Comprehensive therapy for ametropic amblyopia in older children

Abstract: most scholars believe that the sensitive period of visual development is before the age of 8. The treatment effect of amblyopia found before this is good, which makes people misunderstand that the cure hope of amblyopia found after the age of 9 is slim and the curative effect is poor., Older children with ametropic amblyopia are often considered to have poor or ineffective treatment, which makes some older children give up the hope of treatment., In order to verify that ametropic amblyopia in older children can also be treated by treatment: there were 34 cases and 34 eyes of amblyopia children diagnosed clinically, including 19 males and 15 females, aged from 9 to 14 years., Among them, 9 eyes were mild amblyopia (0.6 ~ 0.8), L9 eyes were moderate amblyopia (0.2-0.5), and 6 eyes were severe amblyopia (≤ 0.1)., Methods: ① all children were examined after full ciliary muscle paralysis or computer optometry and glasses, all of them were hyperopia ametropia;, ② traditional covering method, covering healthy eyes;, ③ use the red light scintillation amblyopia therapeutic instrument produced by Xi’an Huaya electronics company to treat twice a day for 10 ~ L5 minutes each time; ④ For those with mild amblyopia and vision above 0-4, fine operations such as threading needles (beads), tracing red, picking beans, etc;,

older children with ametropic amblyopia are often considered to have poor or ineffective treatment, which makes some older children give up the hope of treatment.

and

in order to verify that ametropic amblyopia in older children can also be treated through treatment:

and

clinically diagnosed 34 cases and 34 eyes of amblyopia children, 19 males and 15 females, aged from 9 to 14 years.

and

included 9 eyes of mild amblyopia (0.6 ~ 0.8), L9 eyes of moderate amblyopia (0.2-0.5) and 6 eyes of severe amblyopia (≤ 0.1).

methods:

① all children were clinically examined after full ciliary muscle paralysis or computer optometry and glasses, all of them were hyperopia ametropia;

② traditional covering method to cover healthy eyes;

③ use the red light scintillation amblyopia therapeutic instrument produced by Xi’an Huaya electronics company to treat twice a day for 10 ~ L5 minutes each time; ④ For those with mild amblyopia and vision above 0-4, fine operations such as threading needles (beads), tracing red, picking beans, etc;

and

⑤ all children were followed up once every three months, and the mydriatic optometry and glasses were adjusted again in half a year.

results: in 34 eyes of

, L3 eyes were cured (38.2%), 19 eyes were improved (55.9%), and 2 eyes were ineffective (5.8%). The total effective rate was 94.1%. The relationship between the degree of amblyopia and curative effect 9 eyes of mild amblyopia were cured and 2 eyes were improved. In 19 eyes of moderate amblyopia, 5 eyes were cured and 14 eyes were improved. Severe amblyopia was cured in 6 eyes, improved in 3 eyes and ineffective in 2 eyes.

most scholars believe that the sensitive period of visual development is before the age of 8. The treatment effect of amblyopia found before this is good, which makes people misunderstand that the cure hope of amblyopia found after the age of 9 is slim and the curative effect is poor. We combined the conventional amblyopia treatment methods to treat ametropic amblyopia in older children, and the total effective rate was 94.1%, indicating that amblyopia in older children can also be treated.

our experience is that ametropic amblyopia occurs in ametropic patients without corrective glasses, especially hyperopia ametropia. Due to the limited adjustment, the patient can not get a clear image when looking far and near, resulting in amblyopia. Therefore, we should carefully check and eliminate the organic diseases affecting vision, fully mydriatic optometry, and accurately match the glasses according to whether there is strabismus. At the same time, we should insist on optometry once every six months and adjust glasses in time.

and

because the pyramidal cells in the fovea of the macula are most sensitive to the red light at the wavelength of 640nm, the red light is conducive to the conversion from paracentral fixation to central fixation, and improve vision. In recent years, electrophysiological studies have proved that there are three kinds of retinal ganglion cells: X, y and W, which are connected with three kinds of optic nerve fibers: on, off and on-off.

and

scintillation light stimulation can stimulate the ganglion cells corresponding to the three components for many times, improve their nerve excitability, and improve vision. Yang shaomei et al. Showed that the effective rate of red light scintillation method was 84.5%.

covering therapy is one of the most effective methods for the treatment of monocular amblyopia. We completely cover the healthy eyes according to 6:1 all day, and check the vision once every two weeks. When the vision of the healthy eyes decreases, stop covering, and cooperate with tracing, bead piercing, needle piercing and other treatments to promote the improvement of vision.

we observed 34 patients, and the total effective rate was higher than that of single method. It shows that the effect of comprehensive therapy in the treatment of amblyopia is satisfactory. In the treatment, the cooperation between parents and children is very important. Some children do not adhere to covering or wearing glasses because they pay attention to their appearance, do not return to the clinic on time, adjust their glasses in time, etc., which will affect the curative effect and course of treatment.

we believe that we should pay equal attention to and actively treat ametropic amblyopia in older children. The results show that there is a significant correlation between the curative effect of amblyopia and the degree of amblyopia. The heavier the degree, the worse the curative effect. If children over 8 years old can obey the treatment, their eyesight will also improve significantly.
