Posterior staphyloma (PS), a hallmark lesion of pathological myopia (PM), is defined as a local swelling of the posterior pole of the eyebulb. PS is closely associated with macular hole, retinoschisis, retinal detachment, chorioretinal degeneration and atrophy. At present, the pathogenesis of PS is not completely concluded, and there are no effective methods of prevention and treatment. The understanding of the epidemiology and risks, diagnose and detection methods, classification and grading, pathogenesis and intervention measures of PS can provide clues to the etiology study.
