What Role Does Genetics Play in Low Vision?

Low vision is a term used to describe significant vision loss that cannot be fully corrected with standard glasses, contact lenses, medication, or surgery. While people with low vision still retain some sight, it can impact daily activities like reading, recognizing faces, or driving. Understanding the causes of low vision is essential for prevention, early detection, and proper management.

What Is Low Vision?

Low vision is not complete blindness, but rather a level of vision loss that interferes with everyday life. It may present as blurred vision, tunnel vision, blind spots, or reduced peripheral vision. It can affect people of all ages, although it is more common in older adults.

What Causes Low Vision?

There are several potential causes of low vision, including:

• Age-related macular degeneration (AMD)

• Glaucoma

• Diabetic retinopathy

• Retinitis pigmentosa

• Cataracts

• Eye injuries or congenital defects

While some causes are related to health conditions or environmental factors, others are rooted in genetics.

Inherited Eye Diseases That Cause Low Vision

Genetics can significantly influence your risk of developing certain eye conditions that lead to low vision. Inherited diseases such as Retinitis Pigmentosa, Stargardt Disease, and Leber Congenital Amaurosis are among the most common. Other inherited conditions include Juvenile Glaucoma, which increases eye pressure and damages the optic nerve in young individuals, and Achromatopsia, a disorder marked by complete color blindness and visual impairment. If you have a family history of any of these conditions, staying proactive with regular eye exams is essential for early detection and effective management.

The Importance of Regular Eye Exams

Since genetic conditions can develop gradually or begin early in life, routine eye exams are essential. Early detection allows for timely intervention that may slow progression or help manage symptoms more effectively. Comprehensive eye exams can also uncover underlying issues that may not present symptoms until vision loss has already occurred. We use advanced diagnostic technology to monitor your eye health and identify hereditary risk factors before they lead to significant vision impairment.
