Definition of amblyopia Low vision (not decreased) in one or both eyes due to congenital factors or inadequate visual stimuli (including photopic and morphological) entering the eye during the critical period of visual development, depriving the macula of clear imaging, or unequal visual input from both eyes, causing competition between clear and blurred objects. (From AAO textbook) New standards for amblyopia in China (2009): The lower limit of visual acuity reference value for children aged 3-5 years is 0.5, and 0.7 for 6 years and above; 1.50D difference between spherical lenses or 1.00D difference between column lenses, high number of eyes are prone to amblyopia; similar refractive error in both eyes and hyperopia greater than or equal to 5.00D, or astigmatism greater than or equal to 2.00D increases the risk of amblyopia. (This standard allows many “amblyopic” patients to shed their amblyopia hat, and is an important milestone in the diagnosis of amblyopia in China and international standards) The harm of amblyopia A vision loss, can not be corrected B binocular visual function is not well developed, the loss of fine stereoscopic vision, for the object’s distance and orientation is not accurate judgment. Amblyopia can be treated as long as the age and method of treatment are appropriate, most of the amblyopia can be treated well. Best age: 3 to 8 years old, the younger the age, the better the prognosis. The degree of amblyopia: mild amblyopia is the most effective, moderate amblyopia is the second most effective, and severe amblyopia is the worst. Nature of amblyopia: the highest efficacy for central amblyopia, and the lower the cure rate the further away from the central concave. Amblyopia treatment compliance: this is the key to treatment, the higher the degree of cooperation, the better the treatment effect. Treatment of amblyopia A: proper eyeglasses after dilated pupils and correct photometry; B: masking to train vision, including complete masking and atropine medication to suppress the two classic ways, which we need to be adhered to by patients with amblyopia. C: Stimulation of vision * Visual physiological stimulation therapy * Posterior image therapy * Synoptic machine training * Fine visual acuity training
