I-fluorescein angiography

I-Fluorescein angiography luvavanyo lwamehlo olusebenzisa idayi ekhethekileyo kunye nekhamera ukujonga ukuhamba kwegazi kwi-retina kunye ne-choroid. La ngamacandelo amabini ngasemva kweliso.

Uya kunikwa amathontsi wamehlo enza ukuba umfundi wakho avuleke. Uya kucelwa ukuba ubeke isilevu sakho ekuphumleni kwesilevu kunye nebunzi lakho ngokuchasene nebha yenkxaso ukuze ugcine intloko yakho ihleli ngexesha lovavanyo.

Umboneleli wezempilo uyakuthatha imifanekiso yangaphakathi kweliso lakho. Emva kokuba kuthathwe iqela lokuqala lemifanekiso, idayi ebizwa ngokuba yifluorescein iyafakwa emthanjeni. Rhoqo kuye kufakwe ngaphakathi engqinibeni yakho ngaphakathi. Isixhobo esifana nekhamera sithatha imifanekiso njengoko idayi ihamba kwimithambo yegazi ngasemva kweliso lakho.

Indlela entsha ebizwa ngokuba yi-ultra-widefield fluorescein angiography inokubonelela ngolwazi oluthe kratya malunga nezifo ezithile kune-angiography eqhelekileyo.

Uya kudinga umntu oza kukuqhubela ekhaya. Umbono wakho unokuba mfiliba ukuya kuthi ga kwiiyure ezili-12 emva kovavanyo.

Unokuxelelwa ukuba uyeke ukuthatha amayeza anokuchaphazela iziphumo zovavanyo. Xelela umboneleli wakho malunga nayiphi na i-allergies, ngakumbi impendulo kwi-iodine.

Kufuneka usayine ifom yemvume unolwazi. Kuya kufuneka ususe iilensi zonxibelelwano ngaphambi kovavanyo.

Xelela umboneleli ukuba unokukhulelwa.

Xa kufakwa inaliti, abanye abantu beva iintlungu kancinci. Abanye baziva behlaba nje okanye behlaba. Emva koko, kunokubakho ukuthotywa okuthile.

Xa idayi ijojowe, unokuba ne-nausea encinci kunye nemvakalelo efudumeleyo emzimbeni wakho. Ezi mpawu zihamba ngokukhawuleza ixesha elininzi.

Idayi iya kubangela ukuba umchamo wakho ube mnyama. Inokuba ngumbala o-orenji usuku okanye ezimbini emva kovavanyo.

Olu vavanyo lwenziwe ukubona ukuba ngaba kukho ukuhamba kwegazi okufanelekileyo kwimithambo yegazi kulwahlulo olubini ngasemva kweliso lakho (i-retina kunye ne-choroid).

Ingasetyenziselwa ukuxilonga iingxaki kwiso okanye ukufumanisa ukuba unyango oluthile lwamehlo lusebenza njani.

Iziphumo eziqhelekileyo zithetha ukuba iinqanawa zibonakala zinobungakanani obuqhelekileyo, akukho zinqanawa zintsha zingaqhelekanga, kwaye akukho zithintelo okanye ukuvuza.

Ukuba ukuvaleka okanye ukuvuza kukhona, imifanekiso iya kuyenza imephu indawo yokufumana unyango olunokwenzeka.

Ixabiso elingaqhelekanga kwi-angiography ye-fluorescein inokubangelwa:

• Iingxaki zokuhamba kwegazi (ukujikeleza kwegazi), njengokuvaleka kwemithambo okanye imithambo
• Umhlaza
• Seswekile okanye enye retinopathy
• Igazi elonyukayo
• Ukudumba okanye ukudumba
• Ukonakala kweMacular
• IiMicroaneurysms - ukwandiswa kwee-capillaries kwi-retina
• Amathumba
• Ukudumba kwidiski ye-optic

Uvavanyo lunokwenziwa kwakhona ukuba:

• I-Retinal detachment
• I-Retinitis pigmentosa

Kukho ithuba elincinci losulelo nangaliphi na ixesha ulusu lophukile. Ngokuqhelekileyo, umntu unomdla kakhulu kwidayi kwaye unokufumana:

• Ukuba nesiyezi okanye ukudinwa
• Umlomo owomileyo okanye ukwanda kwamathe
• Imihlathi
• Ukunyuka kwentliziyo
• Incasa yentsimbi emlonyeni
• Isicaphucaphu nokugabha
• Ukuthimla

Ukuphendula kakubi kakhulu kunqabile.

Iziphumo zovavanyo zinzima ukutolika kubantu abaneekati. Iingxaki zokuhamba kwegazi kuboniswe kwi-angiography ye-fluorescein inokucebisa ngeengxaki zokuhamba kwegazi kwamanye amalungu omzimba.
