Yintoni iFluorescein Angiography?

I-fluorescein angiography yinkqubo yonyango apho idayi ye-fluorescent ifakwe kwigazi. Idayi ibalaselisa imithambo yegazi ngasemva kweliso ukuze ifotwe.

Olu vavanyo luhlala lusetyenziselwa ukulawula ukuphazamiseka kwamehlo. Ugqirha wakho unokuyalela ukuba aqinisekise isifo, amisele unyango olufanelekileyo, okanye abeke iliso kwimeko yeenqanawa ngasemva kweliso lakho.

Zithini iidilesi zovavanyo

Ugqirha wakho unokucebisa nge-fluorescein angiography ukumisela ukuba imithambo yegazi ngasemva kweliso lakho ifumana ukuhamba kwegazi okwaneleyo. Ingasetyenziselwa ukunceda ugqirha wakho ukuba afumane ukuphazamiseka kwamehlo, njengokuwohloka kwe-macular okanye isifo seswekile.

Ukuhlaziywa kweMacular

Ukonakala kwe-Macular kwenzeka kwi-macula, eyinxalenye yamehlo ekuvumela ukuba ugxile kwiinkcukacha ezilungileyo. Ngamanye amaxesha, ukuphazamiseka kuya kusiba kancinci kangangokuba ungaboni naluphi na utshintsho kwaphela. Kwabanye abantu, kubangela ukuba umbono uwohloke ngokukhawuleza kwaye ukungaboni ngamehlo kwenzeka.

Kuba esi sifo sitshabalalisa umbono wakho ojolise kuyo, sikuthintela ukuba:

• ukubona izinto ngokucacileyo
• ukuqhuba
• kufundwa
• ubukele umabonwakude

I-Retinopathy yeswekile

Isifo seswekile esibangelwa sisifo seswekile sibangelwa sisifo seswekile sexesha elide kwaye sikhokelela kumonakalo osisigxina kwimithambo yegazi ngasemva kweliso, okanye i-retina. Iiphina ziphinda ziguqule imifanekiso kunye nokukhanya okungena kwiliso kwimiqondiso, ethi ke idluliselwe kwingqondo nge-optic nerve.

Zimbini iindlela zokuphazamiseka:

• non-proliferative diabetic retinopathy, ezenzeka kumanqanaba okuqala esi sifo
• ukwanda kwesifo seswekile, esikhula kamva kwaye sibukhali

Ugqirha wakho unokuyalela i-fluorescein angiography ukumisela ukuba ngaba unyango lwezi ngxaki zamehlo luyasebenza.

Amalungiselelo ovavanyo

Kuya kufuneka ulungiselele umntu oza kukuphakamisa aze akuqhubele ekhaya kuba abafundi bakho baya kuncipha ukuya kuthi ga kwiiyure ezili-12 emva kovavanyo.

Qiniseka ukuba uxelela ugqirha wakho phambi kovavanyo malunga nayo nayiphi na imigqaliselo, iziyobisi ezingaphaya kwekhawuntareni, kunye nezongezo zemifuno ozithathayo. Kuya kufuneka uxelele ugqirha wakho ukuba ngaba uxabisa iodine.

Ukuba unxiba iilensi zonxibelelwano, kuya kufuneka uzikhuphe ngaphambi kovavanyo.

Ulawulwa njani uVavanyo?

Ugqirha wakho uya kwenza uvavanyo ngokufaka i-dilation eye eye eye emehlweni akho. Oku kwenza abafundi bakho babe banzi. Bayakukucela ukuba uphumze isilevu nebunzi ngokuchasene neenkxaso zekhamera ukuze intloko yakho ihlale ihleli kulo lonke uvavanyo.

Ugqirha wakho uya kuthi emva koko asebenzise ikhamera ukuthatha imifanekiso emininzi yamehlo akho angaphakathi. Nje ukuba ugqirha wakho agqibe ibhetshi yokuqala yemifanekiso, baya kukunika inaliti encinci emthanjeni engalweni yakho. Le naliti iqulethe idayi ebizwa ngokuba yifluorescein. Ugqirha wakho uya kuthi ke aqhubeke nokuthatha imifanekiso njengoko i-fluorescein ihamba ngemithambo yegazi iye kwi-retina yakho.

Zithini iingozi zovavanyo?

Eyona mpendulo ixhaphakileyo sisicaphucaphu nokugabha. Unokuba nomlomo owomileyo okanye ukwanda kwe-salivation, ukwanda kwentliziyo, kunye nokuthimla. Kwiimeko ezinqabileyo, unokuba neempendulo ezimbi, ezinokubandakanya oku kulandelayo:

• ukudumba kwengqula
• urhwebo
• ubunzima bokuphefumla
• isiqaqa
• ukubanjwa kwe-cardiac

Ukuba ukhulelwe okanye ucinga ukuba ungaba, kuya kufuneka uphephe ukuba ne-fluorescein angiography. Ubungozi kumntwana ongekazalwa abaziwa.

Ukuqonda iziphumo

Iziphumo eziqhelekileyo

Ukuba iliso lakho liphilile, imithambo yegazi iya kuba nemilo kunye nobukhulu obuqhelekileyo. Akusayi kubakho kuvala okanye ukuvuza kwiinqanawa.

Iziphumo ezingaqhelekanga

Iziphumo ezingaqhelekanga ziya kutyhila ukuvuza okanye ukuvaleka kwimithambo yegazi. Oku kunokuba ngenxa:

• ingxaki yokujikeleza kwegazi
• umhlaza
• Ukujonga kwakhona isifo seswekile
• Ukonakala kwemacular
• igazi elonyukayo
• ithumba
• ii-capillaries ezandisiweyo kwi-retina
• ukudumba disc optic

Yintoni onokuyilindela emva kovavanyo

Abafundi bakho banokuhlala benciphisiwe ukuya kuthi ga kwiiyure ezili-12 emva kokuba kwenziwe uvavanyo. Idayi ye-fluorescein inokubangela ukuba umchamo wakho ube mnyama kwaye ube-orenji iintsuku ezimbalwa.

Ugqirha wakho kungafuneka a-odole ngakumbi iimvavanyo zelebhu kunye novavanyo lomzimba ngaphambi kokuba bakwazi ukukunika isifo.
