Figure 4: Cataracts in aging male rat
Case history and photos
Jerry was a SPF tested laboratory male rat, not used in experiments. He was adopted as an adult and neutered; living for 27 additional months with present owner. His date of birth was unknown, but his age was estimated to be over 3 years old at the time of death. Additional health history included a resolved pododermatitist, with treatment, following the development of hind limb weakness.
A white, cloudy, covering was noticed on the lens of both eyes. The cloudiness initially began with the left eye.
Jerry was maintained on a healthy diet, and living in a supportive caging environment for safety due to hind limb weakness. No treatment required specific to cataracts.
Jerry adapted well to the developing cataracts.
