Canine anterior uveitis can be a debilitating, painful, vision-threatening disease. Several local and systemic diseases can cause anterior uveitis.

A thorough history and complete ocular and physical evaluations are necessary to ensure timely and accurate diagnosis. This article reviews the pathophysiology, most common causes, diagnostic recommendations, current therapeutic options, potential complications, and prognosis for canine anterior uveitis.
