Signs of astigmatism include blurry vision, headaches and eyestrain, according to Mayo Clinic. These signs do not worsen with activities such as reading in poor light or watching a television from a very close range. However, it is advisable to seek immediate medical attention when these signs appear to receive early diagnosis and treatment.
Astigmatism is a vision problem that results from erroneous corneal shape, notes Mayo Clinic. Astigmatism patients are either born with the condition or acquire it through eye diseases, eye injury or eye surgery, and no treatment may be necessary due to its mildness. To diagnose astigmatism, a doctor may first seek information about the symptoms the patient experiences including how long the symptoms have lasted, the severity of the symptoms and conditions that make the symptoms better or worse. The tests that may be applied to diagnose astigmatism include vision tests and keratometry, which measures corneal curvature.
Astigmatism can be treated through corrective lenses or refractive surgery, states Mayo Clinic. While corrective lenses make up for the erroneous corneal curvature to restore proper vision, refractive surgery restores the normal shape of the eye. Types of corrective lenses for astigmatism include contact lenses and eyeglasses. Types of refractive surgery for astigmatism include laser-assisted in-situ keratomileusis and photorefractive keratectomy.
