This is a very early stage of retinopathy that usually shows no apparent symptoms. Background retinopathy develops when the blood vessels within the retina grows tiny bulges known as microaneurysms, which leaks fluid, causing swelling and forming deposits known as exudates.

In rare cases, the part of the retina where central vision occurs (macula) may become swollen. As the result, vision maybe distorted.

Mild cases of background retinopathy are normally not treated.
