1. What is amblyopia? Amblyopia is a condition in which the best-corrected visual acuity (i.e., visual acuity with glasses) in one or both eyes decreases below that of normal children of the same age during visual development due to abnormal visual experiences (monocular strabismus, refractive error, high refractive error, and form deprivation), with no organic lesions on eye examination. Amblyopia is a visual development-related disorder. During the critical and sensitive period of visual development, children with amblyopia can recover their visual acuity with proper treatment and training; once the age exceeds this stage, the treatment of amblyopia becomes very difficult. Therefore, the principle of prevention and treatment of amblyopia should be early detection and early intervention. 2.What are the common causes of amblyopia? Refractive error (moderate to high hyperopia, myopia or astigmatism), refractive aberration, constant strabismus in one eye, form deprivation (congenital ptosis, congenital cataract, etc.), and a few unexplained developmental ones. 3.How to detect amblyopia early? Whether reading and writing, watching TV are too close, whether squinting, frowning to look at things, whether one eye is skewed when looking at things, nystagmus, skewed head when looking at things, all these phenomena may be manifestations of amblyopia. Even if no abnormalities are found, amblyopia cannot be completely ruled out. Children should see a pediatric ophthalmologist until they are 3 years old to prevent missing out on treatment. 4.What are the dangers of amblyopia? Not only does amblyopia have low vision in one or both eyes, but it also affects the development of binocular vision and leads to stereo blindness. As an adult, you will be unable to perform jobs that require high stereo vision (driving, sailing, piloting, mapping, microsurgeons, etc.), which will affect your quality of life and job choices. 5.What are the treatment methods for amblyopia? The common methods currently used to treat amblyopia are masking, red light scintillation, Hedinger light brush, visual physiological stimulation therapy, posterior image augmentation therapy, semiconductor laser, VEP autoregulation CD, repression therapy, synoptic machine and home fine work. It is important to choose the appropriate treatment method according to the type of amblyopia and the nature of the patient’s gaze in order to get the best possible treatment effect. 6.How effective is the treatment of amblyopia? The effectiveness of treatment depends mainly on the age at which amblyopia occurs and the age at which it is treated. It is also related to the degree of amblyopia, the type of amblyopia and the nature of gaze of the patient. The younger the age of treatment, the higher the efficacy, while adults have very poor treatment results. During the critical period of visual development (within 3 years of age) and the sensitive period (within 12 years of age), amblyopic children can recover their visual acuity with proper treatment and training.
