Other Vision-Related Conditions


The following conditions, while not eye conditions, do affect vision and are therefore important to note.

Hemianopsia

Have you lost half your field of vision?

Hemianopsia affects either the right, left, upper, or lower side of the visual field, making it difficult—even dangerous—to perform everyday tasks like crossing the street. Hemianopsia can be caused by various medical conditions, but usually results from a stroke or brain injury. The condition is usually permanent and there is no specific treatment, but low vision rehabilitation specialists can help people learn to make the most of the sight that they have. In addition, some people with hemianopsia benefit from the use of magnifiers or special prism lenses.

Charles Bonnet Syndrome

Do you see images of patterns or objects or even people that you realize aren't there?

Charles Bonnet syndrome is not a mental disorder but a syndrome that can cause people to see a wide range of images—animals, buildings, shapes—that are not real. Such visual disturbances usually affect people who have experienced visual impairment or sight loss later in life. There are some treatments for Charles Bonnet syndrome, but sometimes the visual disturbances resolve on their own. People who have Charles Bonnet syndrome should consult with an eye care specialist.
