Fluorescein angiography

Fluorescein angiography ke teko ea mahlo e sebelisang dae e khethehileng le kh'amera ho sheba phallo ea mali ho retina le choroid. Tsena ke likarolo tse peli tse ka morao ea leihlo.

U tla fuoa marotholi a mahlo a etsang hore seithuti sa hao se phutholohe. O tla kopuoa ho beha seledu sa hao phomolong ea selelu le phatleng ea hao khahlano le bareng ea tšehetso ho boloka hlooho ea hau e khutsitse nakong ea tlhahlobo.

Mofani oa tlhokomelo ea bophelo o tla nka litšoantšo tsa kahare ea leihlo la hau. Ka mor'a hore sehlopha sa pele sa litšoantšo se nkuoe, dae e bitsoang fluorescein e kenella mothapong. Hangata e entoa kahare ho setsoe. Sesebelisoa se kang k'hamera se nka litšoantšo ha dae e feta methapong ea mali ka morao ho leihlo la hao.

Mokhoa o mocha o bitsoang ultra-widefield fluorescein angiography o ka fana ka tlhaiso-leseling e batsi ka mafu a mang ho feta angiography e tloaelehileng.

O tla hloka motho ya o khannelang hae. Pono ea hau e ka ba lerootho ho fihlela lihora tse 12 kamora tlhahlobo.

U kanna oa bolelloa hore u tlohele ho noa meriana e ka amang litholoana tsa liteko. Bolella mofani oa hau ka ho kula hohle, haholo-holo karabelo ea iodine.

O tlameha ho saena foromo ea tumello e nang le tsebo. O tlameha ho tlosa lilense tsa puisano pele ho tlhahlobo.

Bolella mofani oa litšebeletso haeba u ka ima.

Ha nale e kentsoe, batho ba bang ba utloa bohloko bo fokolang. Ba bang ba ikutloa feela ho hlaba kapa ho hlaba. Kamora moo, ho kanna ha ba le ho tsitsipana.

Ha dae e entsoe, u ka ba le ho nyekeloa ke pelo le maikutlo a futhumetseng 'meleng oa hau. Matšoao ana a fela kapele boholo ba nako.

Dae e tla etsa hore moroto oa hau o be lefifi. E kanna ea ba 'mala oa lamunu ka letsatsi kapa a mabeli kamora tlhahlobo.

Teko ena e etsoa ho bona hore na ho na le phallo ea mali e nepahetseng methapong ea mali likarolong tse peli tse ka morao ho leihlo la hao (retina le choroid).

E ka sebelisoa ho fumana mathata ka leihlong kapa ho tseba hore na kalafo ea mahlo e sebetsa hantle hakae.

Sephetho se tloaelehileng se bolela hore likepe li hlaha ka boholo bo tloaelehileng, ha ho na likepe tse ncha tse sa tloaelehang, ebile ha ho na li-blockages kapa li dutla.

Haeba ho thiba kapa ho dutla ho le teng, litšoantšo li tla etsa 'mapa oa sebaka seo kalafo e ka bang teng.

Boleng bo sa tloaelehang ho angiography ea fluorescein bo ka bakoa ke:

• Mathata a phallo ea mali (circulatory), joalo ka ho thiba methapo kapa methapo
• Kankere
• Lefu la tsoekere kapa retinopathy e 'ngoe
• Khatello ea mali e phahameng
• Ho ruruha kapa edema
• Ho senyeha ha Macular
• Microaneurysms - ho atolosoa ha capillaries ho retina
• Lihlahala
• Ho ruruha ha disc ea optic

Teko e kanna ea etsoa haeba u na le:

• Sehlopha sa Retinal
• Retinitis pigmentosa

Ho na le monyetla o fokolang oa tšoaetso nako le nako ha letlalo le robehile. Hangata, motho o ameha haholo ka dae mme a ka ba le boiphihlelo:

• Ho tsekela kapa ho akheha
• Molomo o omileng kapa salivation e eketsehileng
• Hives
• Ho eketseha ha lebelo la pelo
• Tatso ea tšepe molomong
• Ho nyekeloa le ho hlatsa
• Ho thimola

Liketso tse matla tsa aleji ha li fumanehe hangata.

Liphetho tsa liteko li thata ho hlalosoa ho batho ba nang le lera la mahlo. Mathata a phallo ea mali a bontšitsoeng ho fluorescein angiography a ka fana ka maikutlo a mathata a phallo ea mali likarolong tse ling tsa 'mele.
