypoventilation training or strenuous physical exercise. Hypoxia differs from hypoxemia and anoxemia in that hypoxia refers to a state in which oxygen supply is insufficient, whereas hypoxemia and anoxemia refer specifically to states
