Progressive Stages of Proliferative Diabetic Retinopathy (PDR). (A) The proliferative stage of diabetic retinopathy is marked by neovascularization, visible on the optic nervehead (black arrow). Additionally, preretinal hemorrhage on the superior aspect of the nerve can also be seen (white arrow). (B) A subhyaloid hemorrhage (white arrows) manifests with boat-shaped configuration as it is trapped in the potential space between the posterior hyaloid and the internal limiting membrane. Preretinal hemorrhages can also be observed (black arrows). (C) Another complication occurring in this stage is the formation of a fibrovascular band along the superotemporal arcade, which can contract, causing tractional retinal detachment (white arrows).
