This can lead to blood and other liquid leaking into the retina from the blood vessels. If left untreated, these blood vessels may bleed, clouding vision or scar detaching the retina. Small areas of balloon-like swelling in the retina’s tiny blood vessels, called micro aneurysms, occur at this earliest stage of the disease. Diabetic retinopathy happens when high blood sugar damages the tiny blood vessels of the retina. At some point, additional treatment may be recommended. By examining it, a doctor can inspect a sample of the body's blood vessels and detect early signs of complications of diabetes or high blood pressure, as well as many other diseases e.g., sickle cell disease, anaemia, lupus. Symptoms of a central retinal artery or branch occlusion include a sudden, painless loss of vision or decrease in visual field. When these blood vessels are damaged, they may leak blood and grow fragile new vessels. The outer eye is examined using an instrument called a slit lamp, and the inner eye is examined using an instrument called an ophthalmoscope.
