If a retinal tear is diagnosed, in some cases it can be repaired with an out-patient procedure like laser treatment or cryotherapy. Your doctor will look for retinal tears, retinal detachment, and any retinal thinning. To get a complete view of your retina, your eyes will be dilated. However, this can sometime take a few days. In the case of posterior vitreous detachment, if flashes occur, they usually subside immediately when the separation is complete and the vitreous tug is released. “That’s why it’s so important to see an ophthalmologist and have the symptoms evaluated,” said Dr. Without an exam, it is impossible to tell if flashes are a result of a clean separation or a retinal tear. ![]() Other signs include a sudden increase in floaters, a curtain in front of the eye, a loss of peripheral vision, or a narrowing of the visual field. A warning sign of a retinal tear is repeated flashes that could occur within seconds or hours of each other, said Dr. If left untreated, a retinal detachment may lead to permanent loss of vision. Fluid can enter through the tear and cause a retinal detachment. This tugging and friction can also result in a retinal tear. This is more likely to happen where the gel is more firmly attached, for instance, at the peripheral (side) retina.įlashes appear when the vitreous gel fails to separate cleanly and then tugs and creates friction on portions of the retina. If, however, the gel still adheres to the retina during this separation, problems can occur. As the gel changes consistency, it separates from the retina in a normal process called posterior vitreous detachment. Those changes may result from aging, extreme near sightedness, or a previous eye surgery. ![]() Schuman, MD, a retina specialist at Duke Eye Center, eye flashes and eye floaters are often caused by changes in the vitreous gel, the substance that gives the eye its shape.
