How Concussion Can Impact Vision

Concussions are typically associated with sports injuries, vehicular accidents. As far as symptoms go, most people know that concussions can cause cognitive issues like loss of memory or even behavioral changes. But did you know that concussion can also impact vision? Learn more about the connection between concussion and vision.

What is a Concussion?

A concussion is physical trauma to the brain. It’s caused by a physical impact that causes the brain to unnaturally move within the head. It may come about from a fall, blow to the head, bump or sudden back and forth movement, such as what occurs during a vehicle accident. Inside, the physical trauma may damage brain cells or cause a chain reaction of chemical changes that affect the vision or other bodily processes. Note that concussion is a serious injury that always requires emergency eye services in Hummelstown, PA.

How Concussion Can Impact Vision

If you or someone you know has incurred a head injury with concussion, it’s essential that you seek medical attention right away. Concussion can lead to vision loss on a mild or serious basis. The worst concussions can even cause permanent blindness. The optic nerve is responsible for sending vision signals to the brain for interpretation. When the brain is damaged due to concussion, the signals received from the eyes through the optic nerve may be hindered or stopped.

What are Scleral Lenses?

Scleral lenses are an alternative form of contact lenses for people who are unable to wear traditional contact lenses for one reason or another. Your Hummelstown, PA eye doctor can help to determine if scleral lenses are an appropriate choice for your individual circumstances. Scleral lenses are different from regular contact lenses in the way they are shaped, their size, and the way they operate while in place on your eyes.

What are Scleral Lenses?

Scleral lenses are not contact lenses. Contact lenses rest atop the cornea, while scleral lenses vault over the top of the cornea. Hence, regular contact lenses make contact with the cornea; scleral lenses do not. The outer perimeter of scleral lenses rests gently on the whites of the eyes. In so doing, the scleral lens creates a perfectly smooth and rounded surface, which enables clear and focused vision.

Special Feature of Scleral Lenses

Since scleral lenses vault over the cornea of the eyes without making contact, it also creates a small cavity between the surface of the cornea and the inside top of the scleral lens. Fluid from the eyes builds up in this cavity to create a kind of reservoir. This is a special feature of scleral lenses that helps to treat the condition known as dry eyes. For this reason, scleral lenses are often recommended for dry eyes sufferers. Your eye doctor in Hummelstown, PA will let you know if you have dry eyes and if scleral lenses might work for you.

What Conditions Are Scleral Lenses Good For?

Besides dry eyes, there are other conditions that scleral lenses are particularly good for. Some people suffer with keratoconus. This is a condition where the shape of the eye is irregular and hard or impossible to fit with regular contact lenses. Scleral lenses are also commonly prescribed for those who have had a corneal transplant for any reason, Stevens-Johnson syndrome or complications with laser eye surgery.

Scleral lenses have been in use since the early 1900’s and they are a widely used alternative to regular contact lenses. Their practical use ranges from simple treatment for dry eyes to enabling people to wear lenses who otherwise would be unable to. Ask your eye doctor in Hummelstown, PA about scleral lenses to see if they are a good fit for you.

 

Are You at Risk for Macular Degeneration?

Getting to Know the Typical Risks of Macular Degeneration

Primarily, macular degeneration is considered an age-related condition. The breakdown of the optic nerve can be the result of the aging process for some individuals, especially those over 50 years old. However, there are a number of other risks associated with macular degeneration, including:

When to Talk to the Eye Doctor About Macular Degeneration

  • Distorted vision
  • Wavy lines in your vision
  • Blurry vision
  • Difficulty with recognizing common objects or faces

Testing and Diagnosis

A number of tests may be performed by your eye doctor in order to test you for macular degeneration. The initial test may involve dilating your pupils with special drops and then looking into the back of the eye for drusen, which can be more prevalent in the eyes of someone with macular degeneration. However, the eye doctor will likely perform a series of vision tests and tests using various instruments before making a proper diagnosis.
