Lamabutho ngwengwzi: izimpawu, izimbangela, ukwelashwa

lamabutho ngwengwzi - isifo esiyingozi kwezitho mbono. Phakathi ukuthuthukiswa kwalesi sifo uyashiywa retina we choroid. Okwamanje, lamabutho retina iyona olunzima ngokuya izimo zokucabanga okubangelwa isifo nokuhlinzwa. Eminyakeni eyishumi edlule sesibone liyanda lokhu nosology. Minyaka yonke, lamabutho ngwengwzi kwenzeka oyedwa 10,000 abantu futhi yezimbangela yobumpumputhe nokukhubazeka. Phakathi wamadoda waba kungathi 70% ukuphathwa yilesi sifo kukhona abantu abaseminyakeni yokusebenza.

Isizathu esikhulu lamabutho ngwengwzi kuba phambi igebe-retina, lapho, ngaphansi kwe-retina uqala ukungena uketshezi Vitreous, kanjalo otslaivaya ivuthele choroid. Nakho kuyisici esibangela esimweni ukuthuthukisa isifo lezi zinkinga kwegazi, okuholela okuvela izinqubo esiwohlozayo, futhi ngenxa yalokho, ukuhlukumeza ubudlelwano phakathi umzimba Vitreous futhi retina.

lamabutho ngwengwzi kuyashaqisa, esiwohlozayo, futhi idiopathic. Izimpawu ezisemqoka amehlo ombozwe flash anombala ocwazimulayo phambi kwamehlo ami njengombani uvela. Ukubukeka lezi nokuqubuka alichaza "nekwendlala" le Vitreous ukuze retina, ngesikhathi esifanayo nje leyo ndawo ilahlekelwa uketshezi retina uqala "iqhubu" kuso. Izikhalazo mayelana "kwesihenqo" noma umgubuzelo phambi kwamehlo athiya obona kahle kungasho ekuqaleni inqubo lamabutho ngwengwzi. Ephambi kwezinduna lezi zimpawu kuyinto esiphuthumayo ukubona ophthalmologist Uchwepheshe luhlolo ngwengwzi phambi Isimo saba bucayi. Akunakusetshenziswa akufanele bazame zelaphe wena noma ukuphi ukuwa noma imijovo, okuwukuphela kwendlela lapho iphathwa lamabutho ngwengwzi - eyohlinzwa Injongo ogama main ukuhlonza ekhona izinyembezi ngwengwzi nokuqeda yayo.

Wenzeka lamabutho ngwengwzi kungaba ngasiphi yobudala, kodwa ezimweni eziningi, lesi sifo kwenzeka kubantu ubudala abavuthiwe engu-25 kuya ku-50 abanokuhlangenwe ukubona eduze (myopia), ngezinga eliphezulu, kanye nasebekhulile ukuhlinzwa ubhekene ngoba cataract ukususwa. The main engcupheni lesi sifo yilezi: a myopia eqinile, ezahlukene ukulimala kwamehlo, ufuzo.

Indlela eyinhloko kwelashwa ukuhlinzwa, okuyisigaba sokuqala okuphumelela ukuhambisana yayo kanye khona yesikhathi eside lamabutho ngwengwzi kuholela neuronal yokufa kwamangqamuzana engokwemvelo kanye izinguquko ezingenakuhlehliswa kwe-retina.

The njalo kunazo wasebenzisa izindlela alulame bathinteka-retina zihlanganisa:

1. sclerosing indlela - ku olwelwesini ucezu iso elise futhi unamathisele gum abicah isipanji noma plastic nokunwebeka, okuyinto evimbela ukwakheka foci entsha delamination, ekunciphiseni ingcindezi kuyi-retina, futhi isekela izingqimba ngwengwzi.
2. Indlela retinopexy womoya - esweni injected emoyeni bubble, okuyinto uthuthe esizeni delamination nemabhuloki ke, kanjalo uvimbele ukudala ezinye ketshezi buthelela ngaphezulu ngaphansi kwe-retina.

Ngezinye izikhathi ukuze kuzuzwe snuggling ephelele lamabutho ngwengwzi kuyadingeka ukuze usebenze izikhathi eziningana. Esimeni lapho lamabutho ayizange wathinta endaweni macular, izibikezelo for nokuvulwa ngempela ukuthi ayemakhulu amathemba ababenawo, kodwa ngenye indlela umbono engaphelele uyohlala phakade. Kobukhulu yokuphambana kuzoncika Isivinini kwegazi bezokwelapha abanekhono.

ukwelashwa prophylactic sikhala abuthakathaka futhi izimbobo abangazange okwamanje kwaholela ekubeni lamabutho ngwengwzi: cryotherapy kanye laser photocoagulation isb ithonya ezishisayo wukushisa noma ezibandayo, ukuvuvukala iqala lapho nokunamathisela ngomthofu senzeka futhi retina choroid.
