As the damage to these blood vessels becomes more severe, people may start to experience symptoms such as floating spots, empty areas of vision, or blurred vision. Eventually, people may experience vision loss. Diabetic retinopathy is a leading cause of blindness.
In this article, we outline suitable foods to include and those to limit to help manage diabetic retinopathy. Additionally, we explain at causes, risk factors, and prevention strategies for diabetic retinopathy.

The condition occurs when long periods of high blood sugar lead to damage in the retina, which contains delicate blood vessels. Having too much sugar in the blood can block these blood vessels, causing them to leak fluid or bleed. To compensate, the eyes grow new blood vessels that do not work well and are prone to leaking and bleeding.
High blood sugar is a risk factor for the condition, and the ADA advises that keeping it within a person’s target level may delay or help prevent retinopathy.
The early stages of diabetic retinopathy may present with no symptoms. Because of this, it is advisable that a person attends annual eye exams. Avoiding or delaying appointments may be a risk factor for disease development.
However, in the later stages of the condition, a doctor may recommend the following treatments, especially if someone has changes to their vision:
- injections into the eye using medications such as anti-VEGF drugs or corticosteroids
- laser treatment to reduce swelling in the retina, make the blood vessels shrink, and stop leaking
- a vitrectomy, which is a type of eye surgery that doctors may recommend if the retina is bleeding or there are a lot of scars in the eye
