In diabetes...abnormal blood vessels sometimes grow on the retina...these blood vessels do not nourish the eye, like normal blood vessels do...they are fragile...and can tear...as a result...they can then bleed onto the retina or into the vitreous cavity of the eye. The vision can be severely reduced. Treatment involves a variety of approaches...including laser, drug injections (such as Avastin) and vitrectomy surgery. Better control of blood sugar and blood pressure reduce the risk of such complications. Regular follow-up is also essential...if such blood vessels can be found before they bleed....laser treatment can usually cause the blood vessels to dry up and greatly reduce the risk of bleeding and blindness.
