Symptoms and treatments of amblyopia
There is vision problem called amblyopia or lazy eye among children below six, which always affects only one eye. Its symptoms include eyestrain, overall poor visual acuity, headache, and one-eye squinting. The patient can also realize the fact that his two eyes are not equally functioning.
Trauma, strong uncorrected nearsightedness or farsightedness and strabismus are some of the reasons that may cause amblyopia. People with amblyopia usually have poor central vision in one eye. Potential blindness can be caused if amblyopia is left untreated.
Since the brain turns off the weaker eye, one treatment for amblyopia is vision therapy exercise, which forces the brain to see through the amblyopic eye. The most common application is patching the stronger eye, which may take several hours each day or all day long for weeks. For convenience, children can take use of prosthetic contact lenses, which block vision in the stronger eye while offering natural eye color.
Atropine eye drops can also be placed in the stronger eye and then its vision can be blurred. This way of treatment eliminates the constant vigilance to check the patch. Certain studies have proved that atropine drops have become an effective alternative to patching. The disadvantage of atropine is its broad side effects, including light sensitivity, flushing and potential paralysis.
Since strong uncorrected refractive error can be one of the reasons that cause amblyopia, corrective eyeglasses and contact lenses may be prescribed to treat this vision problem. And sometimes eyeglasses are in a combination of patching.
The best way to treat strabismus-caused amblyopia is surgery, which corrects the problematic muscles.
Early treatment of amblyopia is essential, since it will never disappear naturally and may lead to permanent visual problem as serious as vision loss. And the risk of eye diseases on the stronger eye should also be considered.
