There are two principal stages of diabetic retinopathy:

1. Non-Proliferative Diabetic Retinopathy:

It is an early stage of diabetic eye disease in which the walls of the blood vessels in your retina weaken, and tiny bulges (microaneurysms) start protruding from the vessel walls of the smaller vessels (in some cases) leading to the leakage of fluid and blood into the retina.

Larger retinal vessels also begin to dilate, and the vessels become irregular in diameter. It can progress from mild to severe as more blood vessel gets blocked. Nerve fibers in the retina are also affected as they may begin to swell. In some severe cases, the central part of the retina (macula) begins to swell (macular edema), a condition that requires immediate treatment from professionals.

2.  Proliferative Diabetic Retinopathy:

It is an advanced stage. The growth factors secreted by the retina are triggered, and the proliferation of new blood vessels begins, which grow along the inside surface of the retina and turn into the vitreous gel, the fluid that fills the eye. These new blood vessels are fragile. It makes them prone to leakage and bleeding. Sometimes scar tissue can contract and cause retinal detachment that is the pulling away of the retina from the underlying tissue. Retinal detachment leads to permanent vision loss.
