How Vision Therapy Can Help Correct Amblyopia in Children and Adults
Amblyopia, commonly known as "lazy eye," affects nearly every aspect of your life. Reading, playing sports or even concentrating on a task for more than a few minutes become much more difficult when your brain ignores images from one eye. Fortunately, it's possible to correct the condition through vision therapy, even if you're an adult.
What Causes Amblyopia?
Amblyopia can occur as a result of:
What Are the Symptoms of Amblyopia?
If you have amblyopia, you may experience:
Can My Condition Be Treated?
You may have been told that there's no hope for you if you're an adult who suffers from amblyopia. For many years, eye doctors and researchers believed that vision could only be improved if you received treatment for the condition during childhood. In fact, it was once believed that your brain couldn't adapt and change much once you became a teenager.
We know that's not true today. Although amblyopia treatment is most effective when begun in early childhood, teens and adults can experience significant improvements in vision with vision therapy.
Take Sue Barry, for example. Dubbed "Stereo Sue" by neurologist Dr. Oliver Sacks, Sue spent much of her life viewing the world in only two dimensions due to amblyopia. After beginning vision therapy, she was finally able to see in 3D. Therapy spurred her brain to form new neural connections that made 3D vision possible.
In a study conducted at the University of California at Berkeley, adults who had amblyopia noticed an improvement in both 3D depth perception and visual acuity after vision therapy. During the study, they played video games while their "good" eyes were patched.
Vision therapy is also an excellent option for young children who have amblyopia, as it can reduce or eliminate the need to patch the good eye or use drops to blur the vision in the good eye.
What is Vision Therapy and How Can It Help Me?
Vision therapy improves the connection between your brain and eyes. During therapy, you'll participate in games and activities designed to convince your brain to recognize the impulses from your "bad" eye.
Video games may be part of your therapy. One game specifically designed for people who have amblyopia takes advantage of virtual reality technology. Before you play the game, your goggles will be adjusted to decrease the signal strength in your good eye. As a result, your brain will pay more attention to impulses received from the bad eye.
If you have amblyopia, vision therapy can truly change your life. You may finally be able to see clearly, catch a ball, read a few chapters in a book without becoming tired, appreciate 3D movies and judge distances when driving more accurately.
