Ukunciphisa Ingozi Nokuphatha Ukwelashwa Kwamehlo
Ukulahlekelwa ngeso lengqondo ngaphandle kokuzwa ubuhlungu uphawu oluvame kakhulu lwesifo esithinta iso lakho. I-stroke yamehlo, noma i-anterior ischemic optic neuropathy (AION), yisimo lapho ukugeleza kwegazi kungavinjelwa khona noma kuncishiswe zibe yizicubu ezingxenyeni zangaphambili ze-optic nererve. I-stroke yamehlo ingabangela ukulahleka okungazelelwe kwombono wendawo, umbono ophikisayo, nezindawo eziyimpumputhe embonweni wakho, kanti ngenkathi kungenzeka ukuthi uyesabisa, ukunakekelwa kwezempilo okusheshayo kungavimbela noma kunciphise ukulahlekelwa kombono.
Ingabe Unayo I-Stroke Yeso?
Abantu abane-stroke yamehlo ngokuvamile banikwa isixwayiso esincane. Iningi labantu abane-stroke yeso libona ukulahlekelwa umbono ngeso elilodwa lapho livuka ekuseni, kungekho buhlungu. Abanye abantu babona indawo emnyama noma isithunzi embonweni wabo ochaphazela ingxenye engaphezulu noma ephansi yensimu yabo ebonakalayo. Ezinye izimpawu zihlanganisa ukulahleka kokubukeka okubukwayo nokuzwela ukukhanya .
Ukuhlonza i-Eye Stroke
Uma udokotela wakho esola ukushaywa kweso, uzobukeza umlando wakho wezokwelapha futhi abuze ngesifo senhliziyo nesimo ongase ube nesifo sikashukela , umfutho wegazi ophakeme noma i-cholesterol ephezulu. Umfutho wegazi wakho uzolinganiswa, kanye nensimu yakho ebonakalayo ebonakalayo nasensimini ebonakalayo . Udokotela wakho uyovame ukuhlanza amehlo akho ukuhlola i-nertic optic yakho ne- retina . Udokotela wakho uzophinde ahlole inzwa yakho yokuhlola ukuhlola umbala obala noma mhlawumbe ukuvuvukala kwe-disc.
Iso lakho elijwayelekile lizoqhathaniswa neliso elithintekayo ukuze lithole ushintsho.
Udokotela wakho uzophinde aqaphele ngokucophelela i-ION esebenzayo (isifo esibucayi esithinta i-optic nerve) bese ubuza ngezimpawu ezinjenge-fever, ikhanda, u-scalp tenderness, ubuhlungu bomhlathi, ukulahlekelwa isisindo, ukulahlekelwa ukudla, nokukhathala, ngakho-ke uzimisele ukuxoxa la maphuzu.
Izinhlobo zezigameko
Kuye endaweni yeso lapho ukugeleza kwegazi kuvinjiwe khona noma kuncishisiwe, ukutholakala okulandelayo kungase kwenzeke.
- I-Central Retinal Artery Occlusion (i-CRAO): Lokhu kuvela ngokuvamile kuvele ngokulahlekelwa okungazelelwe, okujulile kweso, ngaphandle kobuhlungu. Kwenzeka ku-retina.
- I-Central Retinal Vein Occlusion (CRVO): Ngokuvamile kubangela ukulahlekelwa okungazelelwe, okungenakubuhlungu okungabonakali okungaba mnene noma okunzima, lokhu kuvinjelwa kwenzeka emgodini we-Retinal lapho ifika khona iso.
- I-Branch Retinal Artery Occlusion (BRAO): Lokhu kuvinjelwa kuvame ukungabi nabuhlungu futhi kwenzeka ngokuzumayo. Isiguli ngokuvamile silahlekelwa umbono wendawo, futhi ngezinye izikhathi umbono ophakathi. Izimbangela ezingezansi zihlanganisa ukwehlisa umthambo we-carotid, umfutho wegazi ophakeme, ukucindezeleka kwe-cholesterol, kanye / noma isifo senhliziyo.
- I-Branch Retinal Occlusion Occlusion (BRVO): Lolu hlobo lokuvimbela lubangela ukuphuma nokugubha phakathi kwe-retinal vein Kungabangela ukunciphisa umbono, ukulahlekelwa kombono wendawo, ukulahlekelwa umbono, noma izindawo eziyimpumputhe. Lolu hlobo lubandakanya iso elilodwa futhi lingabangelwa ukucindezeleka kwegazi noma isifo sikashukela.
Yini Ebangela Ukushaywa Kweso?
