Several studies have found a broad range of incidence of PVD, from 20% of autopsy cases to 57% in a more elderly population of patients (average age was 83.4 years). [4] People with myopia (nearsightedness) greater than 6 diopters are at higher risk of PVD at all ages. Posterior vitreous detachment does not directly threaten vision.
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
PVD: peripheral vascular disease: PVFS: post-viral fatigue syndrome: PVI: Peripheral vascular insufficiency Pulmonary vein isolation PVOD: Pulmonary venoocclusive disease: PVR: pulmonary vascular resistance Postvoid residual urine volume PVS: perivascular space persistent vegetative state pulmonary valve stenosis Plummer–Vinson syndrome: PVT
Sputter deposition is a physical vapor deposition (PVD) method of thin film deposition by the phenomenon of sputtering. This involves ejecting material from a "target" that is a source onto a "substrate" such as a silicon wafer. Resputtering is re-emission of the deposited material during the deposition process by ion or atom bombardment.
Peripheral vascular disease, or PVD usually involves the arteries, and so sometimes it’s also referred to as peripheral artery disease or PAD. PVD is most often caused by a blockage, called organic PVD, most commonly caused by atherosclerosis, which is a buildup of lipids and fibrous material just under the inner lining of the blood vessel ...
Additionally, the PVRI co-sponsors and supports a number of regional and worldwide events with the aim of advancing research and activities in the PVD field. Members of the PVRI have access to an online library of clinical management guidelines, educational materials, advice, and information about current research initiatives and clinical trials.

The ABPI test is a popular tool for the non-invasive assessment of Peripheral vascular disease (PVD). Studies have shown the sensitivity of ABPI is 90% with a corresponding 98% specificity for detecting hemodynamically significant (stenosis of more than 50%) in major leg arteries, defined by angiogram. [3] However, ABPI has known issues:
