What is the main complication associated with untreated diabetic retinopathy?

The main complication associated with untreated diabetic retinopathy is vision loss. Diabetic retinopathy is a condition that occurs when high blood sugar levels cause damage to the blood vessels in the retina, leading to changes that can impair vision. As the condition progresses, it can lead to more severe forms, such as proliferative diabetic retinopathy, where new blood vessels form in the retina that may bleed or cause scar tissue, resulting in a significant loss of vision.

Regular screenings and early intervention can help manage the condition and prevent its progression, but if left untreated, it will inevitably lead to irreversible vision impairment or complete blindness in severe cases. This highlights the importance of monitoring and controlling blood sugar levels in patients with diabetes to prevent diabetic retinopathy and its serious outcome of vision loss.
