After a retinal tear has occurred the retina may begin to detach. Flashes and floaters are often the symptoms of a retinal tear. ![]() A sudden onset of flashing lights and multiple new floaters (little “cobwebs” or specks that float about in your field of vision) may occur. The initial symptoms of retinal detachment may be quite mild. It is a medical emergency and anyone experiencing symptoms of retinal detachment should seek assessment from an eye care professional immediately. Retinal detachment is a serious problem and can result in permanent visual loss. Retinal detachment can also develop from holes in the peripheral retina which develop in areas of retinal thinning. This fluid causes the retina to separate and detach from the outer layers of the eye. Retinal tears frequently lead to retinal detachment as fluid from the vitreous seeps underneath the retina. In some cases, the traction on the retina may create a tear. PVD’s are typically harmless and cause increased floaters in the eye. This separation of the vitreous from the retina is called a posterior vitreous detachment (PVD). It eventually collapses inwards, and separates from the retina. Over time, the vitreous gradually becomes thinner and more liquified. ![]() The vitreous is more lightly attached to the rest of the retina. The retina is attached to the wall of the eye only at the very front and at the back of the eye where the optic nerve goes to the brain. When we look at something, the retina acts like the film in a camera and captures the image. The retina is the very thin tissue that lines the inside of the eye cavity like wallpaper. The vitreous has a jello or egg-white consistency when we are young, and is firmly attached to the front of the eye on the inside (called the vitreous base). The inside of the eye is filled with a gel like substance called the vitreous. A more in-depth explanation of Retinal Detachments Surgery is successful in approximately 85% of cases, with repeat surgery leading to re-attachment of the retina in 95% of cases. Given enough time, all vision will be lost without surgery. Treatment includes removing the vitreous from the eye with a gas bubble and laser or placing a silicone band around the eye, with a gas bubble and a freezing probe. Retinal detachments develop as a result of traction on the retina by the vitreous that first creates a retinal hole, then with continued traction leads to a retinal detachment.
