Amehlo ethu afana namakhamera obuchwepheshe obuphezulu. Ngemuva kwale khamera kukhona ulwelwesi olubaluleke kakhulu, esilubiza ngokuthi i-retina. Le ngxenye yilapho izimpawu esizibonayo zithunyelwa khona ebuchosheni. Ngakho-ke, uma unenkinga ngokubona kwakho, kwenziwa ukuhlolwa okukhethekile okubizwa ngokuthi i-Fluorescein Angiography ukuze kubonakale ukuthi kukhona yini inkinga ngemithambo yegazi emincane ku-retina. Nakuba igama liyinkimbinkimbi kancane, ake sixoxe ngalokho okwenzekayo kulokhu.
Kalula nje, iyini i-Fluorescein Angiography?
Cabanga ngemithambo yegazi emincane engaphakathi kweso lakho njengamapayipi abonakalayo. Uma igazi ligeleza kula mapayipi, kunzima ukubona ngaphandle ukuthi kukhona yini ukuvaleka, ukuvuza, noma enye inkinga.
I-Fluorescein Angiography ihilela ukufaka idayi ekhethekile emthanjeni osengalweni yakho. Le dayi ibizwa ngokuthi i-fluorescein. Le dayi ihamba emzimbeni wakho wonke negazi lakho futhi ingena nasemithanjeni yegazi e-retina yakho. Into ekhethekile ngale dayi ukuthi yenza imithambo yegazi ivele ngokucacile. Ngemuva kwalokho, ikhamera ekhethekile ithatha izithombe eziningana (izithombe) zengaphakathi leso lakho. Ngokukhethekile, isithombe sibonisa idayi ihamba emithanjeni yegazi.
Ngokubheka lezi zithombe, udokotela wakho wamehlo angakwazi ukubona noma yikuphi ukuvinjelwa, ukuvuza, ukukhula okungavamile, noma omunye umonakalo emithanjeni yegazi.
Lolu hlolo luthola ziphi izifo?
Lokhu kuhlolwa kubaluleke kakhulu ekuxilongeni izifo ezahlukahlukene ezihlobene ne-retina yeso kanye nokuqapha inqubekela phambili yesifo ngesikhathi sokwelashwa. Ake sibheke ezinye zezifo ezinjalo kuthebula elingezansi.
| Isimo | Kalula nje... |
|---|---|
| Ukuwohloka kwe-macular okuhlobene nobudala | Isimo esibangela ukuthi ukubona kuwohloke kancane kancane kubantu abaneminyaka engaphezu kwengu-50. |
| Ukuvuvukala enkabeni ye-retina (i-Cystoid macular edema) | Ukuvuvukala kanye nokungaboni kahle ngenxa yoketshezi olugcwalisa ingxenye ephakathi ye-retina. |
| Ukulimala kwamehlo okubangelwa isifo sikashukela (i-retinopathy ehlobene nesifo sikashukela) | Isifo sikashukela senza buthaka imithambo yegazi ku-retina, okubangela ukulimala kokubona. |
| Umgodi we-macular | Ukushintsha kombono ngenxa yembobo encane enkabeni ye-retina. |
| I-macular pucker | Ukubona kuyaphazamiseka ngenxa yokwakheka kwesakhiwo esifana nolwelwesi ku-retina kanye nokushwabana kwayo. |
| Umdlavuza wamehlo (i-Ocular melanoma) | Uhlobo lomdlavuza oluvela ngaphakathi kweso. |
| Ukuhlukaniswa kwe-retinal | I-retina iyahlukana nezicubu eziyisekelayo. |
| i-retinitis pigmentosa | Iqembu lezifo zamehlo ezizuzwe njengefa ezingabangela izimo ezinzima njengokuncipha kokubona ebusuku kanye nokungaboni kahle kombala. |
Kufanele uzilungiselele kanjani ngaphambi kokuhlolwa?
Udokotela wakho uzokunikeza imiyalelo edingekayo ngaphambi kwalolu vivinyo, kodwa qaphela kakhulu ngala maphuzu.
- Ungashayeli: Phakathi nalolu vivinyo, amaconsi amehlo akhethekile asetshenziswa ukwandisa inhlamvu yeso lakho. Lokhu kungabangela ukuthi umbono wakho ufiphale kuze kube amahora angu-12. Ngakho-ke, qiniseka ukuthi unomuntu ohamba nawe uma uza esivivinyweni nalapho uya ekhaya. Ngeke ukwazi ukushayela.
- Tshela udokotela ngomuthi:Qiniseka ukuthi utshela udokotela wakho nganoma yimiphi imithi ovame ukuyithatha. Ungase ucelwe ukuthi uyeke ukuthatha imithi ethile ngosuku olungaphambi kokuhlolwa.
- Tshela udokotela wakho nganoma yikuphi ukungezwani komzimba: Uma kukhona ukungezwani komzimba nanoma yini, ikakhulukazi i-iodine , yazisa udokotela wakho kusenesikhathi.
- Uma ukhulelwe: Uma ukhulelwe noma ucabanga ukuthi kungenzeka ukuthi ukhulelwe, kufanele utshele udokotela wakho nakanjani.
Kwenzekani ngesikhathi sokuhlolwa?
Lokhu kuhlolwa kuvame ukwenziwa ehhovisi likadokotela wakho. Kuwukuhlolwa okusheshayo kakhulu, kuthatha imizuzu engaphansi kwengu-30.
1. Okokuqala, udokotela noma umsizi uzofaka amaconsi emehlweni akho. Lokhu kuzokwenza ukuthi inhlamvu yeso ikhule.
2. Ngemuva kwalokho, uzohlala phambi kwekhamera ekhethekile. Uzoyalwa ukuba ubeke ibunzi lakho nesilevu sakho kuyo futhi unganyakazi.
