Temporary Causes of Blindness and Blind Spots

When most people think of visiting an emergency eye doctor in Pittsburgh, PA, they think of things like traumatic wounds to the eye. However, a vision health emergency can actually be less obvious. This is the case when it comes to sudden changes in visual capabilities. From blind spots to temporary instances of blindness, any major vision changes should be treated as an emergency. Take a look at a few causes of temporary blindness and blind spots.

Migraine Headaches

Migraine headaches have the ability to cause changes in your vision. Many migraine sufferers report having light sensitivity, but some people can also experience temporary changes in visual capabilities. An ocular migraine, which affects the retina, can cause short-term vision loss.

High Blood Pressure

High blood pressure is one of the most common causes of temporary blindness. A spike in blood pressure affects the blood vessels that feed oxygenated blood to the retina and other parts of the eye. If this blood supply is disrupted, you may see spots in your vision or even temporary blindness in the most severe cases.

Acute Angle-Closure Glaucoma

When fluid in the eye is not capable of flowing as it should, it causes a buildup of pressure. This condition is what is medically referred to as acute angle-closure glaucoma. If the pressure within the eye is not treated immediately, you could be facing permanent vision loss. Signs of acute angle-closure glaucoma include blurred vision, halos around lights, and eye pain.

What Is Astigmatism?  

You may have heard the term “astigmatism” before, but if you’re like many people, you probably don’t know what astigmatism is. When you see your eye doctor in Pittsburgh, you can find out what astigmatism is and whether you have it. If you’re diagnosed, your eye doctor can also give you treatment. Here’s what you need to know about astigmatism.

What Is Astigmatism?

Astigmatism is a type of curvature of the eye that causes blurry vision no matter what the distance. This condition occurs when the front surface of the eye has a mismatched curve. The curved surface of the eye and the lens should be round like a ball, but instead, one or both of the curves is egg-shaped.

What Causes Astigmatism?

Astigmatism is a condition that is present at birth. Sometimes, astigmatism is so subtle that it goes undiagnosed.

What are the Signs of Astigmatism?

Symptoms of astigmatism include:

  • Blurry vision
  • Squinting
  • Vision distortions
  • Eyestrain
  • Headaches
  • Eye discomfort
  • Poor night vision

What Can Your Doctor Do About Astigmatism?

People who have astigmatism have many options for correcting their problems. Corrective lenses, either in the form of contact lenses or in the form of glasses, can help. Some people who have astigmatism also opt for surgical correction, which can help improve their vision.

If you have blurry vision and believe you may have astigmatism, start by getting an eye exam in Pittsburgh. Your eye doctor can diagnose your condition and make recommendations for treatment.
