It is commonly caused by four conditions retinal detachment, glaucoma, macular degeneration, and giant cell arteritis. Retinal detachmentRetinal detachment should be considered if there were preceding flashes or floaters, or if there is a new visual field defect in one eye.[2][3] If treated early enough, retinal tear and detachment can have a good outcome.[2] GlaucomaAngle-closure glaucoma should be considered if there is painful loss of vision with a red eye, nausea or vomiting.[4] The eye pressure will be very high typically greater than 40 mmHg.[5] Emergent laser treatment to the iris may prevent blindness.[4] Macular degenerationWet macular degeneration should be considered in older people with new distortion of their vision with bleeding in the macula.[6][7] Vision can often be regained with prompt eye injections with anti-VEGF agents.[6] Giant cell arteritisGiant cell arteritis should be considered in an older person with jaw claudication, temporal pain, and tiredness.[8] Placing the person on steroids might save both their vision and decrease their risk of stroke.[9] Without treatment a person can quickly go blind in both eyes.[10] References1. ^{{cite web |title=Acute Visual Loss - MEDSKL |url=https://medskl.com/module/index/acute-visual-loss |website=medskl.com |accessdate=23 January 2019}} [https://en.wikipedia.org/w/index.php?title=Wikipedia:MEDSKL/Acute_vision_loss&oldid=879852275 (Video's script with inline references)] {{Eye pathology}}2. ^1 {{cite journal|last1=Fraser|first1=S|last2=Steel|first2=D|title=Retinal detachment.|journal=BMJ clinical evidence|date=24 November 2010|volume=2010|pmid=21406128|pmc=3275330}} 3. ^{{cite web|title=Facts About Retinal Detachment|url=https://nei.nih.gov/health/retinaldetach/retinaldetach|website=National Eye Institute|accessdate=26 July 2016|date=October 2009|deadurl=no|archiveurl=https://web.archive.org/web/20160728001956/https://nei.nih.gov/health/retinaldetach/retinaldetach|archivedate=28 July 2016|df=}} 4. ^1 {{cite web|title=Facts About Glaucoma|url=https://nei.nih.gov/health/glaucoma/glaucoma_facts|website=National Eye Institute|accessdate=29 March 2016|deadurl=no|archiveurl=https://web.archive.org/web/20160328122443/https://nei.nih.gov/health/glaucoma/glaucoma_facts|archivedate=28 March 2016|df=}} 5. ^{{cite book |last1=Simcock |first1=Peter |last2=Burger |first2=Andre |title=Fast Facts: Ophthalmology |date=2015 |publisher=Karger Medical and Scientific Publishers |isbn=9781908541727 |page=25 |url=https://books.google.ca/books?id=q19uDwAAQBAJ&pg=PA25 |language=en}} 6. ^1 {{cite web |title=Facts About Age-Related Macular Degeneration |url=https://nei.nih.gov/health/maculardegen/armd_facts |website=National Eye Institute |accessdate=21 December 2015 |date=June 2015 |deadurl=no |archiveurl=https://web.archive.org/web/20151222151236/https://nei.nih.gov/health/maculardegen/armd_facts |archivedate=22 December 2015 |df= }} 7. ^{{cite book |last1=Brown |first1=Thomas Andrew |last2=Shah |first2=Sonali J. |title=USMLE Step 1 Secrets3: USMLE Step 1 Secrets |date=2013 |publisher=Elsevier Health Sciences |isbn=0323085148 |page=576 |url=https://books.google.ca/books?id=VhPnWdjBw2UC&pg=PA576 |language=en}} 8. ^{{cite web|title=Giant Cell Arteritis|url=https://www.niams.nih.gov/health-topics/giant-cell-arteritis/advanced#tab-symptoms|website=National Institute of Arthritis and Musculoskeletal and Skin Diseases|accessdate=21 October 2017|language=en|date=13 April 2017|deadurl=no|archiveurl=https://web.archive.org/web/20171022033026/https://www.niams.nih.gov/health-topics/giant-cell-arteritis/advanced#tab-symptoms|archivedate=22 October 2017|df=}} 9. ^{{cite web |title=Giant Cell Arteritis |url=https://www.niams.nih.gov/health-topics/giant-cell-arteritis/advanced#tab-treatment |website=National Institute of Arthritis and Musculoskeletal and Skin Diseases |accessdate=19 October 2018 |language=en |date=13 April 2017}} 10. ^{{cite journal |last1=Solomon |first1=Caren G. |last2=Weyand |first2=Cornelia M. |last3=Goronzy |first3=Jörg J. |title=Giant-Cell Arteritis and Polymyalgia Rheumatica |journal=New England Journal of Medicine |volume=371 |issue=1 |pages=50–7 |year=2014 |pmid=24988557 |pmc=4277693 |doi=10.1056/NEJMcp1214825 }} 1 : Blindness |
