Severe Manifestations of Diabetic Retinopathy
When diabetic retinopathy progresses, individuals may experience the presence of dark patches in their field of vision, as if they are suddenly unable to see clearly through that eye. Some individuals describe this phenomenon as an empty space or the sensation of something obstructing their vision. Failing to treat or allowing diabetic retinopathy to reach an advanced stage can lead to permanent vision loss. Unfortunately, in most cases, the loss of vision cannot be reversed.
Understanding Early Diabetic Retinopathy
Diabetic retinopathy is a condition that occurs in two stages: early and advanced. In the early stages, the growth of new blood vessels in the eye is hindered. This stage is known as nonproliferative diabetic retinopathy (NPDR). NPDR is characterized by the weakening of blood vessel walls within the retina, leading to the formation of small microaneurysms that leak blood into the retina. Over time, these microaneurysms can block blood vessels and impact vision. It is important to note that NPDR is a treatable condition.
