The cures for diabetic retinopathy include scatter laser treatment, vitrectomy and focal laser treatment, according to Mayo Clinic. The treatments are only necessary if diabetic retinopathy is at an advanced stage. Proper blood glucose regulation may slow the development of diabetic retinopathy if the condition is still in its early stages.
Scatter laser treatment, or panretinal photocoagulation, works by shrinking damaged retinal blood vessels with burns, explains Mayo Clinic. Though helpful, patients who undergo this treatment experience short-term blurred vision or inability to see at night. Vitrectomy involves first administering an anesthetic before removing blood that has leaked into the vitreous, which is the part that is located in the eye's middle, through an incision. It is also applicable in the removal of any scar tissue that pulls the retina repeatedly. Vitrectomy may not prevent retinal damage and eventual loss of sight because it only reduces the speed at which diabetic retinopathy develops.
Focal laser treatment, or photocoagulation, works by stopping blood from leaking into the eye due to an abnormality in the retinal blood vessels, using laser burns, states Mayo Clinic. Although patients who experience blurry vision due to swelling of the macula prior to focal laser treatment may not regain normal vision through this treatment, the procedure prevents further swelling of the macula.
Diabetic retinopathy is an eye complication that results from diabetes, notes Mayo Clinic. It occurs when the retinal blood vessels become damaged.
