How does diabetes influence the retina?

Diabetic retinopathy could also be a complication of diabetes, caused by high blood sugar levels damaging the rear of the eye (retina). It can cause blindness if left undiagnosed and untreated.

However, it always takes several years for diabetic retinopathy to achieve a stage where it could threaten your sight. Diabetes damages blood vessels everywhere within the body. The damage to your eyes starts when sugar blocks the tiny blood vessels that attend to your retina, causing them to leak fluid or bleed. to make up for these blocked blood vessels, your eyes then grow new blood vessels that don’t work well.

Over time, this disease can destroy the sharp vision during this part of the eye, leading to partial vision loss or blindness. Macular oedema usually develops in folks that have already got other signs of diabetic retinopathy. Retinopathy is bought on by prolonged levels of high blood sugar – the hallmark of diabetes – which damage the small blood vessels within the retina.

 This damage can cause animal tissue to form, which can pull the retina out of position. But if retinopathy is diagnosed early, blindness is usually prevented. Although many folks with diabetes develop impaired vision, fewer than 5% suffer severe vision loss. While high blood sugar can change the shape of the lens in your eye, low blood sugar doesn’t and this particular vision issue is usually corrected sooner by getting your blood sugar back to normal from a meal or snack.
