Pathologic Myopia and Retinal Detachment
Pathologic myopia (PM) is described as myopia accompanied by excessive axial elongation of the globe and characteristic degenerative changes in the posterior segment, with posterior staphyloma as an important hallmark lesion. Myopia is a complex disease and the etiology of myopia is not clearly understood. The pathogenesis of pathologic myopia is possibly related with biomechanics. It is believed that the excessive elongation of the globe and sclera staphyloma are the most important factors in the development of these degenerative changes in pathologic myopia. Rhegmatogenous retinal detachment is a commom complication of pathologic myopia.
