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.
Eye exercises used in behavioural vision therapy, also known as developmental optometry, aim to treat problems, including difficulties of visual attention and concentration, which may manifest themselves as an inability to sustain focus or to shift focus from one area of space to another. [citation needed] Some of the exercises use: [citation ...
A corrective lens is a lens worn in front of the eye, mainly used to treat myopia, hyperopia, astigmatism, and presbyopia. The goal is to bring vision up to 20/20 vision or as close to this as possible. Glasses or "spectacles" are corrective lenses worn on the face a short distance in front of the eye.
Animal studies [6] [7] have found nitroglycerin, a vasodilator used to treat angina, relaxes the ciliary muscle and may hold hope for those suffering from spasm of accommodation. Nitroglycerin is currently being investigated as a treatment for glaucoma, and has shown to decrease intraocular pressure and relax the ciliary muscle. According to ...
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.
An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or false
While pinhole glasses are claimed to be useful for people who are both near- and far-sighted, they are not recommended [citation needed] for people with over 6 diopters of myopia. Additionally, pinhole glasses reduce brightness and peripheral vision, [1] [2] and thus should not be used for driving or when operating machinery. [3]
Layers of the eye, with the choroid labelled. Choroidal neovascularization (CNV) is the creation of new blood vessels in the choroid layer of the eye.Choroidal neovascularization is a common cause of neovascular degenerative maculopathy (i.e. 'wet' macular degeneration) [1] commonly exacerbated by extreme myopia, malignant myopic degeneration, or age-related developments.
