Myopia is divided into true and false. How to prevent false myopia from becoming true myopia

Abstract: pseudomyopia friends should eat more foods containing more zinc. Foods such as soybeans, almonds, laver, kelp, mutton, yellow croaker, milk powder, tea, meat, beef and liver contain more zinc and chromium, which can be increased appropriately.

can’t see the words on the blackboard? The line of sight began to blur? Does it mean myopia? Do you have to get glasses quickly? Don’t worry. Myopia can be divided into true and false. Some are false myopia and some are true myopia. How to distinguish the two? Look at the differential diagnosis below.

there are three methods for differential diagnosis of true and false myopia:

(1) Ciliary muscle paralysis: relax the ciliary muscle with ciliary muscle paralysis medicine, make the ciliary muscle relax, make the eye in a static refractive state, and then check the visual acuity and optometry for confirmation. Use 1% atropine eye drops 1 ~ 2 times a day for 3 ~ 4 days; or 2% post atropine or 0.5% tropicamide once every 5 ~ 15 minutes, a total of 6 times. Check the naked eye visual acuity under the eyeglass before and after dropping. If the visual acuity is poor after mydriasis Become true myopia and increase visual acuity to false myopia; The diopter with myopia is true, and the diopter without myopia is false. This is recognized as the most reliable method of differential diagnosis.

(2) cloud method: let the patient wear + 3.0d spherical lens at the same time, look at the distant object for 3 minutes, then remove the right lens, and immediately check the naked eye vision. Those with improved vision are false and those without improved vision are true; then check the left eye with the same method. This method is not accurate.

(3) Dynamic ophthalmoscopy: without mydriasis, ① check the far and near naked vision of both eyes. The eye diseases with poor far vision, normal near vision and no other eye diseases affecting vision are the identification objects. ② the doctor and the patient sit face to face in the dark room. ③ the patient wears a test frame and puts + 2.25d spherical lenses in both left and right eyes. ④ the patient’s eyes look at the visual mark on the ophthalmoscope at the same time (No. 5 characters or characters with few strokes such as large, small, upper and lower shall be pasted on the side of the reflector and illuminated by the slit light near the photoreceptor); ⑤ perform in-situ dynamic detection at a distance of 33cm.

Results: ① the patients with reverse movement in all radial directions were true myopia. ② Each radial direction is clockwise or stationary, or one radial clockwise and the other radial stationary is frontal or hyperopia. Because its performance is myopia, it is pseudomyopia; ③ Mixed astigmatism occurs when one radial direction is reverse movement and the other radial direction is forward movement or immobility. How can

and

prevent false myopia from becoming true myopia?

1. Nutrition is balanced and chromium and zinc are supplemented. Friends with pseudomyopia should eat more foods containing more zinc. Foods such as soybeans, almonds, laver, kelp, mutton, yellow croaker, milk powder, tea, meat, beef and liver contain more zinc and chromium, which can be increased appropriately.

2. How to eliminate pseudomyopia and improve the learning environment

reading and writing should keep a distance of 30 cm at any time and have a correct posture. Pay attention to natural light and ensure adequate indoor lighting. Combine work and rest, get rid of bad learning habits, and rest for 8 ~ 10 minutes every half an hour.

3. Stimulate the visual center and improve visual function.

DC treatment of myopia, ear acupuncture, plum blossom acupuncture, empty massage, acupoint conduction, Qigong therapy and cold water bath therapy. It mainly increases the excitability of the visual center and optic nerve cells of the brain, which can improve the far and near vision. (you should go to a regular eye hospital for treatment)

4. Relax and adjust

① mydriasis therapy. Apply cycloplegic agent to mydriasis. You can use eye drops once a day.

② wearing convex lens method. First, let the patient wear a convex lens with a higher degree, watch the vision meter at 5 meters away, relax the ciliary muscle, then adjust the degree of the convex lens, so that the eyesight is basically normal.

③ overlooking method. After studying or writing for 1 ~ 2 hours, overlook the natural scenery to relax the ciliary muscles.
