Abstract:

In China, more than 300 million patients suffer from myopia, where in over 10 million patients have high myopia, and a large part of high myopia belong to pathologic myopia (PM). Its correlated ocular fundus retinopathy has become the first reason causing irreversible blindness. Posterior staphyloma (PS) is the most basic disease in the series of pathological degeneration of myopia, and its causes are still unconcluded. The thinning sclera, resulting from the continuous axial lengthening, synthesis and decomposition disorder of collagen in sclera, cannot resist the intraocular pressure, which may be the main cause of PS. At present, the only treatment measure is posterior scleral reinforcement surgery. Regular observation is needed for PS with no clinical symptoms or with complications. The surgery timing still requires a large number of clinical studies to assess.
