Inkcazo: Igama elithi "umboniso wombono" lisetyenziselwa ukuchaza intsimi yombono apho umntu egcina umbono walo ophakathi, kodwa unako ukubonakala kombono wendawo . Umbono ulungele phambili kodwa umbono kumacala awucacile. Kwakhona kuthiwa "yintsimi ye-tubular" ngabagqirha beeliso, umbono weTurkey ufana nokukhangela ityhubhu encinane. Abantu abanombono wethuba badla ixesha elilukhuni ukuhamba ngokukhanyisa, njengokwimidlalo yemafilimu emnyama.
Izizathu zeMboniselo yeTunnel
Imiqathango emininzi ingakhokelela kumbono we-tunnel. Ukulahleka kwegazi kwiindawo ezithile zeengqondo ngamanye amaxesha kungakhokelela ekuboneni umboniso. Umbono weTunnel ungabangelwa yindumbu yokunyanzela kwi-optic nererve. Ezinye izifo zamehlo zingabangela umboniso wethuna. I-Retinitis pigmentosa yisifo esibalulekileyo esiyilungu esingaba neyona nto ingakhokelela kumbono we-tunnel kwaye mhlawumbi ubumfama obuphelele. I-Glaucoma, isifo se-optic nesibindi esabangelwa ngaphezu koxinzelelo lwamehlo eqhelekileyo, sinokubangela.
Nangona i-stroke kunye ne- retinal detachment ingabangela imithombo ebonakalayo engabonakaliyo, imbonakalo ye-tunnel ngokuqhelekileyo ibangelwa yi- glaucoma enamandla kunye ne-retinitis pigmentosa. Ukuxinezeleka kunye nezinye iingxaki zengqondo zingabangela ukuba nombono wombono we-tunnel. Iingxaki zengqondo kunye neengxaki ze-optic ezinjenge- optic neuritis nazo zingabangela intsimi ebonakalayo ebonakalayo.
Ngaba iMboniselo yeTunnel iyingozi?
Naluphina uhlobo lokulahlekelwa kombono okanye ukuphazamiseka kokubonakalayo kunokubangela ukwethusa.
Iziganeko ezinzima kakhulu ngezinye izihlandlo zikhokelela ekuboneni umboniso. Ngokomzekelo, insimu yomboniso yomntu ingahlawuliswa ngexesha lesiganeko sokuhlaselwa kwesifo. Eminye imidlalo ebalulekileyo ingabangela ukuba imeko ibonakale, kunye nemisebenzi ethile efana nabaqhubi beemoto. Ukukhawuleza okuphakamileyo kuye kwabizwa ngokuba yimbangela yombono wethuna.
Ngenxa yokuba umbono ubonakala ungqongqo kakhulu, ukuqala ngokukhawuleza kombono we-tunnel kunokuba yingozi kwaye kufuneka uphathwe njengengxamiseko yonyango.
Nangona kunjalo, xa umbono we-tunnel uqala ngokubhekiselele ekulahlekeni kombono ogqithisileyo ovela kwizifo ezithile zamehlo, ezifana ne-glaucoma, ayithathwa njengongxamiseko lwezonyango. Ugqirha lakho kwamehlo liya kugcina umboniso osondeleyo wombono utshintsha ngelixa unyango.
Ukuphila Ngombono weTunnel
Abantu abanombono wethutho banqamle inkululeko yabo yokuhamba. Ngenxa yokuba umbono uphelelwe ngqo ngqo, umntu uya kufuneka asebenzise ulumkiso xa ehamba egumbini. Asinakuqonda ukuba sisisebenzisa kangakanani umboniso wethu wembonakalo kuze kube yilapho isuswa. Kusenokungenakwenzeka ukufumana ilayisenisi yokuqhuba ngombono we-tunnel, njengoko ukushayela kufuna ukuba ubone yonke into ejikelezile.
Oko Okufanele Uyazi
Ukuhamba ngeenqwelo moya kungakubeka engozini yokuphuhlisa umboniso wombane. Ukubonakaliswa emoyeni okuye kwonakaliswe ngamafutha kunye ne-hydraulic fluids kungenza ukuba imeko ibuye iphuhlise. Iingxaki zengqondo zesikhashana ziqhelekileyo kubantu abagulayo xa behamba ngeenqwelo.
ukuba ngokukhawuleza uhlakulele umbono we-tunnel, khangela unyango ngokukhawuleza. Nangona imeko ingenakukwazi ukuguqulwa, unyango lwangaphambili lunokuthintela ukulahleka kombono.
