Amaurosis fugax

I-Amaurosis fugax ukulahleka kwesikhashana kombono kwelinye noma kuwo womabili amehlo ngenxa yokuntuleka kokugeleza kwegazi kuya ku-retina. I-retina ungqimba lwezicubu oluzwela ukukhanya ngemuva kwenhlamvu yeso.

I-Amaurosis fugax ayisona isifo uqobo. Esikhundleni salokho, kuwuphawu lokunye ukuphazamiseka. Amaurosis fugax kungenzeka ngezimbangela ezahlukahlukene. Enye imbangela kulapho ihlule legazi noma ucezu loqwembe luvimba umthambo esweni. Ihlule noma uqweqwe lwegazi kuvame ukusuka emthanjeni omkhulu, njengomthambo we-carotid entanyeni noma umthambo osenhliziyweni, uye emthanjeni esweni.

I-plaque yinto enzima eyakhekayo lapho amafutha, i-cholesterol, nezinye izinto zakha ezindongeni zemithambo. Izici zobungozi zifaka:

• Isifo senhliziyo, ikakhulukazi ukushaya kwenhliziyo okungajwayelekile
• Ukuphuza ngokweqile
• Ukusetshenziswa kwe-cocoaine
• Isifo sikashukela
• Umlando womndeni wesifo sohlangothi
• Umfutho wegazi ophezulu
• I-cholesterol ephezulu
• Ukukhula kweminyaka
• Ukubhema (abantu ababhema iphakethe elilodwa ngosuku baphinda ubungozi bokushaywa unhlangothi)

I-Amaurosis fugax nayo ingenzeka ngenxa yezinye izinkinga ezinjenge:

• Ezinye izinkinga zamehlo, njengokuvuvukala kwe-optic nerve (optic neuritis)
• Isifo semithambo yegazi esibizwa nge-polyarteritis nodosa
• Migraine ikhanda
• Isigaxa sobuchopho
• Ukulimala ekhanda
• I-Multiple sclerosis (MS), ukuvuvukala kwemizwa ngenxa yamaseli omzimba ahlasela isimiso sezinzwa
• Isystemic lupus erythematosus, isifo esizimela lapho amaseli omzimba ahlasela izicubu ezinempilo emzimbeni wonke

Izimpawu zifaka ukulahleka okungazelelwe kombono kwelinye noma kuwo womabili amehlo. Lokhu kuvame ukuhlala imizuzwana embalwa kuya kwemizuzu eminingana. Ngemuva kwalokho, umbono ubuyela kokujwayelekile. Abanye abantu bachaza ukulahleka kombono njengomthunzi ompunga noma omnyama owela phezu kweso.

Umhlinzeki wezokunakekelwa kwempilo uzokwenza ukuhlolwa okuphelele kwamehlo nokwesistimu yezinzwa. Kwezinye izimo, ukuhlolwa kwamehlo kuzoveza indawo ekhanyayo lapho ihlwili livimba khona umthambo we-retinal.

Ukuhlolwa okungenziwa kufaka phakathi:

• I-Ultrasound noma i-magnetic resonance angiography scan yomthambo we-carotid ukuhlola amahlule egazi noma uqwembe
• Ukuhlolwa kwegazi ukuhlola amazinga e-cholesterol namazinga kashukela egazini
• Ukuhlolwa kwenhliziyo, njenge-ECG ukuhlola ukusebenza kwayo kagesi

Ukwelashwa kwe-amaurosis fugax kuncike embangela yayo. Lapho amaurosis fugax kungenxa yegazi noma uqweqwe lwegazi, ukukhathazeka ukuvimbela isifo sohlangothi. Okulandelayo kungasiza ekuvimbeleni isifo sohlangothi:

• Gwema ukudla okunamafutha bese ulandela ukudla okunempilo, okunamafutha amancane. UNGAPHUZI uphuzo oludakayo olwedlula u-1 kuye kwezi-2 ngosuku.
• Vocavoca umzimba njalo: imizuzu engama-30 ngosuku uma ungakhuluphali ngokweqile; Imizuzu engama-60 kuya kwengu-90 ngosuku uma ukhuluphele ngokweqile.
• Yeka ukubhema.
• Iningi labantu kufanele lihlose umfutho wegazi ongaphansi kuka-120 kuya ku-130/80 mm Hg. Uma unesifo sikashukela noma unesifo sohlangothi, udokotela wakho angakutshela ukuthi uhlose ukucindezelwa kwegazi okuphansi.
• Uma unesifo sikashukela, isifo senhliziyo, noma ukuqina kwemithambo yegazi, i-cholesterol yakho ye-LDL (embi) kufanele ibe ngaphansi kuka-70 mg / dL.
• Landela izinhlelo zokwelashwa kukadokotela wakho uma unengcindezi ephezulu yegazi, isifo sikashukela, i-cholesterol ephezulu, noma isifo senhliziyo.

Udokotela wakho futhi angancoma:

• Akukho ukwelashwa. Ungahle udinge ukuvakashelwa njalo ukuhlola impilo yenhliziyo yakho nemithambo ye-carotid.
• I-Aspirin, i-warfarin (i-Coumadin), noma ezinye izidakamizwa ezinciphisa igazi ukunciphisa ingozi yokushaywa unhlangothi.

Uma ingxenye enkulu yomthambo we-carotid ibonakala ivinjiwe, kwenziwa ukuhlinzwa kwe-carotid endarterectomy ukususa ukuvinjelwa. Isinqumo sokwenza ukuhlinza sisekwe nasempilweni yakho yonke.

I-Amaurosis fugax inyusa ingozi yokushaywa unhlangothi.

Shayela umhlinzeki wakho uma kukhona ukulahleka kombono okwenzekayo. Uma izimpawu zihlala isikhathi eside kunemizuzu embalwa noma uma kunezinye izimpawu ngokulahleka kombono, funa usizo lwezokwelapha khona manjalo.
