![]() If a PVD progresses gently, gradually, and uniformly, the symptoms are typically mild. Clear vitreous fluid fills the space between the condensed vitreous gel and the retina. Over the next 1 to 3 months, the vitreous gel further condenses and the sides of the gel also separate from the retina until the PVD is complete and the vitreous gel is attached to the retina only at the vitreous base (see Figure 1). Diagram of the vitreous cavity during posterior vitreous detachment. Eventually it cannot fill the whole volume of the eye’s vitreous cavity (which remains the same size during adulthood) and so the gel separates from the retina, located at the very back of the eye cavity.įigure 1. Over time, the vitreous gel that fills the eye becomes liquid and condenses (shrinks) due to age and normal wear and tear. They may appear like cobwebs, dust, or a swarm of insects-or in the shape of a circle or oval, called a Weiss ring. If PVD is complicated by vitreous hemorrhage, retinal detachment, epiretinal membrane, or macular hole, the flashes and floaters may be accompanied by decreased or distorted vision. Floaters are most bothersome when near the center of vision and less annoying when they settle to the side of the vision. ![]() Most patients experience floaters and flashes during the first few weeks of a PVD, but in some cases the symptoms are hardly noticeable. Symptoms in Detail Mild floaters in the vision are normal, but a sudden increase in floaters is often the first symptom of PVD.ĭuring PVD, floaters are often accompanied by flashes, which are most noticeable in dark surroundings. Most patients experience PVD after age 60, once in each eye, and the condition is usually non-sight-threatening but occasionally affects vision more permanently in the event of complication, such as retinal detachment or epiretinal membrane. These symptoms usually become less intense over several weeks. Flashes (streaks of light, usually at the side of the vision).Floaters (mobile blurry shadows that obscure the vision).Posterior Vitreous Detachment (PVD) is a natural change that occurs during adulthood, when the vitreous gel that fills the eye separates from the retina, the light-sensing nerve layer at the back of the eye.
