1.What is amblyopia? In the past, amblyopia was called amblyopia when there was no obvious organic pathology in the eye and functional factors were the main cause of far-corrected visual acuity below 0.8 and could not be corrected. In 2010, the Strabismus and Amblyopia Group of the Chinese Academy of Ophthalmology gave a more detailed definition of amblyopia: the best corrected visual acuity of one or both eyes is lower than the corresponding age visual acuity or the difference in visual acuity between the two eyes is more than 2 lines during visual development due to monocular strabismus, uncorrected refractive error and high refractive error and form deprivation. 2.Why does amblyopia occur? Amblyopia is caused by the following conditions: children with strabismus, refractive error (high myopia, hyperopia or astigmatism), in which case the visual acuity does not develop sufficiently during development, resulting in reduced visual function; other pathologies, such as common congenital cataracts, ptosis, etc., when the primary pathology is removed, but the visual acuity cannot reach normal. 3.What is the effect of amblyopia on the child? The danger of amblyopia is that amblyopic patients cannot have perfect stereo vision, which is an advanced visual function unique to humans and higher animals, that is, the ability of their eyes to distinguish objects from the outside world in terms of distance, front and back, depth, concavity and convexity. It is because people have good stereoscopic vision, so that the hands and eyes can be agile and sophisticated cooperation, to complete a variety of complex high-tech work. The quality of stereoscopic vision can directly affect the quality of work and personal safety, so in this sense, amblyopia is far more harmful than myopia, and should attract the attention of the whole society. 4.What is the best age to treat amblyopia? Amblyopia only occurs in early childhood when vision is not yet mature, usually before the age of 6. Because the age is too young, it is not easy to attract parents’ attention, thus delaying timely treatment. The treatment of amblyopia is closely related to the age of the child, the younger the child, the more effective the treatment, and the adult treatment is basically ineffective. 5.What are the treatments for amblyopia? Removal of the cause: glasses should be used to correct refractive errors such as myopia, hyperopia and astigmatism, and surgery should be performed if there is still strabismus after prescription; cataracts and ptosis should be operated on accordingly. Masking therapy, fine vision training, visual stimulation therapy, red filter masking therapy, posterior image therapy, supplementary training, medication – levodopa (Slippa) 6, what are the points of attention for amblyopia treatment? According to the age, condition and condition of the child, various methods of amblyopia treatment should be correctly selected under the guidance of the doctor, and a better treatment plan should be formulated. The implementation of the plan must be strict and thorough, combining hospital treatment and home training, regular review of visual acuity, regular optometry, and understanding of refractive changes (every 3-6 months). After the best results are achieved, close observation and necessary consolidation treatment should be continued. 7.How to detect amblyopia at an early stage? The key to amblyopia treatment is early detection, which requires parents and caregivers to pay attention to the conditions or suspicious signs of amblyopia, and immediately ask a specialist for diagnosis. In cases of difficult birth, prolonged labor, suspected intracranial pressure due to head compression, or retinal hemorrhage, etc. Early after birth, the child has had a history of covering the eyes for more than 5 days and not opening the eyes for many days due to an eye disease or other reasons. For some specific reason, the child’s eyes have been exposed to extreme light stimulation or extreme darkness since birth. Eye disease such as ptosis, corneal clouding or congenital cataracts. Has strabismus since birth, internal and external strabismus after a fall or bruise. When looking forward and backward at an object, the eye appears to tremble horizontally; the behavior is strange, the child struggles to see things than the same age, the toy is held particularly close, and if it is placed a little far away or covers a healthy eye, the child becomes irritable and cries a lot.
