Dogs with hemangiosarcoma rarely show clinical signs until the tumor has become very large and has metastasized. Typically, clinical signs are due to hypovolemia after the tumor ruptures, causing extensive bleeding. Owners of the affected dogs often discover that the dog has hemangiosarcoma only after the dog collapses.
Radiation therapy has a multitude of accompanying side effects and should be recommended on a case-by-case basis. Dogs in which nose bleeds are observed have an average life expectancy of 88 days. In instances where nosebleeds are not seen, the prognosis is slightly less grim. On average, a dog with nasal cancer has a life expectancy of 95 days.
When the pterygium is removed, the tissue that covers the sclera known as the Tenons layer is also removed. Auto-grafting covers the bare sclera with conjunctival tissue that is surgically removed from an area of healthy conjunctiva. That "self-tissue" is then transplanted to the bare sclera and is attached using sutures or tissue adhesive.
A visibly white sclera is perceived as a sign of good health and youthfullness, [13] this could have been a criterion of selection when looking for a mate. In this case, humans' ability to communicate with their eyes (glancing, cluing at others) would only be a consequence of a very visible sclera.
