Hyphema associated with retinal disease in dogs: 17 cases (1986-1991)

Abstract

We evaluated the medical records of 17 dogs with hyphema of presumed retinal origin to evaluate the clinical, laboratory, ultrasonographic, and histologic features as well as known complications. The mean age of the dogs was 11.5 years. Routine hematologic and biochemical evaluation failed to identify an underlying cause in any dog. Retinal detachments, however, were identified in 10 of 13 dogs evaluated by ultrasonography and 5 of 6 globes evaluated histologically. In 1 dog, hyphema was associated with retinal vascular disease, presumed to be caused by hypertension. The prognosis for vision in geriatric dogs with hyphema, secondary to retinal disease, was found to be grave, as 10 dogs developed secondary glaucoma. The outcome for all dogs was loss of vision.
