What is one outcome of untreated diabetic retinopathy?

Untreated diabetic retinopathy is characterized by damage to the blood vessels in the retina, which can lead to a range of complications for vision. As the condition advances without treatment, it often results in progressive vision loss.

This occurs because the damaged blood vessels may leak fluid or blood into the retina, causing swelling and scarring, which severely impacts visual function. Additionally, new abnormal blood vessels may form, leading to further complications and potential retinal detachment.

In contrast, improved overall eyesight, enhanced color vision, and increased depth perception are not outcomes associated with untreated diabetic retinopathy. These options suggest positive changes in vision, which do not align with the progressive nature of this condition and its effects on sight when left unmanaged. Thus, the correct outcome of untreated diabetic retinopathy is indeed progressive vision loss.
