905 Possible Causes for refractive errors

Show results in: Română

  • Myopia

    However, gene variants identified to date explain less than 10% of the variance in refractive error, leaving the majority of heritability unexplained ("missing heritability[ncbi.nlm.nih.gov] Refractive errors were measured at P35 (age when refractive errors stabilize in mice) using automated infrared photorefractor.[doi.org] A classic twin study was undertaken to assess the contribution of genes and environment to the development of refractive errors and ocular biometrics in a twin population.[ncbi.nlm.nih.gov]

  • Hyperopia

    The 4 groups were matched by initial age on examination and spherical equivalent refractive errors (SER).[ncbi.nlm.nih.gov] "Without" hyperopia was defined as refractive error of 3.25 D or less in the most positive meridian in both eyes.[ncbi.nlm.nih.gov] A number of surgical procedures are used to correct refractive errors, including photorefractive keratotomy, LASIK, and clear lens replacement therapy.[healthcommunities.com]

  • Astigmatism

    What Is Refractive Error?[visionaware.org] Health Conditions and Diseases Eye Disorders Refractive Errors Astigmatism 2 Astigmatism is a condition in which the cornea of the eye is asymmetrically curved, causing out-of-focus[curlie.org] refractive error compared with that in the general population.[doi.org]

  • Disorder of Refraction and Accommodation

    refractive error [rifrak′tiv] a defect in the ability of the lens of the eye to focus an image accurately, as occurs in nearsightedness and farsightedness. refractive error[medical-dictionary.thefreedictionary.com] REFRACTIVE ERRORS SPS Y2-2012 2. WHAT ARE WE GOING TO DO TODAY?[slideshare.net] Online Q&A 7 October 2013 Q: What is a refractive error? A: A refractive error is a very common eye disorder.[who.int]

  • Amblyopia

    Amblyopia developed but responded well to treatment, which involved correction of the refractive error and occlusion therapy.[ncbi.nlm.nih.gov] Stimulus deprivation, strabismus, substantially unequal refractive error, microtropia, and organic causes were ruled out.[ncbi.nlm.nih.gov] Symmetrical refractive error is less likely to lead to amblyopia than unilateral error - eg, in the case of myopia, amblyopia is likely with a symmetrical refractive error[patient.info]

  • Asthenopia

    Refractive errors were classified into various types, and the association between these refractive types and symptoms in asthenopia were explored.[avehjournal.org] The two groups were matched for age and cycloplegic refractive error.[ncbi.nlm.nih.gov] Purpose: To study the prevalence of asthenopia and any association with refractive errors in a clinical setting.[avehjournal.org]

  • Mild to Severe Myopia

    This refractive error differences in patients with mild to moderate to severe myopia. Myopia is a common refractive error, also known as nearsightedness.[ksa.ee] Myopia Myopia is the most common form of refractive error and affects nearly 30% of the U.S. population.[corneatexas.com] error to understand.[corneatexas.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] When refractive errors were compared interocularly, no statistically significant differences were found.[ncbi.nlm.nih.gov] The main outcome measures were relative eyelid ptosis severity, presence and type of strabismus, refractive error, and amblyopia.[ncbi.nlm.nih.gov]

  • Presbyopia

    This study sought to determine the prevalence of refractive error and presbyopia, spectacle coverage and the barriers to uptake of refractive services in people aged 15 years[ncbi.nlm.nih.gov] Refractive Error There are three types of refractive error: myopia, hyperopia, and astigmatism. Myopia or "nearsightedness".[refractivesource.com] Of those screened, 76.2 9.0% of teachers had refractive and/or accommodative error and 57.1 7.6% had uncorrected refractive and/or accommodative error.[ncbi.nlm.nih.gov]

  • Degenerative Myopia

    METHODS: Polarimetric RNFL analysis was done in 41 degenerative myopic eyes of 25 patients with spherical refractive errors between -7.50 and -22.00 D (mean -12.50 D;SD 3.5[ncbi.nlm.nih.gov] Refractive errors are vision problems that happen when the shape of the eye keeps you from focusing well.[icdlist.com] It is believed that pathological myopia, when the refractive error exceeds six dioptres, is caused by an alteration in the development of the eye's posterior segment and different[institutmacula.com]
