Amehlo ethu afana neekhamera zobuchwepheshe obuphezulu. Emva kwale khamera kukho inwebu ebaluleke kakhulu, esiyibiza ngokuba yi-retina. Eli candelo kulapho imiqondiso esiyibonayo ithunyelwa khona ebuchotsheni. Ngoko ke, ukuba unengxaki ngokubona kwakho, kwenziwa uvavanyo olukhethekileyo olubizwa ngokuba yi-Fluorescein Angiography ukuze kubonwe ukuba kukho ingxaki na kwimithambo yegazi emincinci kwi-retina. Nangona igama liyinkimbinkimbi kancinci, masithethe ngento eyenzekayo koku.
Ngamafutshane, yintoni i-Fluorescein Angiography?
Cinga ngemithambo yegazi emincinci engaphakathi kweliso lakho njengeetyhubhu ezibonakalayo. Xa igazi lihamba ngale mibhobho, kunzima ukubona ngaphandle ukuba kukho ukuvaleka, ukuvuza, okanye enye ingxaki.
I-Fluorescein Angiography ibandakanya ukufaka idayi ekhethekileyo emthanjeni osengalweni yakho. Le dayi ibizwa ngokuba yi-fluorescein. Le dayi ihamba emzimbeni wakho ngegazi lakho kwaye ingena nakwimithambo yegazi ekwi-retina yakho. Into ekhethekileyo ngale dayi kukuba yenza imithambo yegazi ibonakale ngokucacileyo. Emva koko, ikhamera ekhethekileyo ithatha imifanekiso eliqela (iifoto) zangaphakathi kweliso lakho. Ngokukodwa, umfanekiso ubonisa idayi ehamba ngemithambo yegazi.
Ngokujonga le mifanekiso, ugqirha wakho wamehlo unokufumanisa naziphi na izithintelo, ukuvuza, ukukhula okungaqhelekanga, okanye omnye umonakalo kwimithambo yegazi.
Lolu vavanyo lufumanisa izifo ezinjani?
Olu vavanyo lubaluleke kakhulu ekuxilongeni izifo ezahlukeneyo ezinxulumene ne-retina yeliso nasekujongeni inkqubela yesifo ngexesha lonyango. Makhe sijonge ezinye zezifo ezinjalo kwitheyibhile engasezantsi.
| Imeko | Kalula nje... |
|---|---|
| Ukuwohloka kwe-macular okunxulumene nobudala | Imeko ebangela ukuba ukubona kudodobale kancinci kancinci kubantu abaneminyaka engaphezu kwama-50 ubudala. |
| Ukudumba embindini we-retina (i-Cystoid macular edema) | Ukudumba kunye nokungaboni kakuhle ngenxa yolwelo oluzalisa inxalenye esembindini we-retina. |
| Ukonakala kwamehlo ngenxa yesifo seswekile (i-Diabetes-related retinopathy) | Isifo seswekile senza buthathaka imithambo yegazi kwi-retina, nto leyo ebangela umonakalo ekuboneni. |
| Umngxuma we-macular | Umbono utshintsha ngenxa yomngxuma omncinci embindini we-retina. |
| I-macular pucker | Umbono uphazamiseka ngenxa yokwakheka kwesakhiwo esifana ne-membrane kwi-retina kunye nokushwabana kwayo. |
| Umhlaza wamehlo (i-Ocular melanoma) | Uhlobo lomhlaza oluvela ngaphakathi kweliso. |
| Ukuqhekeka kwe-retinal | I-retina iyahlukana nezicubu ezixhasayo. |
| I-Retinitis pigmentosa | Iqela lezifo zamehlo ezizuzwe njengelifa ezinokubangela iimeko ezinzima ezifana nokuncipha kokubona ebusuku kunye nokungaboni mbala. |
Ufanele uzilungiselele njani ngaphambi kovavanyo?
Ugqirha wakho uza kukunika imiyalelo efunekayo ngaphambi kolu vavanyo, kodwa lumka ngakumbi ngala manqaku.
- Musa ukuqhuba: Ngeli xesha lovavanyo, kusetyenziswa amaconsi akhethekileyo amehlo ukwandisa imbombo yeliso lakho. Oku kunokubangela ukuba umbono wakho ungacaci ukuya kuthi ga kwiiyure ezili-12. Ngoko ke, qiniseka ukuba uza nomntu oza kuvavanyo naxa ugoduka. Awuyi kukwazi ukuqhuba.
- Xelela ugqirha malunga neyeza:Qiniseka ukuba uxelela ugqirha wakho ngamayeza owasebenzisa rhoqo. Ungacelwa ukuba uyeke ukusebenzisa amayeza athile ngosuku olungaphambi kovavanyo.
- Xelela ugqirha wakho ngazo naziphi na izinto ezibangela ukuba ungabi namdla: Ukuba kukho nantoni na onokuyenza, ingakumbi i-iodine , yazisa ugqirha wakho kwangaphambili.
- Ukuba ukhulelwe: Ukuba ukhulelwe okanye ucinga ukuba ukhulelwe, ngokuqinisekileyo kufuneka uxelele ugqirha wakho.
Kwenzeka ntoni ngexesha lovavanyo?
Olu vavanyo ludla ngokwenziwa eofisini kagqirha wakho. Luvavanyo olukhawulezayo kakhulu, oluthatha ngaphantsi kwemizuzu engama-30.
1. Okokuqala, ugqirha okanye umncedisi uza kubeka amaconsi emehlweni akho. Oku kuya kubangela ukuba umbungu weliso ukhule.
2. Emva koko, uza kuhlala phambi kwekhamera ekhethekileyo. Uza kuyalelwa ukuba ubeke ibunzi nesilevu sakho kuyo kwaye ungashukumi.
