New Eye Technology Can Help Diagnose Brain Injuries
Eye movements are very important, take a look at this article from CBS Minnesota which talks about how a new eye technology can help diagnose brain injuries.
Brain injuries are the No. 1 cause of death and disability in Americans under age 35, according to the U.S. Centers for Disease Control and Prevention. Now, a new technology that looks at your eyes can help doctors diagnose brain injuries better than any other tool. WCCO’s Natalie Nyhus spoke with a neurosurgeon about how the test works. Concussions are a scary injury because what we see on the outside may not reflect what’s happening on the inside. Doctors have long been able to see how the brain looks.
Now, they can see how it’s working just by tracking eye movement.
“The underlying premise is that when normal people’s eyes are moving, if they are watching television for example, they move with really tight synchrony. When someone has a brain injury, their eyes do not move with tight synchrony. And we can measure that,” Dr. Uzma Samadani said. “We can figure out how badly the eyes are functioning. That tells us something about how well the brain is functioning.”
Dr. Samadani said this technology could soon be used on the sidelines and that we can liken eye tracking and concussions to the way blood tests can diagnose a heart attack.
Important Safety Information
The Visian ICL is intended for the correction of moderate to high nearsightedness. Visian ICL and Visian TICL surgery is intended to safely and effectively correct nearsightedness between -3.0 D to -15.0 D, the reduction in nearsightedness up to -20.0 D and treatment of astigmatism from 1.0 D to 4.0 D. If you have nearsightedness within these ranges, Visian ICL surgery may improve your distance vision without eyeglasses or contact lenses. Because the Visian ICL corrects for distance vision, it does not eliminate the need for reading glasses, you may require them at some point, even if you have never worn them before.
Implantation of the Visian ICL is a surgical procedure, and as such, carries potentially serious risks. Please discuss the risks with your eye care professional. Complications, although rare, may include need for additional surgical procedures, inflammation, loss of cells from the back surface of the cornea, increase in eye pressure, and cataracts.
You should NOT have Visian ICL surgery if:
- Your doctor determines that the shape of your eye is not an appropriate fit for the Visian ICL
- You are pregnant or nursing
- You do not meet the minimum endothelial cell density for your age at the time of implantation as determined by your eye doctor
- Your vision is not stable as determined by your eye doctor
Before considering Visian ICL surgery you should have a complete eye examination and talk with your eye care professional about Visian ICL surgery, especially the potential benefits, risks, and complications. You should discuss the time needed for healing after surgery. For additional information with potential benefits, risks and complications please visit DiscoverICL.com
