Kuyini i-Fluorescein Angiography?

I-angiography ye-fluorescein inqubo yokwelashwa lapho kufakwa khona idayi ye-fluorescent egazini legazi. Idayi iqhakambisa imithambo yegazi ngemuva kweso ukuze ithwetshulwe.

Lokhu kuhlolwa kuvame ukusetshenziselwa ukuphatha ukuphazamiseka kwamehlo. Udokotela wakho angayiyala ukuze aqinisekise ukuxilongwa, anqume ukwelashwa okufanele, noma aqaphe isimo semikhumbi engemuva kweso lakho.

Lokho Ikheli Elihlola Likukhuluma

Udokotela wakho angancoma i-fluorescein angiography ukuthola ukuthi imithambo yegazi engemuva kweso lakho ithola ukugeleza kwegazi okwanele yini. Ingasetshenziswa futhi ukusiza udokotela wakho ukuxilonga ukuphazamiseka kwamehlo, njengokuwohloka kwe-macular noma i-retinopathy yesifo sikashukela.

Ukuguqulwa Kwama-Macular

Ukwehla kwe-Macular kwenzeka ku-macula, okuyingxenye yeso ekuvumela ukuthi ugxile emininingwaneni emihle. Kwesinye isikhathi, lesi sifo siba sibi kakhulu kangangokuba ungaboni ushintsho nakancane. Kwabanye abantu, kubangela ukuthi umbono wehle ngokushesha futhi ubumpumputhe emehlweni womabili bube khona.

Ngoba lesi sifo sonakalisa umbono wakho ogxile, ophakathi, sikuvimbela kusuka:

• ukubona izinto ngokucacile
• ukushayela
• kuyafundwa
• ukubukela ithelevishini

I-Retinopathy Yesifo Sikashukela

I-retinopathy yesifo sikashukela ibangelwa yisifo sikashukela sesikhathi eside futhi iholela ekulimaleni unomphela emithanjeni yegazi engemuva kweso, noma i-retina. Izithombe eziphinda ziguqulwe ziphinde ziguqule izithombe nokukhanya okungena esweni kube amasiginali, bese kudluliselwa ebuchosheni ngenzwa ye-optic.

Kunezinhlobo ezimbili zalesi sifo:

• i-non-proliferative diabetic retinopathy, eyenzeka ezigabeni zokuqala zesifo
• i-retinopathy ekhulayo yesifo sikashukela, ekhula ngokuhamba kwesikhathi futhi iba nzima kakhulu

Udokotela wakho angaphinde ayalele i-fluorescein angiography ukunquma ukuthi ukwelashwa kwalezi zinkinga zamehlo kuyasebenza.

Ukulungiselela Isivivinyo

Kuzodingeka uhlelele umuntu ozokulanda futhi akuhambise ekhaya ngoba abafundi bakho bazonwetshelwa kuze kube ngamahora ayi-12 ngemuva kokuhlolwa.

Qiniseka ukuthi utshela udokotela wakho ngaphambi kokuhlolwa mayelana nanoma yimiphi imiyalo, imishanguzo yamakhasimende, kanye nezengezo zamakhambi ozithathayo. Kufanele futhi utshele udokotela wakho uma unegciwane ku-iodine.

Uma ugqoka amalensi wokuxhumana, uzodinga ukuwakhipha ngaphambi kokuhlolwa.

Siphathwa Kanjani Isivivinyo?

Udokotela wakho uzokwenza isivivinyo ngokufaka amaconsi ejwayelekile e-dilation emehlweni akho. Lokhu kwenza abafundi bakho bavuleke. Bazobe bekucela ukuthi uphumule isilevu nesiphongo sakho ezisekelweni zekhamera ukuze ikhanda lakho lihlale linganyakazi kulo lonke uvivinyo.

Udokotela wakho uzobe esesebenzisa ikhamera ukuthatha izithombe eziningi zeso lakho langaphakathi. Lapho nje udokotela wakho eseqedile iqoqo lokuqala lezithombe, bazokunikeza umjovo omncane emthanjeni engalweni yakho. Lo mjovo uqukethe udayi obizwa nge-fluorescein. Udokotela wakho uzoqhubeka nokuthatha izithombe njengoba i-fluorescein ihamba ngemithambo yegazi iye kwi-retina yakho.

Ziyini Izingozi Zesivivinyo?

Ukusabela okuvame kakhulu isicanucanu nokuhlanza. Ungaba nomlomo owomile noma ukhuphuke amathe, ukhuphuke ukushaya kwenhliziyo, nokuthimula. Ezimweni ezingavamile, ungahle ube nokusabela okweqile okwedlulele, okungafaka okulandelayo:

• ukuvuvukala komphimbo
• isifuba
• ukuphefumula kanzima
• ukuquleka
• ukuboshwa kwenhliziyo

Uma ukhulelwe noma ucabanga ukuthi kungenzeka, kufanele ugweme ukuba ne-fluorescein angiography. Izingozi enganeni engakazalwa azaziwa.

Ukuqonda Imiphumela

Imiphumela Ejwayelekile

Uma iso lakho liphilile, imithambo yegazi izoba nokuma nosayizi ojwayelekile. Ngeke kube khona ukuvinjelwa noma ukuvuza emikhunjini.

Imiphumela Engavamile

Imiphumela engajwayelekile izoveza ukuvuza noma ukuvimba emithanjeni yegazi. Lokhu kungabangelwa:

• inkinga yokujikeleza kwegazi
• umdlavuza
• i-retinopathy yesifo sikashukela
• ukonakala kwe-macular
• umfutho wegazi ophakeme
• isimila
• ama-capillaries akhulisiwe ku-retina
• ukuvuvukala kwe-disc optic

Ongakulindela Ngemuva Kokuhlolwa

Abafundi bakho bangahlala benwetshiwe kuze kufike emahoreni ayi-12 ngemuva kokwenziwa kovivinyo. Idayi ye-fluorescein nayo ingadala ukuthi umchamo wakho ube mnyama futhi ube olintshi izinsuku ezimbalwa.

Udokotela wakho kungadingeka a-ode izivivinyo eziningi zebhu kanye nezivivinyo zomzimba ngaphambi kokuba bakwazi ukukunikeza ukuxilongwa.
