These new vessels are the body's attempt to overcome and replace the vessels which have been damaged by diabetes. But these new vessels are not normal. They may bleed, which causes vision to become hazy and sometimes causing a total loss of vision. These new vessels can also damage the retina by forming scar tissue and by pulling the retina away from its proper location. This stage, called proliferative retinopathy, requires immediate medical attention.
Treatment is necessary to prevent severe loss of vision.
Regular eye exams are crucial for all persons with diabetes. The progressing damage to the blood vessels in the eye can be slowed with treatment.
