![]() ![]() Among children, it affects 1% of rural Nepalese, 4% of South Africans, 12% of people in the US, and 37% in some large Chinese cities. Rates among adults are between 15% and 49%. Rates vary significantly in different areas of the world. Near-sightedness is the most common eye problem and is estimated to affect 1.5 billion people (22% of the world population). Surgeries like Implantable Collamer Lens (ICL) implant a lens inside the anterior chamber in front of the natural eye lens. Refractive surgeries like LASIK and PRK permanently change the shape of the cornea. Contact lenses can provide a relatively wider corrected field of vision, but are associated with an increased risk of infection. Eyeglasses are the simplest and safest method of correction. Near-sightedness can be corrected with eyeglasses, contact lenses, or by refractive surgery. This decrease in risk may be related to natural light exposure. Tentative evidence indicates that the risk of near-sightedness can be decreased by having young children spend more time outside. Myopia results from the length of the eyeball growing too long or less commonly the lens being too strong. Severe near-sightedness is associated with an increased risk of retinal detachment, cataracts, and glaucoma. Other symptoms may include headaches and eye strain. As a result, distant objects appear blurry while close objects appear normal. Near-sightedness, also known as myopia and short-sightedness, is an eye disease where light focuses in front of, instead of on, the retina. Near work, greater time spent indoors, family history Retinal detachment, cataracts, glaucoma Ĭombination of genetic and environmental factors If you notice a change in your vision or simply have not undergone a routine eye exam in a while, contact our office to schedule an appointment.Diagram showing changes in the eye with near-sightednessĭistant objects appear blurry, close objects appear normal, headaches, eye strain A sudden increase in the number of floaters, though, can indicate a more serious eye problem such as retinal detachment. Most people have some floaters and have no problem with their vision. Unlike scratches on the cornea, which follow your eye movements, floaters can drift even when the eyes are not moving. Some macular holes close up on their own while others require surgery to help improve vision.įloaters. These are specks, or “cobwebs,” that appear in the field of vision. Related to aging, this condition usually happens in people over the age of 60. Macular hole. This condition is caused by a small break in the macula, which leads to blurriness and distortion in the central vision. Sometimes, the scar tissue can fall off the retina on its own, and the vision will return to normal. The symptoms of a macular pucker are usually mild and do not require treatment. Although the symptoms are similar, macular pucker is not the same as age-related macular degeneration. Macular pucker. Scar tissue on the macula can make the central vision become blurry and distorted. The cancer starts in the cells of the retina, but can spread to other parts of the body (metastasize). Retinoblastoma. This cancer of the retina is generally uncommon although, it is the most common type of eye cancer in children. If not treated right away, a retinal detachment can lead to permanent blindness in that eye. ![]() It can cause symptoms such as floaters in the field of vision, light flashes and the feeling of a “curtain” in the way of your vision. Retinal detachment. This medical emergency happens when the retina pulls or lifts off of its normal position. Diabetics may also be at higher risk of developing other eye conditions, such as cataracts and glaucoma. This can lead to blurry or double vision, blank spots in the vision and pain in one or both eyes. One type of diabetic eye disease is diabetic retinopathy, which affects the blood vessels in the retina. Treatment can slow the loss of vision, but it will not restore vision that has already been lost.ĭiabetic eye disease. The high blood sugar (glucose) levels that occur with diabetes can also affect vision. This condition is a leading cause of vision loss in people over the age of 60 years old. This area is needed for the sharp, central vision that is used during everyday activities such as driving, reading or working with tools. Macular degeneration. Also known as age-related macular degeneration (AMD), this condition affects the center part of the retina, the macula. All retinal disorders affect your vision in some way, but some can also lead to blindness. This important part of the eye responds to light and passes on images to the brain. Retinal disorders are conditions that affect the layer of tissue at the back of the eye, known as the retina. ![]()