3. Ngaphambi kokubhoboza idayisi, thatha izithombe eziningana ngekhamera.
4. Okulandelayo, idayi ebizwa ngokuthi i-'fluorescein' izofakwa emthanjeni osengalweni yakho.
5. Njengoba udayi uhamba ngemithambo yegazi engaphakathi kweso, ikhamera ithatha izithombe eziningi ngesivinini esikhulu.
Lokhu kuhlolwa ngokuvamile akubuhlungu, kodwa uma uzwa ukungakhululeki, tshela udokotela wakho.
Yini ongayilindela ngemva kokuhlolwa?
Ungaya ekhaya ngalolo suku ngemva kokuhlolwa, kodwa qaphela lezi zinto amahora ambalwa ngemva kwalokho.
- Ukuzwela ukukhanya: Ungase uzizwe ungakhululekile kancane lapho ukukhanya kushaya emehlweni akho. Ngakho-ke, kungcono ukugqoka izibuko zelanga kuze kube yilapho lesi simo siphela.
- Ukubona okufiphele: Njengoba sishilo ekuqaleni, amaconsi amehlo azobangela ukubona okufiphele amahora ambalwa. Yingakho sincoma ukuthi uze nomuntu. Uma kungenzeka, kungcono ukuthatha usuku lokuphumula emsebenzini uphumule.
Ingabe kukhona izingozi noma imiphumela emibi kulokhu?
I-fluorescein angiography iyisivivinyo esiphephile kakhulu. Kodwa-ke, njenganoma yikuphi ukuhlolwa kwezokwelapha, inemiphumela emibi emincane kanye nezingozi ezingavamile kakhulu.
Imiphumela Emibi Evamile
Lezi yizinto ezivamile, ungakhathazeki ngalokhu.
- Ukuphuzi kwesikhumba: Ungase uqaphele ukuphuzi okuncane kwesikhumba sakho amahora ambalwa ngemva kokuhlolwa.
- Ukushintsha kombala womchamo: Umchamo wakho ungase ube nombala ophuzi noma o-orenji obumnyama cishe amahora angama-24. Lena yindlela udayi okhishwa ngayo emzimbeni.
- Umbono ofiphele:Umbono wakho ungase ungabonakali kahle imizuzu embalwa.
- Umuzwa wokusha endaweni yokujova: Uma udayi uvuza kancane ngesikhathi sokujova, ungase uzwe umuzwa wokusha esikhumbeni sakho. Lokhu kuzophela ngemizuzu embalwa.
Ezinye izimo ezingase zenzeke kwabanye abantu
Lezi zinto azenzeki kuwo wonke umuntu, kodwa abanye abantu bangase bazizwe lezi zinto.
- Ukuzizwa unesizungu.
- Umlomo owomile.
- Ukwanda kwesilinganiso senhliziyo.
- Ukunambitheka kwensimbi emlonyeni.
- Ukucanuzela noma ukuhlanza.
- Ukuthimula.
Ukusabela Kokungezwani Nomzimba
Lokhu akuvamile kakhulu , kodwa kubalulekile ukukuqaphela. Abanye abantu bangaba ne-allergy kule dayi. Ezimweni ezinjalo, ungase ube nokusabela kwesikhumba okufana nokuqunjelwa noma ukulunywa.
Zikhona yini izikhathi lapho kudingeka uye e-Emergency Treatment Unit (ETU)?
Uma uba nezimpawu zokungezwani komzimba (njengokuqubuka kwesikhumba, ukulunywa) ngemva kokuhlolwa, shayela udokotela wakho ngokushesha.
Akuvamile kakhulu, abanye abantu bangase babe nokusabela okukhulu kokungezwani komzimba (i-anaphylaxis). Lokhu kungaba yingozi empilweni. Uma uhlangabezana nanoma yiziphi izimpawu ezifana nobunzima bokuphefumula, ukuqina kwesifuba, noma ubunzima bokukhuluma, hamba uye emnyangweni wezimo eziphuthumayo esibhedlela esiseduze (i-ETU) ngokushesha.
Singazi nini imiphumela?
Udokotela wakho wamehlo uzohlaziya izithombe ezivela esivivinyweni bese ekuchazela imiphumela zingakapheli izinsuku ezimbalwa. Uma izithombe zibonisa noma yikuphi ukuvinjelwa noma ukuvuza emithanjeni yegazi, kungaba ngenxa yesimo esibizwa ngokuthi i-diabetes-related retinopathy noma i-macular degeneration. Uma kudingeka, udokotela wakho angase acele ukuhlolwa okwengeziwe.
Umlayezo Wokuya Nawe Ekhaya
- I-Fluorescein Angiography inqubo ephephile ehlola imithambo yegazi ku-retina engaphakathi kweso lakho.
- Lokhu kuhlolwa akubuhlungu, kodwa umbono wakho ungase ungabonakali amahora ambalwa ngemva kokuhlolwa.
- Qiniseka ukuthi uletha umuntu ozokuthatha ayokuhlola futhi akuyise ekhaya. Ngeke ukwazi ukushayela.
- Kujwayelekile ukuba nesikhumba esiphuzi nomchamo omnyama cishe usuku lonke ngemva kokuhlolwa. Ungakhathazeki ngalokho.
- Ukusabela okukhulu kokungezwani komzimba akuvamile, kodwa uma ubhekene nobunzima bokuphefumula, hamba ngokushesha eMnyangweni Wezimo Eziphuthumayo (ETU).
- Kubaluleke kakhulu ukwazisa udokotela ngazo zonke izinhlobo zokungezwani komzimba kwakho kanye nemithi oyiphuzayo ngaphambi kokuhlolwa.
