![]() If retinal detachment is identified, you may need surgery immediately to prevent or minimize permanent vision loss.Īs a retina specialist, Dr. 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. ![]() ![]() Many of these conditions can lead to a retinal tear or a retinal detachment, which is a very serious condition resulting in a partial or total loss of vision.According to Stefanie G. Serious diseases such as diabetic retinopathy or macular degeneration may also cause spots and floaters. These can occur spontaneously or result from injury to the head or eye. However, spots and floaters can also indicate serious retinal problems. Although distracting and annoying, these naturally formed spots and floaters rarely cause a loss of vision. We see these floaters as specs, bugs, strings, or webs depending on their shape. Then if a sudden collapse of the gel occurs, this can cause the vitreous to separate which causes microscopic particles to "float" within the eye, casting tiny shadows on the retina. As we age, the vitreous begins to become more liquid and loses its gel-like consistency. During childhood, the vitreous is like jello. Spots and floaters can also be caused by deterioration of the vitreous or retina as part of the natural aging process. These particles remain in the vitreous throughout life and are occasionally seen as spots or floaters. Often, small flecks of protein or other natural matter become trapped in the vitreous during the formation of the eye before birth. The center of the eye is filled with a clear, jelly-like fluid known as the vitreous humor. Therefore, if you experience new symptoms, you should call the office immediately and have your eyes examined to determine if this is a sight-threatening condition. Both flashes and floaters can be harmless symptoms of aging eyes, or they can be indicators of a serious eye disorder such as a torn retina. They can indicate vitreous detachment or a serious eye disorder. Flashes come and go in an instant and normally occur in only one eye at a time. They usually appear as if someone is shining a flashlight from the side of your eye. Flashes are bright points of light that literally flash into the field of vision when the eyelids are open or closed. When the spots appear rather fuzzy and seem to be strung together with a web-like thread, they are called floaters. Sometimes one can make them disappear by merely turning the head, moving the eyes, or blinking. Typically, they are seen in the same eye and in the same part of that eye. Almost everyone has experienced spots floating in his or her field of vision. They can be harmless or indicative of very serious eye problems. Flashes, Floaters, and Vitreous Detachment
