A consequence of diabetes, PDR involves the growth of new, abnormal blood vessels in the light-sensing retina. These blood vessels are prone to bleeding into the gel-like vitreous that fills the eye, causing vision loss. NEI is part of the National Institutes of Health. Researchers compared anti-vascular endothelial growth factor (VEGF) eye injections versus removal of blood via vitrectomy surgery and laser photocoagulation. Both treatments improved central vision for the majority of participants, although approximately one-third of the participants needed both anti-VEGF injections and surgery. The findings will help guide treatment for people with bleeding in the eye from PDR. The results were published in the
