[Analysis of the treatment effect of posterior scleral reinforcement on pathological myopia].

Pathological myopia, a blinding eye disease, is the most common cause of visual impairment in Asian countries. The most obvious features of pathological myopia are the elongation of the eye axis, the appearance of posterior scleral staphyloma, and even degenerative changes in the retina and choroid, resulting in corresponding complications and ultimately leading to marked visual impairment. Controlling the elongated eye axis is a key factor in preventing the complications of pathological myopia. Posterior scleral reinforcement is the main surgical method to delay the elongation of the eye axis and treat the posterior scleral staphyloma. Although most studies have confirmed that posterior scleral reinforcement is effective in delaying axial elongation and treating myopia, some scholars hold negative views on this surgery. This article summarizes the relevant research results of posterior scleral reinforcement surgery in the treatment of pathological myopia, concerning patients' vision, refractive power, eye axis, and corneal curvature, and discusses the effectiveness of the surgery.
