All About Lazy Eyes Part 1

Has someone told you that one of your eyes are lazy?  Did you think “How rude, my eyes are trying their very best!”   All kidding aside may people are confused about the term Lazy eye and what this means for their vision

Lazy eye is a layman’s term for Amblyopia.  Amblyopia is a childhood condition where the eye itself is very healthy and free of disease, but because of one or a combination of a few key factors the brain chooses to not use that eye.   Since the eye is not used, it does not develop the proper connections in the brain during early childhood development.

Important point :  Amblyopia is a term used when someone has one of the below factors.  It should not be used to describe poor vision where the eyes look fine, because there are some rare eye and brain diseases that can cause poor vision without having any outward signs.  There have been cases of people who actually had a serious disease and it was missed because someone assumed it was amblyopia.

What are the factors that causes the brain to ignore the lazy eye?

1. Anisometropic Amblyopia :   high prescription in one eye : Sometimes the two eyes develop differently and one eye has perfect vision, and the other eye has a prescription (such as taking care of your glassesnearsightedness, farsightedness or astigmatism)  These conditions can be corrected easily with a pair of glasses, but if it is not caught early enough during early childhood, then the blurry vision is much more likely to be permanent.

2. Strabismic Amblyopia : one eye is always turn (in or out) : When the eyes are working together Cute Baby Girlpointing at the same object, they are both sharing the “work”,  When you have Strabismus (turned eye), that eye is in a sense “shut off”, only the eye that is pointing straight ahead is doing the “work”  Again if this is not corrected with prism lenses or surgery during early childhood,  the strabismic eye is not going to fully develop and depending on the severity, it may be left with very impaired vision.

There is so much more to say about amblyopia, but the above are the two main ones that we see, there are other types which I will list briefly below, but these are less common.

Deprivational Amblyopia : occurs if there is an eye lid droop, cataract, or other physical blockage of the vision from entering the eye.

Meridional Amblyopia : caused by high astigmatism if uncorrected at an early age

Bilateral Refractive Amblyopia :  this can occur in both eyes if the prescription of the eyes are very high and uncorrected at an early age.

Well I hope you found this educational post on amblyopia helpful,  remember to schedule an appointment with your optometrist if you suspect you or your family member may have amblyopia.  Part 2 on all about lazy eyes will be posted two weeks from today, March 12th, 2014, and it will be in depth on new and innovative treatments on amblyopia
