![]() Symptoms include a sudden or gradual increase in either the number of floaters, which are little “cobwebs” or specks that float about in your field of vision, and/or light flashes in the eye. Have other eye diseases or disorders, such as retinoschisis, uveitis, degenerative myopia, or lattice degeneration.Have a family history of retinal detachment.Have had a retinal detachment in the other eye. ![]() A retinal detachment is also more likely to occur in people who: ![]() It affects men more than women, and Whites more than African Americans. Causes and Risk FactorsĪ retinal detachment can occur at any age, but it is more common in people over age 40. In this type, fluid leaks into the area underneath the retina, but there are no tears or breaks in the retina. This type of detachment is less common.Įxudative - Frequently caused by retinal diseases, including inflammatory disorders and injury/trauma to the eye. Tractional - In this type of detachment, scar tissue on the retina’s surface contracts and causes the retina to separate from the RPE. These types of retinal detachments are the most common. Rhegmatogenous - A tear or break in the retina allows fluid to get under the retina and separate it from the retinal pigment epithelium (RPE), the pigmented cell layer that nourishes the retina. These areas, called retinal tears or retinal breaks, can lead to retinal detachment. In some cases there may be small areas of the retina that are torn. If not treated promptly, retinal detachment can cause permanent vision loss. When the retina detaches, it is lifted or pulled from its normal position. This can be corrected with laser surgery.The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. In some people, the surgery causes posterior capsule opacification, in which the part of the eye behind the artificial lens becomes cloudy. Before going ahead with surgery, it's important to weigh how bad your vision is against the small risk of surgery and the likelihood that it will improve your vision.Ĭataract surgery involves removing the clouded lens and replacing it with a plastic lens inserted in the eye during surgery.Ĭataract surgery improves the vision of most - but not all - people who have it. But the only way to cure a cataract is with surgery. ![]() People with cataracts can use eyeglasses, magnifying lenses, or stronger lighting to help improve their vision. Your eye doctor will likely widen (dilate) your pupils with medication and examine your eyes, and give you a visual acuity test to check your vision. Your story of your visual symptoms is an important part of diagnosing cataract. Symptoms of cataractĬataracts typically do not cause any symptoms until they have grown large enough to interfere with vision. In infants and young children, cataracts also can be one symptom of a disease that affects how the body processes carbohydrates, amino acids, calcium or copper.Ĭataracts are the world's leading cause of blindness, accounting for half of all cases of blindness. Some babies are born with cataracts, or develop them because of an infection that happened during pregnancy, such as toxoplasmosis, cytomegalovirus, syphilis, rubella, or herpes simplex. Some cataracts are caused by an injury to the eye, long-term diabetes, the use of corticosteroid medications, or radiation treatment. They first appear in the 40s or 50s, but may not affect vision until much later. It usually takes years for the clouding of the lens to keep light from reaching the retina or distorting light rays.Ĭataracts are usually an age-related condition. The name cataract comes from the term for "huge waterfall," which is how some people describe their clouded sight: like trying to look through a waterfall. This distorts or blocks the passage of light through the lens, causing cloudy or blurred vision, other visual problems, and even blindness. The eye's lens is a clear structure that focuses images on the light-sensitive retina.
