In many cases, myopia will stabilize once the growth process has been completed, but in more severe chronic cases, loss of vision can occur. Degenerative myopia, also known as malignant, pathological, or progressive myopia, is characterized by posterior sclera elongation and thinning (at least 25.5 mm to 26.5 mm) and high refractive errors of ...
Low myopia usually describes myopia between −0.50 and −3.00 diopters. [65] Moderate myopia usually describes myopia between −3.00 and −6.00 diopters. [65] Those with moderate amounts of myopia are more likely to have pigment dispersion syndrome or pigmentary glaucoma. [84] High myopia usually describes myopia of −6.00 or more.
The Bates method is an ineffective and potentially dangerous alternative therapy aimed at improving eyesight.Eye-care physician William Horatio Bates (1860–1931) held the erroneous belief that the extraocular muscles caused changes in focus and that "mental strain" caused abnormal action of these muscles; hence he believed that relieving such "strain" would cure defective vision.
Spherical aberration exacerbates myopia in low light (night myopia). In brighter conditions, the pupil constricts, blocking the more peripheral rays and minimizing the effect of spherical aberration. As the pupil enlarges, more peripheral rays enter the eye and the focus shifts anteriorly, making the patient slightly more myopic in low-light ...
Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness). It was developed in 1974 by Svyatoslav Fyodorov, a Russian ophthalmologist. It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy, LASIK, Epi-LASIK and the phakic intraocular lens. [1]
