• Eight patients with proliferative diabetic retinopathy developed extensive retinal arteriolar
and capillary obstruction. Ophthalmoscopy showed many white, thread-like retinal arterioles
associated with capillary and venous dilatation. Widespread retinal arteriolar and capillary

in severe loss of visual acuity in some eyes. The severe degree of retinal ischemia was
accompanied by optic disc pallor and neovascularization and a high incidence of rubeosis …
