The following breeds are especially prone to hereditary causes: American Cocker Spaniel Boston Terrier Golden Retriever However, in advanced stages, once a dog is approximately 12 years old, the density can be great enough to cause nearsightedness or a myopic shift (difficulty seeing objects far away) and visual acuity reduction,31 as well as distort the practitioners examination of the retina.7 This change in vision is minimal enough that it does not warrant cataract surgery.

Systemic hypertension leads to ocular lesions in at least 62% of dogs.34 The retina and choroid are most commonly affected owing to the numerous small capillaries within the choroid susceptible to vascular ischemia, a condition known as hypertensive chorioretinopathy.34 The most common manifestation of canine hypertensive chorioretinopathy is retinal hemorrhage (ranging from petechiae to larger regions; FIGURE10), but other sequelae include serous retinal detachments, subretinal edema, and tortuous retinal vessels.34 Hyphema (blood in the anterior chamber), vitreal hemorrhages, and stromal hemorrhages are other, less common manifestations of ocular lesions secondary to systemic hypertension.28,34. 16.
