I-Fluorescein angiography

I-Fluorescein angiography ukuhlolwa kwamehlo okusebenzisa idayi ekhethekile nekhamera ukubheka ukugeleza kwegazi ku-retina naku-choroid. Lezi yizendlalelo ezimbili ezingemuva kweso.

Uzonikezwa amaconsi wamehlo enza umfundi wakho avuleke. Uzocelwa ukuthi ubeke isilevu sakho ekuphumuleni kwesilevu nasebunzini lakho ngokumelene nebha yokusekela ukuze ugcine ikhanda lakho linganyakazi ngesikhathi sokuhlolwa.

Umhlinzeki wezokunakekelwa kwempilo uzothatha izithombe zangaphakathi kweso lakho. Ngemuva kokuba kuthathwe iqembu lokuqala lezithombe, kujovwa udayi obizwa nge-fluorescein emthanjeni. Imvamisa ijovwa ngaphakathi endololwaneni yakho. Umshini ofana nekhamera uthatha izithombe njengoba udayi uhamba emithanjeni yegazi engemuva kweso lakho.

Indlela entsha ebizwa nge-ultra-widefield fluorescein angiography inganikeza imininingwane eminingi ngezifo ezithile kune-angiography ejwayelekile.

Uzodinga umuntu ozokuhambisa ekhaya. Umbono wakho ungahle ufiphale kuze kufike emahoreni angu-12 ngemuva kokuhlolwa.

Ungatshelwa ukuthi uyeke ukuthatha imishanguzo engathinta imiphumela yokuhlolwa. Tshela umhlinzeki wakho nganoma yikuphi ukungezwani komzimba, ikakhulukazi ukusabela kwe-iodine.

Kufanele usayine ifomu lokuvuma unolwazi. Kufanele ususe amalensi wokuxhumana ngaphambi kokuhlolwa.

Tshela umhlinzeki uma kungenzeka ukhulelwe.

Lapho kufakwa inaliti, abanye abantu bezwa ubuhlungu obuncane. Abanye bazizwa beshaywa noma betinyelwa kuphela. Ngemuva kwalokho, kungahle kube nokushaywa okuthile.

Lapho udayi ujojowe, ungahle ube nesicanucanu nomuzwa ofudumele emzimbeni wakho. Lezi zimpawu zihamba ngokushesha isikhathi esiningi.

Idayi izokwenza ukuthi umchamo wakho ube mnyama. Kungaba nombala wewolintshi usuku noma ezimbili ngemuva kokuhlolwa.

Lokhu kuhlolwa kwenziwa ukubona ukuthi kukhona yini ukuhamba kwegazi okufanele emithanjeni yegazi ezingqimbeni ezimbili ezingemuva kweso lakho (i-retina ne-choroid).

Ingasetshenziselwa futhi ukuxilonga izinkinga esweni noma ukuthola ukuthi izindlela ezithile zokwelapha iso zisebenza kahle kangakanani.

Umphumela ojwayelekile usho ukuthi imikhumbi ivela ngosayizi ojwayelekile, akukho mikhumbi emisha engajwayelekile, futhi akukho ukuvinjelwa noma ukuvuza.

Uma ukuvinjelwa noma ukuvuza kukhona, izithombe zizobeka imephu indawo ukuze uthole ukwelashwa okungenzeka.

Inani elingajwayelekile kwi-angiography ye-fluorescein kungenzeka ngenxa ye:

• Izinkinga zokuhamba kwegazi (ukujikeleza kwegazi), njengokuvaleka kwemithambo noma imithambo
• Umdlavuza
• Isifo sikashukela noma enye i-retinopathy
• Umfutho wegazi ophezulu
• Ukuvuvukala noma i-edema
• Ukwehla kwamakhompiyutha
• Ama-Microaneurysms - ukukhuliswa kwama-capillaries ku-retina
• Izimila
• Ukuvuvukala kwe-disc optic

Ukuhlolwa kungenziwa futhi uma une:

• Ukuhlukaniswa kwe-retinal
• I-retinitis pigmentosa

Kukhona ithuba elincane lokutheleleka noma nini lapho isikhumba siphukile. Imvamisa, umuntu uzwela ngokweqile kudayi futhi angathola:

• Isizungu noma ukuquleka
• Umlomo owomile noma ukwanda kwamathe
• Isifuba
• Ukunyuka kwenhliziyo
• Ukunambitheka kwensimbi emlonyeni
• Isicanucanu nokuhlanza
• Ukuthimula

Ukusabela okweqile komzimba akuvamile.

Imiphumela yokuhlolwa kunzima ukuyihumusha kubantu abane-cataract. Izinkinga zokugeleza kwegazi ezikhonjiswe ku-fluorescein angiography zingaphakamisa izinkinga zokugeleza kwegazi kwezinye izingxenye zomzimba.
