What can I do about diabetes retina problems?

First, keep your blood glucose and blood pressure as close to normal as you can.

Your eye doctor may suggest laser treatment, which is when a light beam is aimed into the retina of the damaged eye. The beam closes off leaking blood vessels. It may stop blood and fluid from leaking into the vitreous. Laser treatment may slow the loss of sight.

If a lot of blood has leaked into your vitreous and your sight is poor, your eye doctor might suggest you have surgery called a vitrectomy (vih-TREK-tuh-mee). A vitrectomy removes blood and fluids from the vitreous of your eye. Then clean fluid is put back into the eye. The surgery often makes your eyesight better.
