Astigmatism refers to that the refractive power of the eyeball on different meridians is inconsistent, or the diopter of the same meridian is different, so that the parallel light entering the eye cannot form a focus on the retina and form a focal line. Clinically, it can be divided into regular astigmatism and irregular astigmatism. The two main meridians with the largest difference in refractive power are perpendicular to each other, which is regular astigmatism. Most of this astigmatism is congenital. Irregular astigmatism is caused by different curvatures of meridians, such as corneal scar, corneal facet, round silver cornea or after some internal and external eye operations.

[Edit this paragraph] Diagnostic points of astigmatism eyes

1. blurred vision, poor near and far vision, the degree of which is proportional to the size of astigmatism.

2. Eye fatigue, hyperopia astigmatism is more obvious. There may be eye swelling, dull eyes, tears, headache, and severe cases may be accompanied by nausea and vomiting.

3. Examined by p 1 acid dish or window reflection method, it was found that the corneal curvature was inconsistent.

4. Fundus: If the astigmatism is high, the optic papilla can be oval.

5. People with high astigmatism often squint to play the role of cracks or pinholes.

[Edit this paragraph] Treatment of astigmatism eyes

1. Mild asymptomatic astigmatism does not need to be corrected.

2. Symptomatic mild astigmatism, high astigmatism or visual impairment must be corrected with a cylindrical mirror.

3. Irregular astigmatism can be corrected with contact lenses.
