How Are Defects in the Visual Field Caused By Stroke Diagnosed?

Strokes are triggered by an abrupt interruption in the brain’s blood supply. Blockages in the brain’s arteries are the most common cause. A stroke can be caused by leaky blood arteries or bleeding in some situations. Damaged brain cells result from a disruption in the bloodstream, which cuts off oxygen delivery to areas of the brain.

If doctors suspect you had a stroke, you will be subjected to a series of medical and neurological tests. A physical examination, comprehensive blood work analysis, and a CT scan are likely to be included. In addition, an MRI and ultrasound may be used as further tests. This test will determine where your stroke occurred.

The following test would most likely be required to evaluate the extent of the influence on your vision:
● Measuring the sensitivity of central and peripheral vision is known as visual field testing.
● A computerized visual field analyzer is used to perform this exam in our office.

Visual Problems That Can Be Caused by Stroke

You may lose your ability to see clearly, your peripheral vision, and visual perception depending on where the stroke occurs in the brain. Your eye muscles’ mobility may also be hampered.

Vision problems that are caused by strokes such as homonymous hemianopsia and visual imperception might make it difficult to accomplish regular tasks like reading, watching TV, or driving. So it is possible that wearing glasses won’t help you see better.

What Is the Treatment for Visual Field Defects?

Unfortunately, medical treatments for vision loss caused by a stroke do not exist. Visual field loss caused by homonymous hemianopsia may improve on its own in some circumstances. As a result, after a stroke, the treatment focuses on learning to adjust for both visual field loss and visual imperception.

We urge that you engage with a low vision specialist if you have vision loss if you have vision loss resulting from a stroke. When dealing with hemianopsia-related visual field loss, the specialist will use equipment such as scanning techniques and prisms to assist you in compensating for the loss of vision on one side.

You may need to do eye exercises to improve the movement of your eye muscles. If you have trouble reading, especially if you have visual neglect, a low vision specialist can teach you ways to help you see the complete word or page.

The most important thing to remember is that getting medical help as soon as possible, including anti-clotting medicine, is critical to minimize the effects of a stroke. As a result, call your doctor or 911 as soon as you notice symptoms.
