Myopia is one of the major causes of blindness in children, and degenerative myopia is one of the major causes of blindness in ophthalmology. As the disease progresses, the eye axis gradually elongates and the eye dilates, leading to ischemic pathological changes such as vitreous clouding and liquefaction, retinal and choroidal atrophy, and macular degeneration, resulting in serious damage to visual function. Posterior scleral consolidation is carried out to treat progressive myopia in children, effectively controlling the development of myopia with better results. Posterior scleral reinforcement is a procedure that uses biologic or non-biologic materials to reinforce the weak area of the sclera at the posterior pole. The reinforcing material is fixed on the posterior scleral surface, acting as a mechanical reinforcement to stop the axial growth of the eye, while thickening the scleral tissue at the posterior pole and improving the local blood supply, thus stopping the progression of pathological myopia and related fundus diseases. Posterior scleral reinforcement has a history of 30 to 40 years and has been performed in most countries around the world, and a large number of patients have been operated on. In Russia, it was carried out early and there are many surgeries. A number of hospitals in China also perform it and it has been proven to be safe and effective. Posterior scleral consolidation is indicated for children aged 7 years or older, with myopia greater than or equal to -6D, annual progression of ≥-1D eye axis ≥25mm, presence of posterior scleral staphyloma and presence of retinal degeneration. Posterior scleral reinforcement is an extraocular procedure in which reinforcing material is cut into various desired shapes, separated from the extraocular muscles through an incision in the bulbar conjunctiva, and placed all the way to the outer surface of the eye where the eye is weakest, usually the posterior pole of the eye and the area with staphyloma is fixed. There are many people who have a recent increase in visual acuity after posterior scleral reinforcement, the increase can be as much as 1-3 lines of visual acuity table visual markers, in fact, this is not really the desired therapeutic effect, this is due to the temporary excitation of the optic polypoidal cells caused by the local stimulation of the surgical implantation and the increase in visual acuity, this increase cannot last and diminishes with the weakening of the stimulation, often 1 This increase does not last and decreases as the stimulation decreases, often returning to the original level after 1 – 3 months. It is worth mentioning that posterior scleral reinforcement is a preventive surgery, so it is advisable to do the surgery early. For the already formed fundus lesions, the pathological damage cannot be eliminated, and even if posterior scleral reinforcement is done, it can only stop its further development. Parents are reminded that if your child’s myopia keeps growing beyond the normal range, it is recommended to have the surgery as soon as possible to avoid delaying the treatment and bringing lifelong regrets to your child.
