Can pseudomyopia cause astigmatism?
Pseudomyopia generally does not involve astigmatism. Pseudomyopia is caused by ciliary muscle spasm, while astigmatism is due to changes in the curvature of the cornea, or changes in the eyeball itself; these two are not the same. Pseudomyopia can be completely cured with proactive treatment, adequate rest, reducing close-up activities, avoiding eye fatigue, and using eye drops that alleviate ciliary muscle paralysis, such as low-concentration atropine eye drops and digoxin eye drops. If not treated actively, prolonged pseudomyopia can turn into true myopia. True myopia involves elongation of the eye axis, leading to blurred distance vision but clear near vision. Therefore, when this occurs, a proper dilated refraction test should be conducted. (Medication should be used under the guidance of a physician.)
