Hypertension, Feline - contd.
The long-term prognosis for most cats with hypertension is unknown, and depends to some degree on the underlying cause. Blindness of short duration due to retinal detachment or hemorrhage may resolve, but most cats that have been blind for longer than one or two days will remain blind, even after their blood pressure has been controlled and the hemorrhage or detachment resolves. Very old cats with severe central nervous system abnormalities or severe heart disease do not have a good prognosis. If hypertension is diagnosed and treated before signs occur, serious complications may be prevented, but the effects of such treatment over many years have not yet been investigated.
