The following article addresses various aspects of central vision loss with an overall look at the causes, signs, effects, and available interventions for people living with reduced central vision.
One of the more common forms of visual impairment affects central vision, which is responsible for detecting shapes and fine details.A loss or diminishment of central vision creates reliance on one's peripheral vision, which lacks the ability to discern detail, but is essential for mobility. As a result of this visual deficiency, everyday activities and daily living become difficult.
In the earliest onset of this form of visual impairment, the central part of people’s vision may appear blurry or appear to be missing details. This makes activities such as reading or using a computer or cell phone difficult or impossible without help. As the condition worsens, these deficits will appear as blank or blind spots. For example, this may manifest as an inability to see a friend’s face up close as a result of this impairment, while retaining the ability to see the rest of the person
There are various causes of central vision loss involving degenerative eye disorders, however, the primary cause is usually as a result of damage to the macula section of the retina, which is responsible for our ability to discern detail.
Additional factors affecting the macula that can cause central vision loss include the following conditions. A healthy macula is flat so distortions in shape or contour such as wrinkling, erosion, or swelling may cause central vision loss.
It is important to note that it is equally important to attend to these conditions before they degenerate and affect other aspects of vision and overall health. In the case of diabetic retinopathy and other diabetic conditions, attending to those conditions will benefit overall health.
As with many ocular conditions, the signs are not always apparent. Early detection is critical so that treatments and interventions can slow its progression. Always speak with an optometrist to determine how frequently you should schedule eye exams. Depending on your health and family history, you may require more routine exams. Possible signs of vision loss should be attended to right away. Contact our low vision optometrist if you have reason to believe that you are experiencing central vision loss.
Warning signs include:
A low vision optometrist is trained to assess ocular health for signs of central vision loss. A popular test low vision optometrists use to assess for central vision loss is the Amsler Grid exam where straight lines appear wavy to those with central vision loss.
Although low vision is irreversible, vision aids and rehabilitation can help maximize remaining vision and improve the overall quality of life. Central vision loss is often treated with optical and non-optical devices, prisms, medication, assistive technologies, and vision rehabilitation.
Early detection, diagnosis, and treatment are essential for preventing the condition that causes central vision loss from advancing. Ocular complications are difficult to detect so routine examinations are required to monitor overall eye health. Central vision is responsible for detecting shapes and fine details. As a result of this deficiency, daily living becomes difficult. People with central vision loss will have difficulty reading, using the computer or phone, and discerning faces. If you suspect that you or someone you know has central vision loss, contact our low vision optometrist to schedule an examination.
