Rhegmatogenous retinal detachment in a hypertensive dog.

A 4-year-old dog of the Appenzeller strain with experimentally induced renal hypertension presented with apparently longstanding retinal changes, including hemorrhage, detachment, tears/holes, and anemia, in one eye and intravitreal hemorrhage in the other. The retinal tears/holes probably occurred following constant vitreous traction due to retinal hemorrhage and subsequent exsanguination of most of the retinal vasculature. This animal was reexamined six months later and most of these changes had persisted. Photodocumentation is presented.
