Umxinzelelo ophezulu, kwimithambo yethu yegazi kunye nakwamehlo ethu, akubi kwimpilo yethu. Kwaphela iminyaka, xa oogqirha bezilwanyana bethetha ngokuba ne-glaucoma, izigulane zabo zazihlala zibuza, "Ngaba ukunyanga kwengcinezelo yegazi kubangele ukunyamezela kwelanga kunye ne-glaucoma?"
Nangona ikhonkco yayisoloko inokucingwa ukuba kungenzeka, oogqirha babecinga ukuba ukucinezelwa kwegazi akuzange kusho ukuba ukunyamezela kwamehlo kunye ne-glaucoma ekugqibeleni ziza kukhula.
Nangona igama elithi "uxinzelelo" libandakanyeka kuzo zombini iimeko, ukuphuhliswa kwengcinezelo ephezulu yegazi kuhluke ngokupheleleyo ekuphuhliseni ukunyamezela kwamehlo. Nangona kunjalo, uphando olutsha lubonisa ukuba ukunyuswa kwengcinezelo yegazi kunokwandisa umngcipheko wokuphuhlisa i-glaucoma.
Yintoni i-Glaucoma?
I-Glaucoma ibhekisela kwiqela lezifo ezidala umonakalo kwiimbono ze-optic. Equkethe ngaphezu kweyimizi yezigulane, i-nertic optic idibanisa iliso kwingqondo. Le ntsho ebalulekileyo ijongene nokuthwala imifanekiso ebuchosheni. Iimbono ze-optic ze-nerve zenza inxalenye ye-retina enika amehlo. Uluhlu lwamafayibha enobungozi lungonakaliswa xa uxinzelelo kwiso (uxinzelelo lwe-intraocular) luba lukhulu kakhulu. Ngexesha elide, uxinzelelo oluphezulu lubangela ukuba i-nerve fibers ife, okubangelwa kwimibono eyancipha. Ukulahleka kombono kunye nokungaboni kakuhle kuya kubangela ukuba i-glaucoma ishiywe ingaphathwa. Abaphandi banomuvo wokuthi ezinye iindidi ze-glaucoma zingabangela ukungahambi kakuhle kwegazi kwi-nertic optic.
Utyinzelelo lwe-Hypertension kunye neGesi yeMpahla
Uxinzelelo lwegazi oluphezulu, olubizwa ngokuba ngumfutho wegazi ophezulu, lunokubangela ukuba iinqwelo zethu zegazi eziqhelekileyo zizinze. Xa imithwalo yegazi iyanzima, ibangela ukuba uxinzelelo lwegazi lwandise, oluvakalayo ukukhawuleza i-atherosclerosis (ukwakheka kwe-plaque kwiindonga zeetriyri).
I-atherosclerosis ivame ukukhokelela kwisitya segazi kunye nokuvelisa iintliziyo, izibetho kunye nezinye iingxaki ezinzulu. Ukongezelela, imithambo yegazi ingaba buthathaka ngaphezu kwexesha ukusuka kwingcinezelo ephezulu yegazi, kwaye indawo ezinobuthakathaka ziyakhula. Ezi ndawo ezinobuthakathaka emithanjeni yegazi ziqokelela igazi kwaye ziba zi-poch-outs ezibizwa nge-aneurysms. I-Aneurysms iyakhupha kwaye ivuza igazi, idale umonakalo kwizitho.
Uxinzelelo lwegazi oluphezulu kunye neGlaucoma
Kwaye kwakucingwa ukuba ingcinezelo encinci yegazi ingaba yinto enhle ye- glaucoma . Ukuba noxinzelelo oluphezulu lwegazi luqinisekisa ukuba kukho ukuhamba kakuhle kwegazi kumathambo omzimba welihlo. Nangona kunjalo, ngokwezifundo ezintsha , ukunyuswa kwengcinezelo yexesha elide kwandisa umngcipheko omkhulu wokuphuhlisa i-glaucoma.
Olunye uphando lubonise ukuba ukunyanga kwengcinezelo yegazi kungabangela umngcipheko we-glaucoma. Nangona kunjalo, asiyiqondi ngokwenene isizathu. Abaphandi baye bafumanisa ukuba abantu abaselula abanomfutho wegazi ophakanyisiweyo banokukhuselwa kunye ne-glaucoma kodwa uxinzelelo lwegazi oluphezulu kubantu abadala liyingozi enkulu. Abaphandi banomuvo wokuthi nayiphi na inzuzo yokuba nomfutho wegazi ophezulu unxamnye ngenxa yokuba uxinzelelo oluphezulu lwegazi lubangela umonakalo kwimithambo yegazi ngokuhamba kwesikhathi.
Izifundo zenziwe kwizilwanyana ezibonisa ukuba uxinzelelo lwegazi oluphakamileyo ixesha elide, njengeeveki ezine, alinakukhusela okufanayo kunye noxinzelelo lwamehlo olwenyukayo njengokunyuka kweyure elilodwa.
Oku kuthetha ukuba ukunyuka kwengcinezelo yegazi ngexesha elide kuya kuphazamisa ukukhanya kwamehlo ekujonganeni okanye ukujamelana nokunyamezela kwamehlo.
Oku kuqonda kuya kunceda oogqirha bachonge abantu abasengozini yokuphuhlisa i-glaucoma. Kwakhona kubonisa ukukhanya kwizifundo ezinokuthi zenzeke ezinokuncedisa oogqirha ekuphatheni izigulane ezinama-glaucoma kunye negazi.
