What is Low Vision?
Low vision refers to visual impairments that have a significant impact on your daily life and cannot be corrected using standard eyeglasses, contact lenses, medication, or surgery. Low vision can be caused by impairments such as:
Extremely Poor Eyesight
Extremely poor eyesight is defined as having a best-corrected visual acuity (BCVA) that is less than 20/70 in the eye with the clearest vision.
Significant Visual Field Loss
Significant visual field loss includes blind spots in your vision or a lack of peripheral vision, a condition more commonly known as tunnel vision.
The United States defines legal blindness as having corrected vision that is 20/200 or worse in the eye with the clearest vision. It is also defined as having a field of view that is constricted to 20 degrees or less.
What Causes Low Vision?
Low vision has many causes including eye disease, eye injuries, hereditary factors, and neurological diseases. Some conditions that may cause low vision include:
Glaucoma is a degenerative disease of the optic nerve, and can cause peripheral vision loss if left untreated.
Age-Related Macular Degeneration
Age-Related Macular Degeneration (AMD) is a disease that causes permanent central vision loss including blurry, or distorted central vision.
Cataracts are the normal aging change of the crystalline lens inside the eye and can impair vision, but in North America, they are usually treated with surgery. Cataracts are the most common cause of blindness worldwide.
Diabetic retinopathy is the result of diabetes and affects the blood vessels in your retina, distorting your vision as well as causing blind spots and blurry vision.
Retinitis pigmentosa is a rare genetic disorder that causes the photoreceptors in the retina to break down and die. Symptoms include poor night vision and peripheral vision loss.
Hereditary Factors and Eye Injuries
Some patients may have a genetic predisposition to low vision, especially if you have a family member with low vision. Eye injuries and some brain injuries can also result in low vision. Head injuries, brain damage, and strokes can reduce your visual acuity and visual field.
Low Vision Devices at OPMT Vision Centers
Though there is currently no cure for many of the diseases that cause low vision, devices are available to help patients cope and utilize the remaining vision they do have. At our Nashville location we are able to examine patients with low vision, help them understand the cause, and manage their visual impairments, using specialized devices to minimize the impact on daily life.
