Amblyopia therapeutic apparatus treats and solves nystagmus 1. Parents of nystagmus amblyopia should know that nystagmus is the most serious eye disease because it looks wobbly and can't be fixed at one point. Parents should first understand the following points: 1, nystagmus can't be cured, but their eyesight can be improved: before the age of 2~3, their eyesight can be easily cured to 0.7~0.8, and it is no problem to look at the blackboard when their eyesight reaches 0.5 or above. Therefore, parents should take helping their children improve their eyesight as their main goal; 2. The treatment of nystagmus is a long-term war of resistance: usually it takes 3~4 months for eyesight to rise continuously, and it takes 2~3 years for treatment, so parents must cooperate patiently and slowly improve their children's eyesight; 3, personalized glasses: wear glasses all day, the frame should be stable, the lens should be attached to the eyelashes, the better, the small pieces of the bridge of the nose on both sides should be pressed inward, so that the frame can be placed on the bridge of the nose stably; 4, don't cover your eyes: covering your eyes will shake things even more; 5. More than 3 ~5 generations of high-precision amblyopia instruments should be selected: if economic conditions permit, the best instrument should be selected for treatment. At present, it is best to use the fifth generation compound amblyopia instrument. If the vision is less than 0.2, individualized treatment should be taken. Second, the treatment and solution of nystagmus amblyopia therapeutic apparatus (1) Determine the threshold visual acuity: (1) Cooperatives: Use the low-vision threshold visual acuity chart below 0, 10 to find the threshold visual acuity. Visual targets can be animals, animated characters, fruits or furniture that children like and know. (2) Those who don't cooperate: don't check their eyesight. According to the extremely low vision below 0 and 05, the amblyopia instrument training with customized threshold vision standards can be formulated. (2) amblyopia therapeutic apparatus, a special hood for uncooperative children with low vision, has the following characteristics: 1, and the structure of amblyopia instrument (1) is binocular, which can slow down the aggravation of nystagmus caused by monocular gaze. It can produce parallax stereogram or ignore the difference plan. (2) Eye patch type: It can create an absolutely dark environment for both eyes, so that during training, the eyes are all black and only the icons are bright, thus attracting children to watch and follow the icons actively or passively, and the dark environment can obviously slow down the eye tremor. (3) The prism can change the pupil distance to 40-50mm(4) The sponge pad is thickened and comfortable to wear. (5) Warm and fragrant, without peculiar smell. 2. Design of vision enhancement training icon and color label in amblyopia instrument: (1) can be customized, that is, when the detected low vision or vision cannot be found, the personalized threshold vision enhancement training icon can be customized according to the compromise value of 0 and 05. (2) The threshold icon can be an E-word or a figure that children know or like, such as hands, animals, simple furniture, flowers, fruits or animated characters. The visual angle of the graphic object refers to the international standard visual acuity chart. 3, operation prompt voice design: programmable or manual personalized prompt parents to operate, to ensure the quality of viewing. 3. Modular scheme for reducing tremor 1, mydriasis registration degree 2, binocular vision similarity, limited eye cover, and minimum corneal vertex spacing; 4. Training in dark environment 5. Training in reducing tremor position 6. Eye mask naturally chases light. Training source: Professor Liu Dongguang. com。
