Which of the following is a symptom of diabetic retinopathy?

1. Blurred vision

2. Increased sensitivity to light

3. Narrowing of peripheral vision

4. Complete vision loss

The correct answer is: Blurred vision

Blurred vision is a common symptom of diabetic retinopathy, a condition that affects the blood vessels in the retina due to prolonged high blood sugar levels. As diabetes progresses, it can lead to damage in the retinal tissue, resulting in disturbances in vision. Blurred vision arises when the retinal blood vessels leak fluid or bleed, causing swelling in the area where visual signals are processed. This swelling disturbs the clarity of vision, leading to the perception of blurriness. Understanding the progression of diabetic retinopathy is essential, as early detection and treatment can prevent significant vision loss. If left unmanaged, diabetic retinopathy can worsen, leading to more severe symptoms and complications.
