Proliferative diabetic retinopathy is the advanced stage of diabetic retinopathy. “Proliferative” means that new blood vessels are growing — and these new vessels are the problem. They are fragile, abnormal, and tend to grow in the wrong places, including over the retina and into the vitreous (the gel-like fluid filling the eye).
When these fragile new vessels bleed, they can cause a sudden shower of floaters or a dramatic loss of vision. In severe cases, they can also cause scar tissue to form and pull the retina away from the back of the eye — a tractional retinal detachment.
PDR is serious but very treatable, especially when caught before bleeding or detachment occurs. Dr. Smithen will work with you to stabilize the condition and protect your vision.
- Sudden increase in floaters
- Dark streaks or a red haze in vision (from bleeding)
- Blurred vision that comes and goes
- Sudden vision loss
- Often no symptoms until bleeding occurs
Treatment for PDR
Anti-VEGF Injections
Block the signals that drive abnormal blood vessel growth, causing existing vessels to regress. Often the first-line treatment for PDR.
Pan-Retinal Laser (PRP)
Laser treatment applied to the peripheral retina to reduce the drive for new vessel growth. A proven, effective treatment for PDR.
Close Monitoring
Regular exams and imaging to track the response to treatment and catch any new bleeding or complications early.
PDR can be controlled. With the right treatment, new vessel growth can be stopped and vision preserved. The earlier treatment begins, the better the outcome. If you have had diabetes for many years, please do not delay your annual eye exam.
