The typical symptoms of a retinal detachment include floaters, flashing lights, and a shadow or curtain in the peripheral (noncentral) vision that can be stationary (non-moving) or progress toward, and involve, the center of vision. Eventually, the leaking vitreous fluid gets behind the retina, separating the retina from other layers of the eye. When the retina is detached from the back wall of the eye, it is separated from its blood supply and no longer functions properly. Other symptoms of retinal detachment may include floating shapes in the field of vision or brief flashes of light.Īlthough there are several types of retinal detachment, the most common one starts when a tear or hole develops in the retina, and some of the gel-like substance that fills the inside of the eye (vitreous fluid) leaks through the opening. However, if the area of detachment is closer to the outer edges of the retina, then the visual loss may be more like a curtain being drawn over one side of the visual field (the "curtain effect"). ![]() For example, if the retina detaches near the macula, the part of the eye that is responsible for the center of the visual field (reading for instance), then there may be a sudden, significant blurring or loss of vision. Without this nourishment and support, the retina does not function properly, and this can cause a variety of visual symptoms. When the retina separates from the deeper layers of the eyeball that normally support and nourish it, the retina is said to be detached.

The macula is the part of the retina responsible for sharp, detailed vision.Ī.D.A.M., Inc. Central vision becomes severely affected if the macula becomes detached. When the retina becomes detached, bleeding from nearby blood vessels can cloud the inside of the eye so that you may not see clearly or at all. This type occurs in people who have uncontrolled diabetes, had retinal surgery before, or have long-term (chronic) inflammation. ![]() Another type of retinal detachment is called tractional detachment.A family history of retinal detachment also increases your risk. ![]() This is most often caused by a condition called posterior vitreous detachment. It can also be caused by trauma and very bad nearsightedness. This causes the retina to separate from the underlying tissues, much like a bubble under wallpaper. The most common type of retinal detachment is often due to a tear or hole in the retina.The vitreous - the clear liquid in the middle of the eye - is removed and replaced with gas or silicone oi. Light rays that enter the eye are focused by the cornea and lens into images that are formed on the retina. Vitrectomy is one treatment for a detached retina. The retina is the clear tissue that lines the inside of the back of the eye.
