Astigmatism is a pathological refraction, radically violating the sphericity of the cornea. In broad terms, this disease can be defined as the distortion of objects that a person sees around him. All pictures become cloudy, and the points they turn to the segments. Ill see people can both at close and far distances. Complications occur, visible objects can not be true. For example, a circle may appear an oval, a square circle, and some objects are absolutely indistinguishable.
Causes and diagnosis of astigmatism
Astigmatism can be congenital or acquired. Most often this disease occurs at birth. In most cases, the defect is not practically makes itself known to a certain degree of development. Sometimes the astigmatism has no effect on vigilance of the person. The disease manifests itself in the deterioration of visibility of the contours of objects.
To diagnose astigmatism help additional symptoms. Even if vision is not deteriorating, headaches, and my eyes start to get tired quickly with minimal stress. On examination, the doctor examines the eye condition of the cornea and lens. Violation of their forms indicates the presence of astigmatism.
During examination of the patient necessarily carried out two procedures – conduct of skiascopy and monitoring the dilation of the pupils with the help of the drug atropine. Based on analyses, the doctor makes a diagnosis and selects the appropriate method of treatment.
Theoretically astigmatism have with each person. The difference is that in some people it develops, and the other is always at the same level and does not affect the General condition or vision.
