Ngaba ukhe waqaphela ngequbuliso ukuba umbono wakho kwelinye iliso awubonakali kakuhle? Okanye uziva ngathi izinto ezincinci ezimnyama ziyadada phambi kweliso lakho? Kuqhelekile ukuba uzive usoyika kancinci xa kwenzeka into efana nale. Ixesha elininzi, oku kunokubangelwa kukuvaleka komthambo omncinci wegazi ngaphakathi kweliso lakho. Ngokwezonyango, oku sikubiza ngokuba yiRetinal Vein Occlusion, okanye iRVO ngamafutshane. Makhe sithethe ngale nto ngokulula namhlanje.
Ngamafutshane, yintoni i-retinal vein occlusion (RVO)?
Cinga ngeliso lakho njengekhamera. Inxalenye yeliso ebizwa ngokuba yi-retina ifana nefilimu engasemva kwekhamera. Kulapho ukukhanya kwezinto esizibonayo kuguqulwa khona kube yimifanekiso. Ngoko ke, ukuze le retina isebenze kakuhle, kufuneka igazi lihlale lilungile. Oko kuthetha ukuba kukho imithambo yegazi ebuyisela igazi kunye nemithambo yegazi esetyenzisiweyo.
Ngoku khawucinge ukuba ngesizathu esithile, umthambo othwala elo gazi ubuyela umva, umthambo, uvaleka kancinci okanye uvaleke. Kanye njengokuba umbhobho wamanzi uvaleka, igazi alikwazi ukuhamba kuwo. Emva koko, igazi liyabuyela umva, lonyusa uxinzelelo ngaphakathi kwi-retina kwaye libangele ukuba idumbe. Oku sikubiza ngokuba yi -Retinal Vein Occlusion (RVO) . Le yimeko ekufuneka inyangwe ngokukhawuleza, okanye inokubangela ukulahleka kokubona okungapheliyo.
Kukho iintlobo ezimbini eziphambili zee-RVO.
Sizahlulahlula ii-RVO zibe ziintlobo ezimbini kuxhomekeke ekubeni oku kuthinteleka kwenzeka phi.
| Uhlobo lwe-RVO | Kalula nje... |
|---|---|
| Ukuvalelwa kwemithambo ye-Central Retinal Vein (CRVO) | Oku kukuvaleka komthambo oyintloko kwi-retina. Kufana nombhobho omkhulu wamanzi ovalwayo. Oku kunokuchaphazela i-retina yonke. |
| Ukuvalelwa kwemithambo ye-Retinal yesebe (i-BRVO) | Olu luvalelo lomthambo omncinci wesebe osuka kumthambo oyintloko. Olu lolona hlobo luqhelekileyo. Kwimeko enjalo, yinxalenye enye kuphela ye-retina echaphazelekayo. |
Ziziphi iimpawu onokuzifumana ngexesha le-RVO?
Iimpawu ze-RVO zihlala zichaphazela iliso elinye kuphela. Zinokuqala ngequbuliso okanye zikhule kancinci kancinci kangangeeyure okanye iintsuku.
- Ukubona okufipheleyo okanye ukulahleka kombono: Olu lolona phawu luphambili noluqhelekileyo.
- IiFloaters: Ukubona amachaphaza amnyama okanye imigca edada phambi kwamehlo.
- Ukuva intlungu okanye uxinzelelo ngaphakathi kweliso: Oku kubonakala kwiimeko eziqatha ngakumbi.
Into ebalulekileyo kukuba, ngamanye amaxesha le meko inokwenzeka ngaphandle kwempawu. Ugqirha wakho angayifumana ngengozi xa uye kuvavanyo lwamehlo oluqhelekileyo. Yiyo loo nto kubalulekile ukuba uhlolwe amehlo akho rhoqo.
Kutheni umthambo ubhajwa ngaphakathi kweliso ngolu hlobo?
Kunzima kakhulu ukukhomba isizathu esinye soku, kodwa kukho izinto ezininzi eziphambili ezibandakanyekayo.
Ngamafutshane, kukho iindawo apho umthambo kunye nomthambo kwi-retina zidibana khona. Njengoko sikhula, okanye ngenxa yokuba izinto ezifana ne-cholesterol ziyanda, iindonga zemithambo ziya ziqina kancinci. Oku sikubiza ngokuba yi-atherosclerosis . Umthambo oqina ngolu hlobo uqala ukucinezela umthambo othambileyo ongaphantsi kwawo. Kufana nombhobho wamanzi otyumkileyo xa kubekwa into enzima phezu kwawo. Olu xinzelelo lunokuthintela ukuhamba kwegazi ngaphakathi komthambo, kwaye ihlwili legazi linokwenza kwaye livale umthambo ngokupheleleyo.
Ukongeza, ezinye iimeko zonyango ziyandisa umngcipheko wokuba ne-RVO.
Izinto ezonyusa umngcipheko we-RVO
| Into enobungozi | Inkcazo |
|---|---|
| Ubudala | Abantu abangaphezu kweminyaka engama-40 ubudala basengozini enkulu. Ixhaphake kakhulu kubantu abaneminyaka engama-50-60 ubudala. |
| Igazi elonyukayo | Le yingxaki enkulu kwi-RVO. |
| Isifo seswekile | Isifo seswekile singonakalisa imithambo yegazi ethambileyo esweni. |
| I-Glaucoma | Le meko, eyonyusa uxinzelelo lwamehlo, nayo iyingozi. |
| I-Cholesterol ephezulu kunye ne-Atherosclerosis | Ukuvaleka kungenzeka ngenxa yokuqina nokuncitshiswa kwemithambo yegazi. |
Zeziphi iingxaki ezinokwenzeka ukuba azinyangwa?
