Ocular histopathologic observations in Norwegian Elkhounds with primary open-angle, closed-cleft glaucoma.
A retrospective histopathologic study of primary glaucoma in the Norwegian Elkhound was undertaken with the study of 9 clinically normal eyes and 22 glaucomatous eyes. All glaucomatous eyes showed goniodysgenesis as manifested by pectinate ligament dysplasia and/or trabecular meshwork dysplasia. Cystic degeneration of the iridociliary epithelial and/or peripheral retina was present in a high percentage of both normotensive and glaucomatous eyes. Utilizing the scheme proposed by Smith et al. (Veterinary and Comparative Ophthalmology 1993; 3: 16-28) the morphology of this disease in the Norwegian Elkhound would be classified as an open-angle, closed-cleft glaucoma, with histopathologic alterations of the outflow pathway similar to that described in other breeds with primary glaucoma.
