What Is Laser Coagulation?
What are the treatments for diabetic retinopathy?
Laser coagulation
Right!
- Laser treatment can be used when proliferative retinopathy and macular edema occur.
- New blood vessels, fibroproliferation, and retinal detachment. Mostly in advanced patients, neovascularization is caused by acute hypoxia stimulation of large areas of tissue caused by retinal arteries. Neovascularization begins with the endothelial proliferation of blood vessels in the retina, extends through the inner limiting membrane to the inner surface of the retina, and grows in a potential gap between the vitreous and retina, accompanied by fibrous tissue proliferation. The fibrous vascular plexus or retinal vein can be torn with vitreous contraction, and sudden preretinal hemorrhage occurs. When the retinal hemorrhage and vitreous hemorrhage are large or recurring, they often cannot be fully absorbed and produce an organic film, which is attached to the retinal surface. Such organic compounds can cause retinal detachment and blindness.
