Astigmatism
Astigmatism, unlike normal vision, occurs when the cornea is shaped like a football (more curved in one direction than the other) and often occurs in combination with myopia (nearsightedness) and hyperopia (farsightedness). This causes light to focus in more than one point on the retina, resulting in blurry and distorted vision.
Symptoms of astigmatism:
- Blurry, distorted vision at all distances
Causes of astigmatism:
- Heredity
- Lid swellings such as chalazia
- Corneal scars
- Keratoconus
- Visual stress
Diagnosing astigmatism:
Dr. Mayer can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Dr. Mayer will also check your eye coordination and muscle control, as well as your eyes' ability to change focus. All of these are important factors in how your eyes see.
Treatment of astigmatism:
Glasses, contact lenses and vision improvement therapy are used by many for the treatment of astigmatism. There are a number of vision correction procedures that can surgically reduce or eliminate astigmatism.
