80 Possible Causes for Astigmatic Refractive Errors, Dyslexia

  • Presbyopia

    Refractive Error There are three types of refractive error: myopia, hyperopia, and astigmatism. Myopia or "nearsightedness".[refractivesource.com] There are several other types of refractive errors: myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.[web.archive.org] Astigmatism Astigmatism is a refraction error of the eye in which there is a difference in degree of refraction in different meridians.[familyeyecare.co.uk]

  • Disorder of Refraction and Accommodation

    When one has a cylindrical error, one has astigmatism. The common refractive disorders are described below.[lenzomem.com] Dyslexia – a specific language-based disorder.[eyevertise.com] Astigmatism : A person with astigmatic refractive error sees lines of a particular orientation less clearly than lines at right angles to them.[en.wikipedia.org]

  • Down Syndrome

    It turns out Ally has dyslexia.[theatlantic.com] Hyperopia (36.9%) was the most frequent refractive error in the group, followed by astigmatism (29.2%) and myopia (24.6%).[dx.doi.org] Achievement of Students With Dyslexia, Journal of Learning Disabilities, 43, 6, (515), (2010).[doi.org]

  • Vision Disorder

    How many children are affected by learning related vision disorders (such as in cases of children with suspected or diagnosed learning disabilities, developmental delays, dyslexia[add-adhd.org] To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common.[northsuburbaneye.com] Book, links, software, videos, etc. to help individuals develop a better understanding of learning disabilities including dyslexia.[optometrists.org]

  • Congenital Anomaly of the Retina

  • Hyperopia

    Hyperopia (also called “farsightedness”) is a refractive error of the eye (like myopia and astigmatism ).[visualeffects.ca] […] chromatic aberrations, accommodative and binocular dysfunction and asthenopia); other specific clinical diseases or conditions (intellectual disability, cerebral palsy, dyslexia[doi.org] The refractive error of the right eye was severely overcorrected due to data entry error.[ncbi.nlm.nih.gov]

  • Eye Muscle Disorder

    The Dyslexia Research Trust (www.dyslexic.org.uk) offers free testing and coloured glasses.[dailymail.co.uk] Astigmatism is refractive error caused by abnormal curvature of the cornea (the clear layer in front of the iris and pupil).[msdmanuals.com] Refractive errors: Any need for glasses, for example, nearsighted (myopic), farsighted (hyperopic), or astigmatism.[pediatricweb.com]

  • Exophoria

    A child with undiagnosed exophoria may be diagnosed with other conditions including: ADHD learning disabilities short attention span issues dyslexia Children with undiagnosed[healthline.com] Refractive error Hyperopia Myopia Astigmatism Anisometropia / Aniseikonia Presbyopia Vision disorders Blindness Amblyopia Leber's congenital amaurosis Diplopia Scotoma Color[worldlibrary.org] Non-Surgical Management Options Of Intermittent Exotropia 1.Spectacle Correction of Refractive Errors: Refractive errors myopia, hyperopia.[squintmaster.com]

Accidental Trauma 67.[elsevier.com] In the multivariable regression model strabismus was associated with GA (OR   0.84 per week; p   0.001), hyperopic refractive error (OR   4.22; p   0.002) and astigmatism[ncbi.nlm.nih.gov] She was having odd problems with letter reversals and I was looking into dyslexia when a friend told me about her son who had the same problem.[visiontherapystories.org]

  • Amblyopia

    DYSLEXIA: (dyslexic). Margaret S.[children-special-needs.org] The most common causes are misalignment of the eyes ( strabismus ) and uncorrected (usually asymmetric) refractive errors (e.g., farsightedness, nearsightedness, or astigmatism[britannica.com] Children with a refractive error (nearsightedness, farsightedness, or astigmatism) will need glasses. Next, a patch is placed on the normal eye.[nlm.nih.gov]
