Have AMD? Save your sight with an Amsler grid.Evaluation of the ophthalmologic patient.The retina cannot work when these layers are not attached. These cells line the inside of the eye and sends pictures to the brain. The retina is a layer of cells that are sensitive to light. Complex retinal detachment: Proliferative vitreoretinopathy and giant retinal tears. Care notes Ambulatory WHAT YOU SHOULD KNOW: Retinal (RET-i-nal) detachment occurs when the retina in the eye separates from the back of the eye.It slowly affects the retina and causes loss of night and side vision. Retinitis pigmentosa is an inherited degenerative disease. Many people will first have the dry form, which can progress to the wet form in one or both eyes.
Warning signs of a detached retina include increased floaters and light flashes. It occurs when the light-sensitive membrane separates from the back of the eye. Retinal detachment is a medical emergency. The repair works in about 90 to 95 of cases. There are two types - wet macular degeneration and dry macular degeneration. Retinal detachment surgery has a high success rate. This causes symptoms such as blurred central vision or a blind spot in the center of the visual field. In macular degeneration, the center of your retina begins to deteriorate. The hole may develop from abnormal traction between the retina and the vitreous, or it may follow an injury to the eye. A macular hole is a small defect in the center of the retina at the back of your eye (macula). This membrane pulls up on the retina, which distorts your vision. Epiretinal membrane is a delicate tissue-like scar or membrane that looks like crinkled cellophane lying on top of the retina. Or you may develop new, abnormal capillaries that break and bleed. This causes the retina to swell, which may blur or distort your vision. If you have diabetes, the tiny blood vessels (capillaries) in the back of your eye can deteriorate and leak fluid into and under the retina. Everyone notices the occasional floater, but a dramatic increase in the number or size of floaters. For instance, the sudden appearance of floaters, or objects that appear to drift through the visual field, can indicate that retinal detachment may occur. This usually occurs when fluid passes through a retinal tear, causing the retina to lift away from the underlying tissue layers. Retinal detachment is a painless condition, but it usually causes noticeable visual cues. A retinal detachment is defined by the presence of fluid under the retina. It's often accompanied by the sudden onset of symptoms such as floaters and flashing lights. A retinal tear occurs when the clear, gel-like substance in the center of your eye (vitreous) shrinks and tugs on the thin layer of tissue lining the back of your eye (retina) with enough traction to cause a break in the tissue. TypesĬommon retinal diseases and conditions include: Untreated, some retinal diseases can cause severe vision loss or blindness. Depending on your condition, treatment goals may be to stop or slow the disease and preserve, improve or restore your vision. Treatment is available for some retinal diseases.
