PATHOLOGY OF OCULAR LESIONS IN FREE-LIVING MOOSE (ALCES-ALCES) FROM SASKATCHEWAN

Clinical signs of impaired vision or neurological disease occurred in seven of 74 free-living moose (Alces alces) from Saskatchewan, Canada, submitted for necropsy between 1969 and 1994. Several lesions were fo und in each eye, including retinal degeneration (seven cases), catarac t (six cases), lymphocytic-plasmacytic anterior uveitis (six cases), c orneal scars (six cases), keratitis (four cases), and microphthalmia ( one case), but their cause was not determined. Moraxella bovis was iso lated from the cornea of one moose. Lesions in the brain and spinal co rd were mild or absent.
