What does ultra-high myopia mean?

Ultra-high myopia refers to myopia with a refractive error exceeding 1000 degrees. It is classified as pathological myopia and is closely associated with genetic factors. The axial length of the eye in such cases typically exceeds 28 mm, representing a significant elongation compared to the normal axial length in healthy adults. Patients with ultra-high myopia often experience structural deformation of the eyeball, which may lead to various fundus diseases, including high myopia-related macular degeneration, retinal holes, and retinal detachment. Additionally, these individuals are at higher risk for other ophthalmic conditions such as glaucoma and cataracts. In terms of treatment, implantable collamer lens (ICL) surgery has become a favorable option for vision correction in patients with ultra-high myopia. Regular ophthalmic examinations are also crucial for monitoring and managing potential complications.
