The difference between true myopia and pseudomyopia

Abstract: when some children can’t see clearly, they like to pull their eyes and pull the canthus skin outward. The principle is to pull the canthus skin outward and press the lens with the skin to make the lens return to normal temporarily., There are two kinds of myopia, namely pseudomyopia and true myopia. Pseudomyopia is different from true myopia in essence., From the perspective of symptoms, pseudomyopia is also blurred far and clear near, but there is no corresponding diopter change during mydriatic optometry. Pseudomyopia can’t see clearly in the distance because people often use their eyes incorrectly, so that the eyes can’t get enough rest, and the lens is also in a thickened state. In this way, the parallel light enters the eye. After the thickened lens is bent, the focus falls in front of the retina, and it is not clear to see things in the distance., The difference between true and false myopia mainly lies in: 1. Whether the vision can be restored naturally. We know that true myopia is an organic change. The eyeball of myopia patients has become myopia and can not naturally restore vision. Because the eyes of people with pseudomyopia have not become longer, as long as they can rest and treat properly, pay attention to eye hygiene and develop good eye habits, they can restore normal vision. This is also the main difference between pseudomyopia and true myopia., 2. If false myopia is not corrected and treated in time, it will develop true myopia after a long time., 3. Different symptoms. Ningbo Eye Hospital experts said that the main symptoms of pseudomyopia are: squinting, frequent blinking, eye rubbing, crooked head, frowning, eye pulling, squint, watching TV often move forward, look far blurred, often make mistakes, inattention and often headache. True myopia is characterized by double shadows, eye pain, headache, nausea and exotropia. In severe cases, there are symptoms such as fundus changes and exophthalmos., How to distinguish true myopia from false myopia?,, There are two kinds of

myopia, namely pseudomyopia and true myopia. Pseudomyopia is different from true myopia in essence.

and

from the perspective of symptoms, pseudomyopia also sees far blurred and near clear, but there is no corresponding diopter change during mydriatic optometry. Pseudomyopia can’t see clearly in the distance because people often use their eyes incorrectly, so that the eyes can’t get enough rest, and the lens is also in a thickened state. In this way, the parallel light enters the eye. After the thickened lens is bent, the focus falls in front of the retina, and it is not clear to see things in the distance.

the difference between true and false myopia mainly lies in:

1. Whether vision can be restored naturally. We know that true myopia is an organic change. The eyeball of myopia patients has become myopia and can not naturally restore vision. Because the eyes of people with pseudomyopia have not become longer, as long as they can rest and treat properly, pay attention to eye hygiene and develop good eye habits, they can restore normal vision. This is also the main difference between pseudomyopia and true myopia.

2. If false myopia is not corrected and treated in time, it will develop true myopia after a long time.

3. Different symptoms. Ningbo Eye Hospital experts said that the main symptoms of pseudomyopia are: squinting, frequent blinking, eye rubbing, crooked head, frowning, eye pulling, squint, watching TV often move forward, look far blurred, often make mistakes, inattention and often headache. And true myopia is that the visual objects have double shadows, eye pain, headache, nausea, exotropia, and in severe cases, there are symptoms such as fundus changes and exophthalmos. How can

and

distinguish true myopia from false myopia?

if you suspect pseudomyopia, you can go to the hospital for eye examination. After mydriasis, optometry was performed after ciliary muscle paralysis. If there was no change in myopia, hyperopia and astigmatic diopter, the visual acuity also improved significantly or returned to normal, indicating the existence of pseudomyopia. Because if it is true myopia and the patient’s eye axis has become longer, there must be corresponding myopia diopter changes after mydriasis and paralysis of ciliary muscle, and the vision will not improve after mydriasis.

early symptoms of myopia:

1. Poor far vision. Compared with those with normal vision, patients with myopia have poor far vision.

2. The AC / a value of myopia is higher and increases with the deepening of diopter.

3. Often feel eye fatigue: some primary and secondary school students often read for a long time, their handwriting will overlap and serial, look up and look at the object in front of them, and have the feeling of vagueness and instability. Some people will have a short ambiguity after looking long or near. The above are caused by eye fatigue, leading to the failure of ciliary muscle regulation, which is also an early symptom of myopia.

4. Perceptual allergy: many people have dry eyes, burning, itching, swelling carbuncle and other symptoms when they are tired. In severe cases, the pain will spread to the deep orbit and even cause migraine. This is because the sensory nerves of the eyes have fatigue, perceptual allergy, so before you. Therefore, this is also the early symptoms of myopia. Patients and friends must pay attention and maintain well.

5. Flying mosquito vision or fly vision. This is a common symptom of myopia, in the form of dots, lines, nets or clouds, as if mosquitoes or flies fly in front of you.

6. Squint and tilt your head. Many myopia patients will improve their eyesight by squinting and tilting their heads. Generally, the appearance of myopia is large, full and protrusion.

7. The early symptoms of myopia are more common when there are astigmatism, anisometropia, or poor general condition, such as heavy eyelids, visual ghosting, deformation, flash, discoloration, photophobia, foreign body sensation in eyes, and inability to read for a long time.

pseudomyopia and true myopia are different in essence. In fact, there are many teenagers who see things indistinctly in the first few months, which belongs to pseudomyopia. If pseudomyopia persists and the eyes can’t rest, it will soon turn into true myopia and real myopia. Therefore, to understand the symptoms of pseudomyopia and do a good job in prevention is the best way to treat true myopia
