Neovascularization: Hallmark of PDR

Preretinal hemorrhages: Appear as pockets of blood within the potential space between the retina and the posterior hyaloid face; as blood pools within this space, the hemorrhages may appear boat shaped

Hemorrhage into the vitreous: May appear as a diffuse haze or as clumps of blood clots within the gel

Fibrovascular tissue proliferation: Usually seen associated with the neovascular complex; may appear avascular when the vessels have already regressed

Traction retinal detachments: Usually appear tented up, immobile, and concave

Macular edema
