pathological myopia

pathological myopia, a type of severe, progressive nearsightedness characterized by changes in the fundus of the eye, posterior staphyloma, and deficient corrected acuity. Refractive error is greater than −8.00 diopters, and axial length is greater than 32.5 mm. Pathological myopia increases the risk of retinal detachment by affecting the curvature of the crystalline lens.
