352 Possible Causes for Astigmatic Refractive Errors

  • Keratoglobus

    A significant decrease was also seen in mean refractive astigmatism which decreased from 5.93 (3.06) D preoperatively to 3.23 (1.14) D (p   0.037).[doi.org] Miscellaneous conditions Astigmatism In this condition, the corneal shape is slightly rugby ball-shaped rather than truly spherical, causing a refractive error.[patient.info] The mean keratometry decreased from 57.54 (SD 6.89) D preoperatively to 46.36 (2.39) D (p   0.003), and the mean spherical equivalent (SEQ) refractive error decreased from[doi.org]

  • Astigmatism

    We examine the components of astigmatism and the research into the prevalence and natural course of astigmatic refractive errors throughout life.[ncbi.nlm.nih.gov] […] blurred vision. edit English astigmatism refractive error characterized by the optics of the eye to focus a point object into a sharp focused image on the retina, has_symptom[wikidata.org] Astigmatism is a refractive condition encountered commonly in clinical practice.[ncbi.nlm.nih.gov]

  • Disorder of Refraction and Accommodation

    When one has a cylindrical error, one has astigmatism. The common refractive disorders are described below.[lenzomem.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] See Astigmatism , Farsightedness , Myopia , Presbyopia . refractive error The dioptric power ( K) of the ametropia of the eye.[medical-dictionary.thefreedictionary.com]

  • Congenital Ptosis

    RESULTS: Among the 78 cases (95 eyes) of congenital ptosis, refractive error was present in 13 cases (16.7%) with astigmatism as the commonest refractive error (8.9%).[ncbi.nlm.nih.gov] One or more of the following abnormalities may accompany ptosis in childhood: astigmatism (refractive error), obstruction of the visual axis (the path that light takes into[aapos.org] The following causes of amblyopia were identified: amblyopiogenic refractive errors: astigmatism or 1 dpt, anisometropia or 1 dpt (79% cycloplegia) and strabismus.[ncbi.nlm.nih.gov]

  • Hyperopia

    Hyperopia (also called “farsightedness”) is a refractive error of the eye (like myopia and astigmatism ).[visualeffects.ca] The refractive error of the right eye was severely overcorrected due to data entry error.[ncbi.nlm.nih.gov] Refractive errors are easily treated with eyeglasses, contact lenses, or refractive surgery — LASIK, PRK, etc.[eyephysicians.com]

  • Ptosis

    One or more of the following abnormalities may accompany ptosis in childhood: astigmatism (refractive error), obstruction of the visual axis (the path that light takes into[aapos.org] The abnormal resting position of the eyelid on the cornea may result in astigmatism (a misshaping of the cornea) or other refractive errors, and is a risk factor for developing[aapos.org]

  • Strabismus

  • 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]

  • Vision Disorder

    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] What are the different types of refractive errors? The most common types of refractive errors are nearsightedness, farsightedness, astigmatism and presbyopia.[nei.nih.gov] Abstract In addition to refractive errors such as myopia and astigmatism, ocular disorders that occur in infants, toddlers, and children may present lifelong problems for[pediatrics.aappublications.org]
