Lens Lesions in the Elk

Linsförändr ingar hos älg

Abstract

During the period 1973–1976, eyes from 17 elks (Alces a. alces L) were examined, bilateral cataract being found in nine elks, and a cataract found in an additional elk, from which only one eye was submitted for examination. Macro-scopically, the lenses were more or less deformed and reduced in size, being milky white or brownish grey and shrunk, their surface uneven and granular. Microscopically, there was a marked fluid accumulation between the lens fibers and apparently also a swelling of the lens fibers. Proliferation and swelling of epithelial cells were observed as well. Etiological factors are discussed.

Sammanfattning

Under tidsperioden 1973–1976 undersöktes ögon från 17 älgar (Alces a. alces L). Bilateral cataract påvisades hos 9 av dessa älgar. Hos ytterligare en älg, från vilken blott ena ögat erhällits för under- sökning, förelåg även cataract. Makroskopiskt befanns ögonlinserna mer eller mindre deformerade, förminskade och mjölkvita eher briin- grå samt skrumpna. Ytan var ojämn och granulerad. Mikroskopiskt sågs en päfallande vätskeansamling mellan linsfibrerna och uppen- barligen också en ansvällning av linsfibrerna. Vidare observerades an- svällning av epitelcellerna. Etiologiska faktorer diskuteras.