Ukuba i-RVO ayinyangwa ngokukhawuleza, inokubangela umonakalo omkhulu emehlweni.
- I-Cystoid Macular Edema: I-macula yeyona ndawo iphambili kwi-retina esinika umbono ocacileyo nobukhali. Xa umthambo wegazi uvalekile, unokuzaliswa lulwelo kwaye udumbe. Oku kunokubangela ukungaboni kakuhle okukhulu.
- Ukuvuselelwa kwegazi: Xa ukuhamba kwegazi ngaphakathi kweliso kuphazamiseka , umzimba uzama ukuvala loo ngxaki ngokwenza imithambo yegazi emitsha. Nangona kunjalo, le mithambo yegazi mitsha ibuthathaka kakhulu kwaye ineendonga ezincinci. Ezi zinokuqhuma lula kwaye zibangele ukopha ngaphakathi kweliso (i-vitreous hemorrhage).
- Uxinzelelo oluphezulu elisweni (Neovascular Glaucoma): Le mithambo yegazi emitsha nebuthathaka ivala iindawo ezilawula ukuhamba kolwelo ngaphakathi kweliso. Oku kunokubangela uxinzelelo oluphezulu kakhulu ngaphakathi kweliso, lonakalisa umthambo wokubona kwaye kubangele ukulahlekelwa ngokupheleleyo kombono.
- Ukuqhekeka kweRetina: Le yimeko engxamisekileyo. I-retina inokuphuma eludongeni lweliso ngenxa yokutsalwa kwemithambo yegazi emitsha.
Ugqirha uyixilonga aze ayinyange njani le nto?
Ukuba ufumana ezi mpawu, kuya kufuneka ubone ingcali yokhathalelo lwamehlo ngokukhawuleza. Iya kuhlola amehlo akho ngononophelo.
Uxilongo
Ugqirha uza kubeka amaconsi esweni lakho ukuze avule i-pupil aze ahlole ingaphakathi leliso lakho nge-microscope ekhethekileyo. Ukongeza, kunokwenziwa olu vavanyo lulandelayo:
- Iskeni se-Optical Coherence Tomography (OCT): Oku kunokulinganisa ubukhulu be-retina kwaye kuchonge ngokuchanekileyo ukuba i-macula idumbile na.
- I-Fluorescein Angiography: Idayi ekhethekileyo ifakwa kumthambo osengalweni yakho kwaye imifanekiso ithathwa njengoko ihamba ngemithambo yegazi engaphakathi kweliso lakho. Oku kungabonisa apho umthambo uvalekile khona kunye nokuba umonakalo wenzeke kangakanani.
Iindlela zonyango
Ukuza kuthi ga ngoku, akukho ndlela ikhuselekileyo yokuvula kwakhona umthambo ovalekileyo. Nangona kunjalo, kukho unyango oluninzi olusebenzayo lokulawula umonakalo kunye neengxaki ezibangelwa kukuvaleka . Iinjongo eziphambili zezi zonyango zezi:
- Phucula umbono wakho okanye uyeke ukuba ube mbi ngakumbi.
- Unyango lweengxaki eziye zavela.
- Ukulawula izinto ezinobungozi (ezifana noxinzelelo lwegazi nesifo seswekile) ezibangela i-RVO.
Nazi ezinye zeendlela eziphambili zonyango:
1. Iinaliti ze-Anti-VEGF: Olu lolona nyango lokuqala lusetyenziswa kakhulu. Kukho ikhemikhali (i-VEGF) ebangela ukudumba kunye nokwenziwa kwemithambo yegazi emitsha nebuthathaka ngaphakathi kweliso. Le naliti isebenza ngokuthintela loo khemikhali. Inaliti inikwa emva kokuba iliso liphelelwe ngamandla ngamaconsi eliso. Ngokuxhomekeke kwimeko yakho, unokufuna ukufumana ezi naliti nyanga nganye okanye ngamaxesha athile.
2. Iinaliti zeSteroid: Ezi naliti zikwasetyenziselwa ukunciphisa ukudumba. Nangona kunjalo, zinokunyusa uxinzelelo lwamehlo kwabanye abantu, ngoko ke zinikwa kuphela njengokhetho lwesibini ukuba iinaliti ze-anti-VEGF azincedi.
3. Unyango lweLaser (iPanretinal Photocoagulation - PRP): Olu nyango lweLaser lusetyenziselwa ukunqanda ukwakheka kwemithambo yegazi engafunekiyo nebuthathaka.
4. Utyando lweVitrectomy: Ukuba kukho ukopha okuninzi ngaphakathi kweliso, olu tyando lwenziwa ukuze kususwe kwaye kucocwe inxalenye yeliso efana nejeli egcwele igazi.
Okubaluleke kakhulu, ugqirha wakho wamehlo uza kusebenzisana nogqirha wakho wosapho (PCP) ukuze akunike amayeza okulawula iimeko ezifana noxinzelelo lwegazi oluphezulu, isifo seswekile kunye ne-cholesterol.
Ngekamva kunye noko sinokukwenza
Indlela oza kujonga ngayo i-RVO ixhomekeke kwizinto ezininzi. Abanye abantu baphelelwa yimbono ngokusisigxina, ngelixa abanye bebona umbono wabo uphucuka kancinci kancinci ngokuhamba kwexesha ngonyango. Ugqirha wakho wamehlo unokuchaza imeko yakho ngcono.
