277 Possible Causes for Astigmatic Refractive Errors, Blurred Vision

  • Astigmatism

    vision.[wikidata.org] 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] Both the types of astigmatism cause blurred vision. Blurring of vision can be more in one direction that can be either diagonally, horizontally or vertically.[symptoma.com]

  • Disorder of Refraction and Accommodation

    […] but blurry close up Presbyopia - inability to focus close up as a result of aging Astigmatism - focus problems caused by the cornea The most common symptom is blurred vision[icdlist.com] When one has a cylindrical error, one has astigmatism. The common refractive disorders are described below.[lenzomem.com] Symptoms of insufficiency Asthenopia Blurred vision for near work (? distance) Over- or under-convergence Investigation of insufficiency Exclude...[academy.org.uk]

  • Hyperopia

    Hyperopia develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision.[web.archive.org] Hyperopia (also called “farsightedness”) is a refractive error of the eye (like myopia and astigmatism ).[visualeffects.ca] These findings were responsible for the blurred vision that was reversed by chalazion resolution or removal.[ncbi.nlm.nih.gov]

  • Congenital Ptosis

    vision.[drfountain.com] 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]

  • Keratitis

    Abstract A 36-year-old HIV-positive man presented with symptoms of redness, blurred vision and foreign body sensation in his right eye for 3 months.[ncbi.nlm.nih.gov] Two-thirds of Americans with myopia also have astigmatism. Refractive errors are usually corrected by eyeglasses or contact lenses.[web.archive.org] One week after discontinuation of the instillation, she presented with blurred vision in her left eye with KPs and multiple stellate keratitis.[ncbi.nlm.nih.gov]

  • Pterygium

    CASE REPORT: A 49-year-old man presented with blurring vision in the left eye. The patient had undergone PRK in both eyes at another surgical center 11 months prior.[ncbi.nlm.nih.gov] Note that pterygium removal can cause astigmatism, especially in people who already have this refractive error.[wespecialeyes.com] Other symptoms include redness or inflammation, blurred vision, dryness, irritation, burning or having a gritty feeling.[yoursightmatters.com]

  • Keratoglobus

    .  A 35-year old male patient with known history of bilateral keratoglobus presented to the hospital with pain, photophobia and blurred vision in his left eye  Best corrected[slideshare.net] 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] Case Presentation A 29-year old male patient with known history of bilateral keratoglobus presented to the Cornea Clinic with pain, photophobia and blurred vision in his right[scirp.org]

  • Cataract

    A 37-year-old woman presented with progressively blurred vision in the right eye after a transient fever 10 months ago.[ncbi.nlm.nih.gov] If an implant lens is not used, or there is remaining refractive error (e.g., astigmatism that is uncorrected by the implant lens), the patient may need to wear either a contact[bestpractice.bmj.com] A cataract is a clouding of the lens in your eye, which causes blurred vision.[eyeinstitute.co.nz]

  • Meibomian Cyst

    Blurred vision may be encountered with larger meibomian cysts, while pain is almost always absent.[symptoma.com] refractive error due to mechanical effects on the cornea [6] Contraindications Inflamed chalazion (hordeolum internum) is an absolute contraindication.[emedicine.medscape.com] If the chalazion persists causing blurred vision, then they can be removed surgically under local anaesthetic.[rotoruaeyes.co.nz]

  • Presbyopia

    The near portion will blur the distance vision slightly and the distance portion will blur near a little.[mastereyeassociates.com] 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]
