Central vision loss refers to the sudden or gradual loss of central vision. It involves the loss of detail in a person’s vision and instead seeing one or more dark, blurry spots in their field of vision. These spots may grow in size or multiply over time.

What is central vision loss?

In order to see, light must pass through the pupil, which is the small black dot in the center of our eyes. It is then translated into electrical signals by means of the retina, which is a layer of cells located at the back of the eye. The optic nerves transmit this information to the brain, which processes it.

The loss of central vision is often caused by a break in this process, usually due to damage to the macula located in the center of the retina. Central vision loss can be the result of injury or other health conditions.

Symptoms

The loss of central vision often begins with one small dark spot in one’s center of vision that swells over time. But it doesn’t always happen that way for everyone.

Other symptoms can include:

• The appearance of wavy or distorted vision
• One or more empty spots in the field of view
• Graying, dullness or bleaching in the perceived colors in vision
• Diagnosis
• Central vision loss is usually diagnosed by a healthcare professional who specializes in ophthalmology, such as an ophthalmologist or ophthalmologist. They will examine the person’s eyes to determine if there are problems with their central vision.

Some of these tests may include:

Light Inspection:

Highlight the patient’s eyes to check for biological abnormalities, such as dark spots, swelling, clots, or cataracts

Dilated pupils:

Dilated pupils for better insight into the eye or eyes

Amsler Network Test:

During this test, the patient is asked to look at the graph sheet with a point in the center, focusing on the point. They will first use one eye while covering the other with their hand or a piece of paper, and then move on to the other. If the grids on the graph sheet look wavy to the patient, or if they see more black dots than those in the center, they probably have loss of central vision.

Neurological examination:

Tests eye and brain

function Treatment Treatment for central vision loss can vary and often depends on the underlying cause.

Some of these conditions can include:

• Age-related wet macular degeneration (AMD) is a condition that causes macular deterioration due to the formation and pressure of new blood vessels. VEGF (vascular endothelial growth factor). This medicine prevents blood vessels from growing and slows vision loss
• Macular edema is a buildup of fluid around the macula, which can be treated by injecting steroids into the affected eye to reduce inflammation.
• Retinopathy is the growth and inflammation of the blood vessels around the retina, usually associated with diabetes. It can be treated by better
  controlling blood sugar levels Surgery may also be a treatment option. There are surgeries during which the natural lens is removed from the eye and replaced with an artificial telescopic lens.7 Some of these procedures are still in their experimental stages and are not yet widely available, while others are available for some time.
• For patients with conditions such as AMD, other treatment for central vision loss can include wearing special glasses, which can help the patient see better.
  In general, treatment depends on the cause of the central vision loss and may require multiple strategies.

Living with central vision loss

There are rehabilitation programs for central vision loss that teach patients coping strategies and coping techniques to live better with this condition.

A person’s diagnosis of central vision loss depends on their individual situation, including the health condition that causes vision loss.

Some people with central vision loss may experience a slight loss of their central vision that can be restored through certain medical interventions or surgeries. In some cases, central vision loss can correct itself over time.

However, this may not often be the case for many patients. Most patients will likely need some kind of medical intervention to either slow down, stop, or reverse central vision loss.

There is also the possibility that the patient will eventually suffer a significant or total loss of vision. But this will not be true in many cases.

Some people with central vision loss may be able to work and function or close to what their abilities were before they develop vision loss. Others will become more seriously ill and live with more restrictions. In these cases, patients may have to learn to adopt extensive adjustments in order to better cope with their situation.
Early
detection As with other health conditions, early detection and intervention are often key to improving diagnosis. Regular eye exams are important. If you have a personal or family history of eye disease, have diabetes or high blood pressure, have had an injury or trauma to your eye or eyes, or are older, you should ensure that you have an annual eye exam.

A word from Ibsar Specialized Center

If you suspect you have central vision loss, consult your health care provider or eye specialist. They may be able to offer treatments that can restore part or all of your central vision, or slow the rate of vision loss.

If central vision loss can’t be reversed or slowed, other treatment plans — including developing healthy coping strategies and making lifestyle adjustments — are available to help you better manage the condition.
