Definition】 Amblyopia is a condition in which there is no obvious organic lesion in the eye, or there are organic changes and refractive abnormalities, but there is a decrease in visual acuity and constant correction or correction of visual acuity below 0.9, which can occur in one or both eyes. According to the degree of amblyopia and the nature of gaze, different treatment methods can be chosen as follows: (1) central gaze amblyopia traditional masking method, forcing the amblyopic eye to gaze, and ask to do some training at home such as tracing, threading needles and beads (fine visual work) to promote visual acuity improvement. (2) paracentral gaze amblyopia The methods used are: afterimage therapy grating stimulation therapy (3) red filter therapy (4) suppression therapy [the latest software amblyopia training system] Traditional amblyopia training is boring, the child’s compliance is poor. At present, the ophthalmology department of Gansu Provincial Maternal and Child Health Hospital has introduced the training software, which is supervised by the National Amblyopia and Strabismus Prevention Center and is a key project of the national “Tenth Five-Year Plan” scientific and technological research. It includes visual function assessment system, visual stimulation training, visual fine training, simultaneous vision training, fusion training, stereo vision training, visual skill improvement training, etc., which can fully restore the visual function of both eyes. The treatment principle of vision enhancement】 Because the visual system is an optical information processing mechanism system. From the eye all the way to the brain, the eye is the lens of a camera, capturing visual signals from around us and then transmitting them to a specific location in the brain (visual cortex) where visual information is processed, and the clarity of the image depends on the input signal received through the eye and the visual processing mechanism in the brain. We use the plasticity of the brain’s nervous system to treat amblyopia by activating visual signal pathways through specific visual stimulation and visual learning, correcting and improving the signal processing capabilities of the brain’s nervous system. Clinically, we stimulate the visual channels through various stimulation modes (bar grid, sine wave, slit light, checkerboard grid, spiral line, and even some images of art works and other waveforms and spectra as well as some special visual signals) to enhance the sensitivity and responsiveness of retinal cells to light; supplemented with hand-eye coordination exercises, we can accelerate the conduction speed of visual nerve impulses, thus significantly improving the visual acuity of amblyopic eyes.
