Amaurosis fugax

I-Amaurosis fugax ilahleko yethutyana yombono kwiliso elinye okanye omabini ngenxa yokunqongophala kokuhamba kwegazi ukuya kwi-retina. Iretina ngumaleko othambileyo wokukhanya kwithishu ngasemva kwamehlo.

Amaurosis fugax ayisiso isifo. Endaweni yoko, luphawu lwenye ingxaki. Amaurosis fugax anokuvela kwizizathu ezahlukeneyo. Isizathu esinye kuxa igazi lijiye okanye iqhekeza lepleyiti livimba umthambo wamehlo. I-clot yegazi okanye i-plaque ihlala ihamba kumthambo omkhulu, njenge-carotid artery entanyeni okanye umthambo osentliziyweni, uye kumthambo wamehlo.

I-Plaque yinto enzima eyenzekayo xa amafutha, i-cholesterol kunye nezinye izinto zakha kwiindonga zemithambo. Izinto zomngcipheko zibandakanya:

• Isifo sentliziyo, ngakumbi ukubetha kwentliziyo okungaqhelekanga
• Ukusetyenziswa gwenxa kotywala
• Ukusetyenziswa kwecocaine
• Seswekile
• Imbali yosapho yokubetha
• Igazi elonyukayo
• Cholesterol ephezulu
• Ukwanda kweminyaka
• Ukutshaya (abantu abatshayayo ipakethi enye ngosuku baphinde babe semngciphekweni wokubethwa yistroke)

I-Amaurosis fugax nayo inokwenzeka ngenxa yezinye iingxaki ezinje:

• Ezinye iingxaki zamehlo, ezinje ngokudumba kwethambo le-optic (optic neuritis)
• Isifo semithambo yegazi ebizwa ngokuba yi-polyarteritis nodosa
• Intloko ye-Migraine
• Ithumba lobuchopho
• Ukwenzakala entloko
• I-Multiple sclerosis (MS), ukudumba kwemithambo-luvo ngenxa yeeseli zomzimba zomzimba ezihlasela inkqubo yeemvakalelo
• Isystemic lupus erythematosus, isifo esizenzekelayo apho iiseli zomzimba zomzimba zihlasela izicwili ezisempilweni emzimbeni wonke

Iimpawu zibandakanya ukulahleka ngesiquphe kombono kwiliso elinye okanye omabini amehlo. Oku kuhlala kuhlala imizuzwana embalwa ukuya kwimizuzu eliqela. Emva koko, umbono ubuyela esiqhelweni. Abanye abantu bachaza ukulahleka kombono njengegrey okanye umthunzi omnyama wehla phezu kwamehlo.

Umboneleli wezempilo uya kwenza uvavanyo olupheleleyo lwamehlo kunye nenkqubo yemithambo-luvo. Ngamanye amaxesha, uvavanyo lwamehlo luya kutyhila indawo eqaqambileyo apho ihlwili libhloka umthambo we-retinal.

Uvavanyo olunokwenziwa lunokubandakanya:

• I-Ultrasound okanye i-magnetic resonance angiography scan ye-carotid artery ukujonga amahlwili egazi okanye i-plaque
• Uvavanyo lwegazi ukujonga i-cholesterol kunye namanqanaba eswekile yegazi
• Uvavanyo lwentliziyo, olufana ne-ECG ukujonga ukusebenza kombane

Unyango lwe-amaurosis fugax luxhomekeke kwisizathu sayo. Xa amaurosis fugax ngenxa yegazi okanye iplagi, inkxalabo kukuthintela ukubetha. Oku kulandelayo kunokunceda ukunqanda ukubetha kwestroke:

• Kuphephe ukutya okunamafutha kwaye ulandele ukutya okusempilweni, okunamafutha asezantsi. Sukusela ngaphezu kwesi-1 ukuya kwezi-2 iziselo ezinxilisayo ngosuku.
• Yenza umthambo rhoqo: imizuzu engama-30 ngosuku ukuba awutyebanga; Imizuzu engama-60 ukuya kwengama-90 ngosuku ukuba utyebe kakhulu.
• Yeka ukutshaya.
• Uninzi lwabantu kufuneka lujolise kuxinzelelo lwegazi olungaphantsi kwe-120 ukuya kwi-130/80 mm Hg. Ukuba unesifo seswekile okanye unestroke, ugqirha unokukuxelela ukuba ujonge uxinzelelo lwegazi olusezantsi.
• Ukuba unesifo seswekile, isifo sentliziyo, okanye ukuqina kwemithambo, i-cholesterol yakho ye-LDL (embi) kufuneka ibe ngaphantsi kwe-70 mg / dL.
• Landela izicwangciso zonyango zonyango ukuba unoxinzelelo lwegazi oluphezulu, isifo seswekile, icholesterol ephezulu, okanye isifo sentliziyo.

Ugqirha wakho unokucebisa:

• Akukho unyango. Unokufuna ukutyelelwa rhoqo ukujonga impilo yentliziyo yakho kunye nemithambo ye-carotid.
• I-Aspirin, i-warfarin (i-Coumadin), okanye ezinye iziyobisi ezinciphisa igazi ukunciphisa umngcipheko wesifo.

Ukuba inxalenye enkulu yomthambo we-carotid ibonakala ivaliwe, utyando lwe-carotid endarterectomy lwenziwa ukususa ukubhloka. Isigqibo sokwenza utyando sisekwe kwimpilo yakho iyonke.

I-Amaurosis fugax yonyusa umngcipheko wesifo.

Fowunela umboneleli wakho ukuba kukho nayiphi na ilahleko yombono eyenzekayo. Ukuba iimpawu zihlala ixesha elide kunemizuzu embalwa okanye ukuba kukho ezinye iimpawu zokuphulukana nombono, khangela unyango ngoko nangoko.
