What are the methods of treating amblyopia? After accurate optometry and wearing glasses to correct refractive errors, the following methods can be used to treat amblyopia: 1. Traditional masking method For patients with amblyopia with ≥ 2 lines of binocular vision difference. Covering the eye with better vision and forcing the amblyopic eye to gaze; 2. Repression therapy For amblyopic patients with ≥ 2 lines of binocular vision difference. Repression therapy is the use of optical or drug temporary inhibition of the healthy eye, so that the healthy eye vision blurred, thus facilitating the enablement of the amblyopic eye, lifting the competitive inhibition of the amblyopic eye, so that the amblyopic eye visual acuity gradually improved. It is divided into near-suppression and far-suppression, and the clinical method of near-suppression is mostly used, i.e., the child’s healthy eye is given 1% atropine eye ointment twice a week to paralyze the ciliary muscle of the healthy eye, which is in a state of loss of regulation and cannot see near objects; 3. Visual stimulation therapy is applied to various types of central gaze amblyopia, especially refractive amblyopia. The use of contrast, spatial frequency of different bars, as a source of stimulation to stimulate the amblyopic eye to improve visual acuity; 4, red light flicker method for paracentral gaze amblyopia. The principle is to use the macular central recess where there are only visual cone cells, which are sensitive to the red light in the spectrum. By moving from the central recess to the periphery, the optic cone cells decrease sharply and the optic rod cells increase gradually. Adding a certain size of red filter in front of the amblyopic eye correction lens makes the gaze area spontaneously shift from the insensitive rod cell area (paracentral gaze area) to the sensitive cone cell area (central gaze area); 5. Posterior image treatment method is applicable to paracentral gaze amblyopia. It is used for paracentral amblyopia. It is done by using strong light to glare the peripheral part of the retina, including the paracentral gaze area, so that it is inhibited; at the same time, the macula is protected from the glare of strong light by blocking it with a black disc. In addition, a black disc is used to protect the macula from glare, thus improving the function of the central sulcus and the nature of the gaze; 6. Visual training is the use of optical or psychophysical methods to improve the ability of adjustment and convergence of amblyopic patients, thus improving the visual quality and visual comfort of patients with refractive amblyopia.
