Fluorescein angiography

Fluorescein angiography yog qhov muag ntsuas uas siv cov zas xim tshwj xeeb thiab lub koob thaij duab los saib cov ntshav ntws hauv qhov retina thiab choroid. Cov no yog ob lub khaubncaws sab nraud povtseg sab nraub qaum qhov muag.

Yuav muab cov kua muag rau qhov muag uas ua rau koj cov menyuam kawm ntawv ziab. Koj yuav raug hais kom tso koj lub puab tsaig ntawm lub puab tsaig ntawm lub puab tsaig thiab koj lub hauv pliaj los tawm tsam lub chaw txhawb nqa kom koj lub taub hau tseem nyob thaum sim.

Feem ntau nws tau txhaj rau sab hauv ntawm lub luj tshib. Lub koob yees duab zoo li lub koob yees duab coj cov duab raws li cov zas txav los ntawm cov hlab ntshav hauv koj lub qhov muag.

Cov txheej txheem tshiab hu ua ultra-widefield fluorescein angiography tuaj yeem muab cov ntaub ntawv ntau ntxiv hais txog qee yam kabmob dua li cov mob hlwb li niaj zaus.

Koj yuav xav tau ib tug neeg tsav koj lub tsev. Koj lub zeem muag yuav plooj zuj zus mus txog 12 teev tom qab ntsuas.

Luag yuav kom koj tsis txhob noj tshuaj uas cuam tshuam rau txoj kev kuaj no. Qhia rau koj tus kws kho mob txog kev fab tshuaj, tshwj xeeb cov tshuaj iodine.

Koj yuav tsum kos npe rau daim foos tso cai. Koj yuav tsum tshem tawm lub iav ntsiab muag ua ntej sim.

Qhia tus kws kho mob yog tias koj xeeb tub.

Thaum cov koob tau ntxig, qee cov neeg hnov ​​mob me me. Lwm cov ho hnov ​​mob xwb los sis plev. Tom qab ntawd, yuav muaj qee qhov throbbing.

Qhov kev kuaj ntshav no yog ua tiav los saib seb puas muaj ntshav txaus rau hauv cov hlab ntshav hauv ob txheej hauv qab nraub qaum koj lub qhov muag (tus retina thiab choroid).

Nws kuj tseem siv tau txhawm rau tshawb nrhiav teeb meem hauv lub qhov muag lossis txiav txim siab seb qee qhov kev kho qhov muag ua haujlwm li cas.

Ib qho txiaj ntsig zoo txhais tau hais tias cov hlab ntsha pom lub cev tsis sib xws, tsis muaj cov nkoj tshiab uas tsis muaj qhov txawv txav, thiab tsis muaj qhov thaiv lossis cov to.

Yog tias qhov blockage lossis cov paug tawm tam sim no, cov duab yuav piav qhia qhov chaw nyob rau kev kho mob tau.

Cov txiaj ntsig tsis meej ntawm fluorescein angiography tej zaum vim yog:

• Ntshav txaus (ncig) teeb meem, xws li txhaws ntawm cov hlab ntsha lossis leeg ntshav
• Mob Cancer
• Ntshav qab zib los yog lwm yam retinopathy
• Ntshav siab
• O o los yog edema
• Macular kev puas tsuaj
• Microaneurysms - kev loj hlob ntawm cov hlab ntsha hauv retina
• Lub pob hlav
• Kev pauv ntawm lub optic disc

Qhov sim no kuj tseem yuav ua yog tias koj muaj:

• Retinal kev ua haujlwm
• Retinitis pigmentosa

Muaj qee lub sijhawm me me ntawm kev kis kab mob txhua lub sijhawm ntawm daim tawv nqaij tawg. Tsis tshua muaj, ib tus neeg paub tab dhau ntawm qhov zas xim thiab tej zaum yuav ntsib kev:

• Kiv taub hau lossis tsaus muag
• Qhuav lub qhov ncauj los yog nce salivation
• Khaus Khawb
• Txhawb lub plawv dhia
• Nws yog xim hlau saj ntawm lub qhov ncauj
• Xeev siab thiab ntuav
• Txooj

Tej kev txhaum fab hnyav yog muaj tsawg heev.

Kev ntsuam xyuas tau nyuaj rau kev txhais lus hauv cov neeg uas muaj kab mob qhov ncauj. Cov ntshav ntws teeb meem tso tawm ntawm fluorescein angiography qhia tau teeb meem ntshav ntws tsis txaus rau lwm qhov ntawm lub cev.
