Even with good control, edema can occu. Years ago I lost weight, changed diet and I am currently pretty diligent with exercise but damage is done and the leaking continues so I get the injection regularly.

No, it's a complication of diabetes. High glucose levels damage the vessels in the eyes making them weak and prone to leaking into the retina which causes swelling, leading to blurred vision or vision loss. If the center of the macula isn't affected laser treatment can stabilize vision but any peripheral vision lost is permanent. Anti-VEGF injections is another treatment. It stops the leakage which causes the swelling. How much the vision improves or how much is lost varies which each individual. The number one reason for diabetic macular edema is poor glucose control over a long period of time. Uncontrolled diabetes damages the whole body.

I am not a diabetic. Is Diabetic macular edema a different type of diabetes?
