Ukubaleka kwamaurosis: yintoni, oyena nobangela kunye nonyango

• Unyango lwenziwa njani

I-amaurosis edlulayo ekwabizwa ngokuba yilahleko yokubonakalayo yethutyana okanye yethutyana, yilahleko, mnyama okanye ukufiphala kombono onokuhlala ukusuka kwimizuzwana ukuya kwimizuzu, kwaye inokubakho kwiliso elinye okanye omabini amehlo. Isizathu sokuba oku kwenzeke kukunqongophala kwegazi eline-oxygen entlokweni nasemehlweni.

Nangona kunjalo, i-amaurosis edlulayo luphawu nje lwezinye iimeko, ezihlala zixinzelelo kunye nohlaselo lwe-migraine, umzekelo, kodwa ezinokunxulunyaniswa neemeko ezinje nge-atherosclerosis, thromboemboli kunye nokubetha (stroke).

Ngale ndlela, unyango lwe-amaurosis edlulayo lwenziwa ngokususa ukuba yintoni unobangela, kwaye ngenxa yeso sizathu, kubalulekile ukuba ufune unyango ngokukhawuleza xa ingxaki iqatshelwe, ukuze unyango olufanelekileyo luqaliswe kunye namathuba okulandelelana kuncitshiswe ukunciphisa ukungabikho kwe-oxygenation kwizicubu.

Izizathu ezinokubangela

Oyena nobangela uphambili we-amaurosis okhawulezileyo kukusilela kwegazi ene-oxygen eninzi kwingingqi yamehlo, eyenziwe ngumthambo obizwa ngokuba ngumzobo we-carotid, kule meko awunakho ukuthwala isixa esifunekayo segazi elinomoya.

Ngokwesiqhelo, amaurosis akhawulezileyo kwenzeka ngenxa yobukho bezi meko zilandelayo:

• Ukuhlaselwa kweMigraine;
• Uxinzelelo;
• Uloyiko;
• Ukopha kweVitreous;
• Uxinzelelo lwexinzelelo;
• Ngaphambili ischemic optic neuropathy;
• Ukuxhuzula;
• I-Vertebrobasilar ischemia;
• IVasculitis;
• Isifo samathambo;
• Isifo semithambo;
• Hypoglycemia;
• Ukusilela kweVitamin B12;
• Ukutshaya;
• Ukuswela ityamine;
• Umonzakalo weCorneal;
• Ukusetyenziswa gwenxa kwecocaine;
• Usulelo nge-toxoplasmosis okanye i-cytomegalovirus;
• I-plasma viscosity ephezulu.

I-amaurosis edlulayo ihlala yexeshana, kwaye ke umbono ubuyela esiqhelweni kwimizuzu embalwa, ukongeza ekungahlali ushiya nayiphi na into elandelwayo, nangona kunjalo kunyanzelekile ukuba ugqirha afunwe nokuba i-amaurosis ihlale imizuzwana embalwa, ukuze kungaphandwa.

Kwiimeko ezinqabileyo, umntu unokubonisa iimpawu ngaphambi kokuba i-amaurosis idlule, kodwa xa isenzeka, kubikwa iintlungu ezinobunzima kunye namehlo arhawuzayo.

Indlela yokuqinisekisa ukuxilongwa

Ukuxilongwa kwe-amaurosis edlulayo kwenziwa ngugqirha oqhelekileyo okanye ugqirha wamehlo ngengxelo yesigulana, uvavanyo lomzimba oluya kujonga ukuba akukho monakalo ubangelwe kukuwa okanye ukubethwa, kulandele uvavanyo lwamehlo ukuze kugcinwe ukwenzakala kwamehlo okunokwenzeka.

Uvavanyo olufana nokubala okupheleleyo kwegazi, iprotheyini esebenzayo yeC (CRP), ipaneli yeepidid, inqanaba leswekile yegazi, i-echocardiogram kunye nokuvavanywa kokujikeleza kwemithambo ye-carotid nako kunokuba yimfuneko, okunokwenziwa nge-doppler okanye i-angioresonance, ukuze kuqinisekiswe ebangele amaurosis kwaye ngale ndlela uqalise unyango olufanelekileyo.

Unyango lwenziwa njani

Unyango lwe-amaurosis edlulayo lujolise ekupheliseni unobangela, kwaye oku kuhlala kwenziwa ngokusetyenziswa kweziyobisi ezinje ngee-antiplatelet agents, antihypertensives kunye ne-corticosteroids, ukongeza kufundo lokutya kwaye, ukuba kukho imfuneko, ukwenza umthambo wokuphelisa ubunzima obugqithisileyo kwaye uqalise ukuziqhelanisa. iindlela zokuphumla.

Nangona kunjalo, kwiimeko ezinzima kakhulu apho umthambo we-carotid uthinteke kakhulu, nokuba kungenxa ye-stenosis, i-atherosclerosis okanye amahlwili, utyando lwe-carotid endarterectomy okanye i-angioplasty inokuboniswa ukunciphisa umngcipheko wokubetha okunokubakho. Jonga ukuba i-angioplasty yenziwa njani kwaye iyintoni na ingozi.
