What is Anisometropia? - Anisometropia Eye Doctors Atlanta, Georgia
Part of our examination involves measuring children for nearsightedness, farsightedness, and astigmatism. This measurement is called refraction and is very accurate, even in small babies. In measuring your child’s eyes, we will be able to detect if there is any inequality of the refraction between the two eyes, which is called ANISOMETROPIA. Basically, this means that instead of the two eyes having the same amount of nearsightedness or farsightedness as the other, that one eye has a greater amount than the other. It is common for there to be a small difference between the two eyes, and in small amounts, Anisometropia usually does not affect the way the eyes see and does not need to be corrected. Greater amounts of Anisometropia make it very difficult for the children to use their eyes together because the eyes are out of balance with each other. The children will depend on the better eye and will tend not to want to use the other eye. When there is a larger amount of Anisometropia, we commonly prescribe glasses to balance out the two eyes.
Sometimes children with Anisometropia will develop Amblyopia or decreased vision in one eye. Wearing the glasses helps improve the vision, but often patching of the eye with better vision is needed to help the vision improvement in the other eye. With the combination of glasses and the patch, we are very successful in giving the children good vision in both eyes.
Parents frequently ask if glasses will be needed when the children get older. The answer is that it really depends on how much difference there is between the two eyes and what happens as the children grow. We do see children who “outgrow” their glasses, and we also see children who do not need the correction on a long term basis to balance out the eyes. These children are often ideal candidates for wearing contact lenses to keep the eyes balanced and the vision good.
