Diabetic retinopathy- will it be cured?

[Ayushi]

Hello, my 52 years old male driver who had been diagnosed with type 2 diabetes mellitus (T2DM) five years ago without diabetic retinopathy at the baseline. He was being monitored for two intervals. It was at the second interval which he was diagnosed with proliferative retinopathy; in fact, the progression rate of retinopathy from its first sign, which occurred at the middle of the first and second interval, to the point at which he lost his vision from the left eye occurred within a year. Will it be cured? Please advise.

@ayushi Injecting medications into the eye. These medications, called vascular endothelial growth factor inhibitors, are injected into the vitreous of the eye. They help stop growth of new blood vessels and decrease fluid buildup. Two drugs are approved by the U.S. Food & Drug Administration (FDA) for treatment of diabetic macular edema — ranibizumab (Lucentis) and aflibercept (Eylea). A third drug, bevacizumab (Avastin), can be used off-label for the treatment of diabetic macular edema. These drugs are injected using topical anesthesia. The injections can cause mild discomfort, such as burning, tearing or pain, for 24 hours after the injection. Possible side effects include a buildup of pressure in the eye and infection. These injections will need to be repeated. In some cases, the medication is used with photocoagulation.
Photocoagulation. This laser treatment, also known as focal laser treatment, can stop or slow the leakage of blood and fluid in the eye. During the procedure, leaks from abnormal blood vessels are treated with laser burns.
Focal laser treatment is usually done in your doctor's office or eye clinic in a single session. If you had blurred vision from macular edema before surgery, the treatment might not return your vision to normal, but it's likely to reduce the chance of the macular edema worsening.
