Symptom 7. Partial or Complete Vision Loss
In advanced stages of diabetic retinopathy, partial or complete vision loss may occur. This can be a sudden or gradual process, depending on the severity of the condition and the extent of the retinal damage.
Vision loss in diabetic retinopathy typically results from two main factors: macular edema and proliferative diabetic retinopathy. Macular edema occurs when fluid accumulates in the macula, leading to swelling and distorted vision. In more severe cases, this swelling can cause significant vision loss.
Proliferative diabetic retinopathy is characterized by the growth of abnormal blood vessels on the surface of the retina.
These new blood vessels are fragile and prone to leaking or bleeding, which can cause scarring on the retina and lead to vision loss. In some cases, the scar tissue can even cause the retina to detach from the back of the eye, resulting in severe vision loss or blindness.
If you experience sudden or gradual vision loss, it’s crucial to seek immediate medical attention. Early intervention can help prevent further damage and potentially restore some or all of your lost vision. (6)
