​​​​​​​What Causes Low Vision?

There are several diseases of the eye that can cause vision loss. Over time, the vision loss becomes so severe that low vision occurs. A few of these diseases include:

• Glaucoma: Glaucoma is a condition that increases the pressure in the eye, causing damage to the optic never. Without treatment, it can result in a loss of peripheral vision, and in time, tunnel vision.

• Macular degeneration: The macula is the part of the retina that allows you to see objects in your direct line of sight clearly. If the macula begins to thin, macular degeneration occurs. It can make objects in your direct line of sight blurry, and in time, it can cause dark spots in your central vision.

• Diabetes: If you don't have proper control of your diabetes, vision loss is one of the most serious and common complications.

• Retinitis pigmentosa: This disease causes a gradual loss of side vision as well as night vision. As the disease progresses, it can result in almost complete vision loss.

• Detached retina: A detached retina can occur during trauma to the eye. It can also happen due to a severe infection. The retina can be reattached surgically; however, even after reattachment, your vision may not be restored entirely, and low vision can occur.
  
  

Diagnosing Low Vision

Low vision can be diagnosed using a visual acuity test. If you cannot read the chart and your optometrist suspects low vision, further tests would be performed using magnifiers, lighting, and special eye charts. These are helpful in testing your depth perception and your visual field.

There is no cure for low vision. Once the vision loss has occurred, it cannot be reversed. There are low vision aids available to make daily tasks easier. While they won't correct your vision, they will improve your quality of life.
