What is pseudomyopia

Myopia is generally divided into pseudomyopia, true myopia and mixed myopia. Pseudomyopia is caused by excessive use of the eyes, which leads to continuous contraction and spasm of the ciliary muscle, increased thickness of the lens and blurred vision. Pseudomyopia is functional myopia. The use of drugs, acupuncture, ear acupuncture and physical therapy equipment, or the patient's own eye muscle strengthening exercises can relax the muscles, relieve fatigue and restore vision to normal. If pseudomyopia is not relieved in time, the eyeball will be compressed by the tense extraocular muscles for a long time, which will eventually lead to the enlargement of the eye axis and become true myopia.

What are the symptoms of pseudomyopia?

1. Strabismus

The patient experiences eye discomfort when looking into the distance, and the eyes may sway outward when tired or inattentive.

2. Decreased vision and eye fatigue

Its characteristics are obvious decline in vision in a short period of time and easy fatigue. The symptoms will be relieved to a certain extent after sufficient rest.

3. Dry eyes and blurred vision

Its characteristics are unclear farsightedness, clear vision of near objects, double vision, dry eyes, and foreign body sensation, which can be relieved after rest.

What causes pseudomyopia?

1. Bad eating habits

Long-term picky eating and partial eating lead to unbalanced and insufficient nutritional intake, resulting in the body's lack of multiple vitamins such as vitamin A and vitamin E, as well as multiple trace elements such as calcium, iron, and zinc, which can easily induce pseudomyopia.

2. Bad reading and writing habits

When teenagers or children read or write, their eyes are too close to the book or their posture is incorrect, which can easily induce pseudomyopia, such as reading while walking or riding in a car, or reading under strong light.

What tests are needed for pseudomyopia?

1. Fundus examination

Use a slit lamp to examine the fundus and see if there are any leopard-like changes in the fundus, providing follow-up reference for the next step of treatment.

2. Mydriasis optometry

Use atropine eye drops to instill the eye and check the naked eye vision under a pinhole microscope before and after instillation. If the vision increases after dilation of the pupil, it is pseudomyopia.

3. Cloud method optometry

Ask the patient to wear +3.0D spherical lenses for both eyes at the same time and look at distant objects for 3 minutes. Then remove the right lens and check the naked eye vision immediately. Then check the left eye in the same way.

4. Vision test

Ask the patient to stand at the 5m line and take a vision test on the standard eye chart until the patient can no longer see clearly. The vision test can clearly tell the patient's current vision condition and make a preliminary diagnosis of the disease.