Ukushaywa yeso kubangelwa ukuqhuma kabi emithanjeni yegazi okuhlinzekela ingxenye yangaphambili ye-nertic optic. I-nertic optic yi-cable ehlanganisa ubuchopho emehlweni futhi ithwala izigidi zezintambo zomzimba nezinthambo zegazi. Nakuba ukushaywa kweso kungenzeka kusuka ekuvinjisweni okuphelele kwesitsha segazi esondla isisindo somzimba, kuvame ukubangelwa ukungabi nokucindezelwa noma ukuxoshwa kwezicubu.
Ukucindezelwa kwegazi kungashintsha ngokuhambisana nokucindezeleka kweso futhi ukugeleza kwegazi okuvamile kuyancipha. Uma umsoco we-optic nerve kanye ne-oksijeni unikezwa, izicubu ze-nerve zonakalisiwe futhi zilahlekile, okuholela ekulahlekelweni kombono.
Ingabe Usengozini?
Ukushaywa kweso kuvame kakhulu kubantu asebekhulile nabadala. Cishe amaphesenti ayishumi eziguli ezithintekayo nge-anterior ischemic optic neuropathy zingaphansi kweminyaka engama-45. Isifo senhliziyo sifaka ingozi yokuthuthukisa lesi sifo. Kwezinye iziguli ezinezifo zenhliziyo, ukucindezeleka kwegazi kuwela ngokuphawulekayo ngenkathi ulele. Lokhu kugonywa kwegazi okunciphisa ukunciphisa ngokusebenzisa leyo mithwashwane, okwandisa ithuba lokushaywa yeso, ngakho ukunciphisa ingozi yesifo senhliziyo yakho kungasiza kakhulu ukunciphisa ingozi yokushaya isifo.
Abanye odokotela banomuzwa wokuthi imishanguzo emisha, enamandla kakhulu elwa negciwane lengculaza inganciphisa ukucindezeleka kwegazi kakhulu lapho ilele, ibeka abantu engozini yokushaywa yeso, ngakho qiniseka ukuthi nixoxe nodokotela wakho uma unesifo esibi kakhulu futhi esithintekayo. Kungase kube nokukhetha okuhlukile kuwe.
Ezinye izinhlobo ze-optic disc zingaphakamisa ingozi yokushaywa yeso. Amafayili omzimba ahambela ebuchosheni nasezingeni eliphansi lezitho zomzimba kufanele angene ebhokisini elibizwa nge-optic foramen. Uma le mgodi incane kunezilinganiso, i-fibre yezinzwa ingaba yinyene. Lapho begcwele, ingozi yokuthuthukisa ukukhunjulwa iyanda. Yize ubuhlobo obungacaciswanga kahle, abantu abanesifo esiyingozi senhliziyo futhi bathatha isidakamizwa sezidakamizwa basengozini yesifo.
Ukwelapha Isisu Seso
Ama-corticosteroids aboniswe ukwandisa ubuciko obubonakalayo kwezinye izimo zokushaya isifo uma uqala ngokushesha, yingakho kubalulekile ukuvakashela udokotela wakho uma ubona izinguquko ezizenzekelayo embonweni wakho.
Ama-corticosteriods anciphisa ukusizwa kwemikhumbi futhi athuthukise ukuvuvukala nokusabalalisa. Yilawo ukwelashwa okukhethwa ku-AION ngoba kuyingozi yesifo ebonakala ibangelwa ukunciphisa ukugeleza kwegazi nokuvuvukala, okungafani nokuvinjelwa kweqiniso kwesitsha segazi esivela ku-particle encane, noma emboli. Abanye odokotela bangase babeke izidakamizwa ukuze banciphise ukucindezeleka kweso ngamathemba okuthuthukisa ukugeleza kwegazi ukuya emgodini we-optic.
Kuye kwaba nokucwaninga mayelana nokukwazi ukunikeza imithi esebenza njenge-neuro-protection, engase ivuselele izintambo zesibindi emgodini we-optic. Kodwa-ke, abukho ubufakazi obucacile bokuthi lezi zidakamizwa zinikeza noma yiziphi izinzuzo. Okunye ukwelashwa kuhloswe ekulawuleni izinkinga ze-cardiovascular risk, ngakho-ke ukushaywa kweso akukhona kwenye iso, njengoba kunamathuba amaphesenti angu-30 okuzokwenzeka kwelinye ilanga phakathi neminyaka emithathu.
Izwi elivela
Ukushaywa kweso kuyisifo se-iso esibhekene naso. Ukuba nomfutho wegazi ophezulu ne-carotid artery ukwandisa ingozi yokubhekana nokushaywa kweso, ngakho-ke kubalulekile ukuthatha izinyathelo ezidingekayo ukuze uqiniseke ukuthi lezo zimo ziyahlolwa . Uma unesifo esiphuthumayo sombono noma ezinye izimpawu zesifo sohlangothi, xhumana nodokotela wakho ngokushesha. Ukwelashwa okusheshayo kubaluleke kakhulu ekuvimbeleni ukulahleka kombono.
