Pathologic Myopia Site

Posterior Staphyloma —a localized bulging of the back of the eye wall—is considered a definitive sign of PM. Common Complications

Pathologic myopia (PM), also known as degenerative myopia, is a severe form of nearsightedness characterized by excessive elongation of the eyeball (axial length) that leads to structural changes in the posterior segment of the eye . Unlike standard myopia, which can typically be corrected with lenses, pathologic myopia involves progressive and irreversible damage to the retina, choroid, and sclera, making it a leading cause of blindness worldwide, particularly in East Asian countries. Definition and Key Characteristics Pathologic Myopia

Generally defined as a refractive error of diopters or an axial length of ≥26.5is greater than or equal to 26.5 Posterior Staphyloma —a localized bulging of the back

Defined by the International Myopia Institute (IMI) as high myopia accompanied by structural changes such as posterior staphyloma, myopic maculopathy, or optic neuropathy. Definition and Key Characteristics Generally defined as a

While often confused with "high myopia," pathologic myopia is distinct because it involves specific degenerative lesions rather than just a high refractive error.
