Canine glaucoma old. These types of glaucoma are due to abnormalities in the structures of the eye which occurred during ocular development. One or both eyes may be affected. Primary glaucomas occur in the absence of other eye disease, and are therefore presumed to be genetic in origin. The most common type of glaucoma in dogs is primary angle-closure glaucoma (PACG). The least common type of glaucoma in dogs is primary open-angle glaucoma (POAG), although this is the most common type that affects humans. In the Beagle, POAG is an inherited autosomal recessive trait. Secondary glaucomas occur when other eye diseases alter
Canine glaucoma Canine glaucoma Canine glaucoma refers to a group of diseases in dogs that affect the optic nerve and involve a loss of retinal ganglion cells in a characteristic pattern. An intraocular pressure greater than is a significant risk factor for the development of glaucoma. Untreated glaucoma in dogs leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness. The group of multifactorial diseases which cause glaucoma in dogs can be divided roughly into three main categories: congenital, primary or secondary. In dogs, most forms of primary glaucoma are the result of a
