Pseudomyopia is not myopia in refractive terms, and its naming is controversial. A portion of children and adolescents present with a myopic state with low normal distance vision and normal near vision, which can be corrected with a concave lens for distance vision. Refractive examination after paralysis of the ciliary muscle with atropine may be as follows: 1. Pseudomyopia: normal far vision is restored after using atropine, the myopic state disappears, and the examined shadow is ortho- or hyperopic. 2, true myopia: no significant change in myopic refraction after using atropine. 3.Mixed myopia: After using atropine, the myopic refractive power is obviously reduced, but it is not regarded as orthopia. The causes of the three cases are different and the treatments are different: 1. Pseudomyopia is functional, caused by regulatory spasm, and the eye axis is normal. It is mostly seen in children and adolescents who are younger, with a shorter onset time and lower refractive error. Pseudomyopia should not wear myopia glasses, and can be restored to normal with rest and proper treatment. 2, true myopia is organic, determined by the elongation of the eye axis, corneal curvature, etc., and no obvious relationship with the regulation. It is mostly seen in older adolescents with longer onset and higher refractive error. True myopia should wear myopic lenses to correct distance vision. 3, mixed myopia is true myopia with pseudomyopia component, both organic changes and functional factors, can be partially improved by treatment, but the need to correct the distance vision with glasses.
