Laser surgery – Depending on the condition of the eye, a variety of laser treatments can be used to shrink abnormal blood vessels and reduce fluid leakage inside the eye. While the goal of laser surgery is preventing further loss of vision, it does not cure diabetic retinopathy; and depending on the severity of diabetes, additional vision loss is possible.
Vitrectomy – With advanced cases, vitreous hemorrhage may occur. In this situation, the growth of abnormal blood vessels causes severe bleeding in the back portion of the eye. To treat this condition, microsurgery may be performed to remove the abnormal vitreous membranes and the blood in the eye.
