Complications of Diabetic Retinopathy
When not treated immediately, new blood vessels that grow abnormally in the retina can cause serious vision impairment, even blindness. Some possible diabetic retinopathy complications include:
- Bleeding vitreus. This condition occurs when blood enters the middle of the eye, due to the rupture of newly formed blood vessels. If the leakage is low, the patient will only see floaters. But if the leaked blood is large enough, the patient’s vision will be completely blocked.
Although vitreous bleeding generally disappears in a matter of weeks or months, the patient is still at risk of permanent vision loss if the retina has been damaged.
- Retinal detachment. New blood vessels that arise due to diabetic retinopathy, can stimulate the formation of scar tissue in the retina. This scar tissue can pull the retina from its position, causing blurred vision, even triggering blindness.
- Glaucoma. When new blood vessels grow in the front of the eye, tear ducts can become blocked. This condition will trigger glaucoma (increased pressure inside the eyeball). Glaucoma can damage nerves and cause vision problems.
- Blindness. If not treated immediately, diabetic retinopathy, glaucoma, or a combination of both, can cause blindness.
