The stage of improving the vision of one eye alone Amblyopia is lower than the normal vision of children of the same age due to delayed or stagnant vision development, and the effect of treatment is limited by age, so it is imperative to improve the vision to the normal standard as fast as possible and complete the most basic function of the human eye first – to see clearly. The first stage of review is to see if the visual acuity has improved and how many lines have been improved. When the corrected visual acuity of both eyes reaches the normal standard, the first stage of the task is declared complete, but doesn’t that mean the end of the treatment? Consolidation of immediate results When the corrected visual acuity has reached normal, it is time to move on to the consolidation of visual acuity stage. This stage is no longer the same as the previous stage, where the focus was on the expectation of improved visual acuity, while this stage is about the expectation of stabilization of visual acuity, not improvement of visual acuity. Criteria for complete cure of amblyopia: corrected visual acuity is normal and stable for at least two years. Establish good binocular vision function Binocular vision function has an important significance in our daily life, if stereo vision (highest binocular vision function) and depth perception is lost, it is stereo blindness, many jobs that require fine vision cannot be involved, such as driving transportation, etc. Some professions, such as airline pilots, surgeons, etc. require good stereo vision. In the above stage of improving and consolidating visual acuity, because the function of both eyes cannot be well established due to poor visual acuity, and because the shielded eyes cannot take into account the synergistic ability of both eyes, so the establishment of binocular vision function must be completed in time after the above two stages are completed.
