Scleral reinforcement, generally referred to as posterior scleral reinforcement, has been shown to be clinically and theoretically effective, although it is currently used less clinically, as a method of mechanically controlling ocular axis growth and myopia growth. Posterior scleral reinforcement, is mainly used in cases of myopia where rapid growth of the eye axis produces very high degrees of myopia. Excessive and rapid growth of the eye axis can lead to various complications such as retinal choroidal detachment at the back of the eye, fundus hemorrhage, etc. This method may be considered in order to alleviate the various complications after attempting to adjust the habits of the life and myopia correction to prevent and control the progression of the eye axis. Posterior scleral reinforcement, although it can play a certain role in controlling the progression of the ocular axis and reducing the related complications, it is generally less commonly used in clinical practice because it is an invasive treatment modality, which will have a certain impact on the visual acuity and visual function as well as the anatomy of the eye. It is recommended that specific comprehensive prevention and treatment methods for controlling the progression of the myopic eye axis should be chosen appropriately under the guidance of professional advice.
