... or destruction of joints and bones. Additionally, in the diabetic population peripheral vascular disease (PVD) is the main risk factor for amputation. If PVD is not diagnosed, treatment of the ulcer cannot be successful. In diabetic patients PVD is distal, but often fully involves the femoral, popliteal...

... according to whether a posterior vitreous detachment (PVD) is present. In PVD-related detachments, the vitreous peels away from the retina potentially causing a retinal tear at sites of abnormal vitreoretinal adhesion, such as lattice degeneration ( fig. 1 ). Unfortunately, the vast majority of patients...
