Diabetic retinopathy can lead to poor vision and even blindness. Traction retinal detachment: scar tissue from neovascularization shrinks, causing the retina to wrinkle and pull from its normal position. More severe vision loss can occur if the macula or large areas of the retina are detached. In focal/grid macular laser surgery, a few to hundreds of small laser burns are made to leaking blood vessels in areas of enema near the canter of the macula. Doppler optical coherence tomography. This condition is called proliferative retinopathy. These conditions include diabetic retinopathy, diabetic macular enema DBE, cataract, and glaucoma. Laser surgery is often helpful in treating diabetic retinopathy. Proliferative diabetic retinopathy PDP.
It's caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye retina. A procedure called laser photo coagulation can be performed to seal or destroy growing or leaking blood vessels in the retina. These micro aneurysms may leak fluid into the retina. The dip in the retina is the fovea, a region of the macula where vision is normally at its sharpest. Nonproliferative retinopathy can move through three stages mild, moderate, and severe, as more and more blood vessels become blocked. DBE can be treated with several therapies that may be used alone or in combination.