3. Ngaphambi kokuba ubhoboze idayisi, thatha imifanekiso emininzi ngekhamera.
4. Okulandelayo, idayi ebizwa ngokuba yi-'fluorescein' iya kufakwa emthanjeni osengalweni yakho.
5. Njengoko idayi ihamba ngemithambo yegazi engaphakathi kweliso, ikhamera ithatha imifanekiso emininzi ngesantya esiphezulu.
Olu vavanyo alunabuhlungu, kodwa ukuba ufumana naluphi na uvakalelo olungathandekiyo, xelela ugqirha wakho.
Yintoni onokuyilindela emva kovavanyo?
Ungagoduka ngaloo mini inye emva kovavanyo, kodwa lumka kwezi zinto kangangeeyure ezimbalwa emva koko.
- Uvelwano ekukhanyeni: Ungaziva ungakhululekanga xa ukukhanya kubetha emehlweni akho. Ke ngoko, kungcono ukunxiba iiglasi zelanga de le meko iphele.
- Umbono ofipheleyo: Njengoko besitshilo ngaphambili, amathontsi amehlo aya kubangela umbono ofipheleyo kangangeeyure ezimbalwa. Yiyo loo nto sicebisa ukuba uze nomntu. Ukuba kunokwenzeka, kungcono uthabathe ikhefu emsebenzini uze uphumle.
Ngaba kukho naziphi na iingozi okanye iziphumo ebezingalindelekanga koku?
I-Fluorescein angiography luvavanyo olukhuselekileyo kakhulu. Nangona kunjalo, njengalo naluphi na uvavanyo lwezonyango, luneziphumo ebezingalindelekanga ezincinci kunye neengozi ezingaqhelekanga.
Iziphumo Eziqhelekileyo Ezingalindelekanga
Ezi zizinto eziqhelekileyo, ungakhathazeki ngale nto.
- Ukutyheli kolusu: Ungabona ukutyheli kancinci kolusu lwakho kangangeeyure ezimbalwa emva kovavanyo.
- Ukutshintsha kombala womchamo: Umchamo wakho unokuba nombala otyheli okanye o-orenji obumnyama kangangeeyure ezingama-24. Le yindlela ekhutshwa ngayo idayi emzimbeni.
- Umbono ofipheleyo:Umbono wakho usenokuba luzizi kancinci kangangemizuzu embalwa.
- Ukutsha kwindawo yokuhlatywa kwenaliti: Ukuba idayi ivuza kancinci ngexesha lokuhlatywa kwenaliti, ungaziva ukutshisa eluswini lwakho. Oku kuya kuphela emva kwemizuzu embalwa.
Ezinye iimeko ezinokwenzeka kwabanye abantu
Ezi zinto azenzeki kubo bonke abantu, kodwa abanye abantu basenokuziva ezi zinto.
- Ndiziva ndinesizungu.

Iimpendulo ze-Allergic
Oku kunqabile kakhulu , kodwa kubalulekile ukukwazi. Abanye abantu banokuba ne-allergy kule dayi. Kwiimeko ezinjalo, unokufumana iimpendulo zesikhumba ezifana nokurhawuzelelwa okanye ukurhawuzelelwa.
Ngaba kukho amaxesha apho kufuneka uye kwiYunithi yoNyango oluNgxamisekileyo (i-ETU)?
Ukuba ufumanisa iimpawu zokunganyamezelani komzimba (ezifana nokurhawuzelela kolusu, ukurhawuzelela) emva kovavanyo, tsalela umnxeba ugqirha wakho ngoko nangoko.
Amaxesha amaninzi, abanye abantu banokufumana i-allergy enzima (i-anaphylaxis). Oku kunokuba yingozi ebomini. Ukuba ufumana naziphi na iimpawu ezinjengobunzima bokuphefumla, ukuqina kwesifuba, okanye ubunzima bokuthetha, yiya kwicandelo elikufutshane lesibhedlele esingxamisekileyo (ETU) ngaphandle kokulibazisa.
Singazazi nini iziphumo?
Ugqirha wakho wamehlo uza kuhlalutya imifanekiso evela kuvavanyo aze akuchazele iziphumo kwiintsuku ezimbalwa. Ukuba imifanekiso ibonisa naziphi na izithintelo okanye ukuvuza kwimithambo yegazi, kusenokuba ngenxa yemeko ebizwa ngokuba yi-diabetes-related retinopathy okanye i-macular degeneration. Ukuba kuyimfuneko, ugqirha wakho unokuyalela ezinye iimvavanyo.
Umyalezo Wokuya Ekhaya
- I-Fluorescein Angiography yindlela ekhuselekileyo ehlola imithambo yegazi kwi-retina engaphakathi kweliso lakho.
- Olu vavanyo alubuhlungu, kodwa umbono wakho usenokuba lufiphale kangangeeyure ezimbalwa emva kovavanyo.
- Qiniseka ukuba uzisa umntu oza kukusa kuvavanyo uze ugoduke. Awuyi kukwazi ukuqhuba.
- Kuqhelekile ukuba nolusu olumthubi nomchamo omnyama kangangeentsuku emva kovavanyo. Musa ukukhathazeka ngaloo nto.
- Iimpendulo eziqatha ze-allergy azixhaphakanga, kodwa ukuba ufumana ubunzima bokuphefumla, yiya kwiSebe leNgxamiseko (ETU) elikufutshane ngoko nangoko.
- Kubaluleke kakhulu ukwazisa ugqirha ngazo zonke ii-allergies zakho kunye namayeza owasebenzisayo ngaphambi kovavanyo.
