Posterior Vitreous Detachment

Posterior vitreous detachment (PVD) is a common, age-related condition in which the vitreous gel that fills the eye naturally shrinks and separates from the retina. PVD is the most common reason patients are referred to a retina specialist. While PVD itself is usually harmless, the vitreous can tug on the retina as it separates, potentially causing a retinal tear or detachment. Symptoms include a sudden onset of floaters, flashes of light, and sometimes a cobweb or ring-shaped shadow in your vision. Most cases require only monitoring, but a thorough dilated exam is critical to rule out retinal tears. If a tear is found, prompt laser treatment can prevent retinal detachment.
