Ohio Eye Care: Understanding Astigmatism
- Posted on: Apr 18 2013
Ideally, your cornea is perfectly circular in shape. In individuals with astigmatism, the cornea isn’t perfectly spherical which could heavily influence its function to direct light into your retina. Dr. Phillip Roholt is an astigmatism specialist in Ohio who has mastered the techniques of astigmatism correction for the past 20 years.
What is astigmatism?
Sufferers of astigmatism have problems looking at objects up close or from a distance. It could accompany nearsightedness or farsightedness. Mild cases are often not noticeable while the most extreme ones could cause objects to appear blurry, whichever the distance. It is estimated that 80 percent of Americans have astigmatism but some of these cases do not require correction.
What causes astigmatism?
While its single cause is not determined yet, experts believe that astigmatism is already present at birth and genetics may be one of the factors contributing to the abnormal shape of the cornea. In rare cases, astigmatism could develop from head traumas or may result from previous eye surgeries.
What are its signs and symptoms?
As mentioned earlier, earlier stages of astigmatism do not have symptoms such as watery eyes, redness, and pain. The severe cases usually present themselves with fluctuating vision, headaches, and eye fatigue, particularly after reading and staring at the computer screen for a long time.
How is astigmatism diagnosed?
Astigmatism is diagnosed with a standard eye test and a refraction exam. For detailed results, additional testing may be required such as corneal topography.
