What is a post vitreous detachment (PVD)?

The vast majority of PVDs do not cause problems except annoying floaters and sometimes brief flashes of light. Improvement in symptoms is usually seen within a few months. Occasionally retinal tears can occur with PVD. Retinal tears can lead to a detached retina if the retina tear is not treated. There is no way to tell if a PVD caused a retinal tear so if someone has symptoms of a PVD they need a prompt dilated retinal exam.
