Investigating the Structural and Functional Changes to the Retina Following PRP in Diabetic Retinopathy Patients

"Diabetic retinopathy does not usually impair sight until the development of long-term complications, including proliferative retinopathy, a condition in which abnormal new blood vessels may rupture and bleed inside the eye. When this advanced stage of retinopathy occurs, pan-retinal photocoagulation is usually recommended.~During this procedure, a special laser is used to make tiny burns that seal the retina and stop vessels from growing and leaking. Hundreds of tiny spots of laser are placed in the retina to reduce the risk of vitreous haemorrhage and retinal detachment."
