LOW VISION

What is low vision?

 

Low vision is the term used for a visual impairment.  Low vision is a loss of eyesight

that makes everyday tasks difficult.  A person with low vision may find it difficult to

accomplish activities such as reading, writing, shopping, watching television, and driving

a car.  Regular medical eye exams by an ophthalmologist (Eye doctor) are important to

diagnose visual impairments, treat those conditions that can be helped, and begin the

process of vision rehabilitation for individuals with low vision.  The doctor will complete

an eye exam asking questions about your medical history and any vision problems you

might be experiencing.  The exam will also include a number of tests designed to

evaluate your vision.  Your doctor may use a variety of instruments.

 

The most common types of low vision include loss of central vision, loss of peripheral

(side) vision, night blindness, blurred vision and hazy vision.

 

Common Vision Disorders:

 

Cataracts: Over 20 million people in the US alone have cataracts according to Prevent

Blindness America.  It appears as a clouding of the lens of the eye.

 

Glaucoma: Glaucoma is the second leading cause of blindness.  With glaucoma,

portions of vision are lost over time, usually with no warning signs or symptoms prior

to vision deterioration.  For many, a decrease in peripheral vision is the first sign of

glaucoma.

 

Age-Related Macular Degeneration (AMD): AMD is a leading cause of vision loss

among Americans over age 60.  It accounts for nearly half of all low vision cases.  There

are two types of AMD, wet and dry.  Wet AMD is known as advanced AMD and does

not have stages like dry AMD.  Dry AMD stages are early, intermediate and advanced.

 

Diabetic Retinopathy: According to the National Eye Institute, more than 30 percent of

Americans diagnosed with diabetes have some form of diabetic retinopathy.  It is a major

cause of blindness and is caused by damage to blood vessels in the back of the eye,

which is due to high blood sugar.

 

There are a variety of devices and tips to assist with managing low vision.
