Introduction

Posterior vitreous detachment (PVD) is a common age-related phenomenon characterized by dehiscence of the posterior vitreous cortex from the internal limiting membrane of the retina in conjunction with vitreous liquefaction.1 It often results in symptoms of flashes and/or floaters, and can be asymptomatic. Males and females are affected equally.2

The prevalence of PVD increases with age. While rare before the age of 50, it is present in over 60% of individuals over the age of 70.3 PVD mostly occurs without significant sequelae, but can result in a variety of retinal problems including retinal breaks, retinal detachment, and others.
