What non-infectious condition can lead to canine uveitis?

Canine uveitis, which is inflammation of the uveal tract (the middle layer of the eye), can result from several non-infectious conditions. One important condition that can lead to uveitis is diabetes mellitus. In diabetic dogs, metabolic changes and the presence of diabetic complications can contribute to the development of uveitis. For instance, diabetes can lead to secondary complications like cataracts, which could provoke an inflammatory response and trigger uveitis.

Additionally, the structural and functional changes in the eye caused by diabetes, such as retinal changes or increased vascular permeability, may also play a role in the onset of uveitis. This relationship highlights the systemic effects of diabetes on various organ systems, including the eyes.

Other options mentioned, such as urinary obstruction, hyperbaric oxygen therapy, and gastroenteritis, do not have a direct or well-established correlation with the development of canine uveitis. While they may have various health implications, they are not typically associated with the specific inflammatory processes that characterize uveitis in dogs. Therefore, diabetes mellitus stands out as a significant non-infectious condition that can lead to this ocular inflammation.
