Amblyopia is a condition in which the best corrected visual acuity is lower than normal due to abnormal binocular interaction or form deprivation during the sensitive period of visual development, which can lead to a variety of visual impairments. Amblyopia treatment is based on refractive correction with masking therapy, supplemented by suppression therapy and pharmacotherapy, etc. The common treatment methods are as follows: 1) Refractive correction: Through refractive correction, a clear image can be formed on the retina, which in turn stimulates the patient’s retinal development and plays a role in improving as well as treating amblyopia; 2) Masking therapy: Covering the normal eye can provide proper visual stimulation to the amblyopic eye. 3. Suppression therapy: The use of undercorrected or overcorrected lenses and the ciliary muscle paralyzing drug atropine can suppress the visual function of the primary eye to a certain extent, thus promoting the development of the amblyopic eye and improving visual function; 4. As a precursor of dopamine, levodopa can cross the blood-brain barrier and has an important regulatory role in retinal and visual central functions; 5, afterimage therapy: after using strong light to irradiate human eyes, an afterimage can be formed on the retina, and in the process of afterimage generation, the inhibition in the macular area of the fundus can be eliminated to a certain extent, thus improving visual acuity; 6, red filter method: experiments have proved that cone cells have a different biological response to Different colors of light produce different biological effects, and red filters can only allow red light to pass through, through the color characteristics of the eye cells to make certain adjustments, and then relieve amblyopia; 7, light brush therapy: light brush therapy is also called Hedinger brush, is based on the instantaneous Hedinger brush effect of a form of treatment, through the stimulation of macular cell development, and then improve visual function, improve vision and relieve amblyopia; 8, amblyopia Corrective surgery: For patients with amblyopia caused by congenital abnormal development of the extraocular muscles, vision correction can be performed through amblyopia corrective surgery under the guidance of a doctor.
