title: [Glaucoma in dogs and cats. Review and retrospective evaluation of 421 patients. I. Pathobiological background, classification and breed predisposition].
abstract: Glaucoma is diagnosed frequently in dogs and cats. A review of case records at the University of Utrecht Small Animal Clinic revealed that during a 4-year period glaucoma accounted for 8.6% of all ophthalmological diagnoses. Glaucoma is defined as an increased intraocular pressure, which sooner or later leads to loss of function of the eye. Primary and secondary types can be distinguished. In primary glaucoma an increased intraocular pressure exists in the absence of other primary eye disorders. By gonioscopy a discrimination can be made between open and narrow or closed anterior chamber angle forms of primary glaucoma. This requires a clear distinction between the definitions of chamber angle and filtration angle. In the Netherlands primary glaucoma is seen especially in the American Cocker Spaniel, Bouvier and Basset breeds. In secondary glaucoma an increased intraocular pressure occurs as a consequence of another primary eye disorder. Dislocation of the lens is the main cause for secondary glaucoma. Several-mainly small-terrier breeds are predisposed to this entity.
