Amblyopia is the result of an imbalance in the input of stimuli to both eyes and can have a serious impact on a child’s vision development. However, amblyopia is not a terminal disease that cannot be cured. There are more treatments for amblyopia, and its treatment effect is closely related to the age, the younger the age, the better the effect, so early detection is very important for amblyopia treatment. Here, this article will give you a brief introduction to four common methods of treatment for amblyopia. The traditional masking method is still the main and most effective method for the treatment of amblyopia, and is very effective for both central gaze amblyopia and paracentral gaze amblyopia. The masking method removes the inhibition due to the stimulation of the gaze. Children within 1 year of age can be covered to run the day of the healthy eye to prompt the amblyopic eye to gaze, so as to avoid the occurrence of masking amblyopia, and children two years old can use the 1:1 masking rule; children 3-4 years old can be covered for a longer period of time. When reviewing the healthy eye, the mask should be removed for 5 minutes to allow the healthy eye to adapt to the room light and surrounding environment. If the visual acuity of the healthy eye does decrease, it means that covering the amblyopic eye is definitely superior to opening both eyes. Covering the amblyopic eye actively promotes the function of the healthy eye and also prevents the competing effects due to opening both eyes. After the amblyopic eye has achieved the best visual acuity, full-day coverage is replaced by part-time coverage and continuous coverage, which can be terminated after 3 months when the visual acuity of the amblyopic eye no longer continues to improve. In addition to conventional masking, traditional masking plus fine work can be the best effective therapy for amblyopia depending on the age and the improvement of visual acuity of the amblyopic eye. Second, visual stimulation therapy The cortical visual cells of animals and humans respond well to different spatial frequencies, and neurons can adjust sensitively to space. According to this mechanism, the scholars of Cambridge University in England designed a new amblyopia treatment instrument, named CAM (visual stimulator), using the contrast, spatial frequency of different bars as a stimulation source to stimulate the amblyopic eye to improve vision. The best indications for this therapy are central gaze amblyopia and refractive error amblyopia, and the course of treatment can be greatly shortened, but the treatment effect for paracentral gaze amblyopia is poor. The principle of repression therapy is to use corrective or undercorrective lenses and every drop of atropine to repress the function of the healthy eye. The advantage of the drug optical suppression method is that it is not necessary to cover the eye, can prevent masking amblyopia, after wearing the lens can improve the visual acuity of the amblyopic eye, strabismus can be reduced or disappear, also applicable to latent nystagmus, the disadvantage is that the course of treatment is long, high cost, and not as effective as the traditional masking. This method uses strong light to dazzle the peripheral retina of central amblyopia, including the paracentral gaze area, so as to produce inhibition; at the same time, the macula is protected by black garden disk masking, so that it is not dazzled by strong light, and then trained under indoor flash to improve the macular function of amblyopic eyes. However, this method is only applicable to the treatment of paracentral gaze amblyopia.
