Final answer:
Diabetic retinopathy is the correct answer; it's caused by damage to the retinal blood vessels due to high glucose levels in the blood, often associated with diabetes.
Step-by-step explanation:
A leakage from the blood vessels of the retina into the body of the eye that can lead to permanently impaired vision is called diabetic retinopathy. Diabetic retinopathy is a condition that arises when high blood levels of glucose lead to damage to the blood vessels, particularly in the retina. Over time, this condition can lead to visual impairment and even blindness. It is one of the several long-term complications of diabetes, alongside other conditions like diabetic nephropathy (kidney damage) and diabetic neuropathy (nerve damage). The leakage from the blood vessels of the retina into the body of the eye that can lead to permanently impaired vision is called diabetic retinopathy. Diabetic retinopathy is a consequence of long-standing diabetes mellitus, where high blood glucose levels cause damage to the small blood vessels in the retina. Over time, this can result in vision loss and blindness.
