Isifo esibi - yoma-optic

Indoda ngempela isidalwa esiyingqayizivele. Nsuku zonke emehlweni ethu iphathwa okuningi kwezinto esizibonayo. Kasazi ukuthi imisebenzi eziyinkimbinkimbi zenzeke, ukuze umuntu abone isithombe esicacile ngaye. Ngenxa pulses ividiyo zidlule emsipheni optic, thina zibukeke ukubona imvelo.

Nokho, zikhona izimo lapho ezinye izindawo ingahambeki. Lokhu yoma ka emsipheni optic. Ngeshwa, lesi sifo ngokuya kuthinta abantu abasha. Cabanga nje ukuthi kungaba inhlekelele lesi sifo aligcwali wamandla namandla zabantu. Ezimweni eziningi, le yoma we emsipheni optic ephelezelwa befa off imicu zayo. Kuze kube muva nje, cishe konke lokhu inhlobo yesifo kubangela ubumpumputhe esinqunyiwe kanye akasabeli ukwelashwa. Odokotela babekholelwa ukuthi nerve izicubu is awabuyiswanga, nezindawo zayo atrophied silahleka unomphela. Manje, bamehlo kakhulu basho lokhu okulandelayo: uma umuntu angakwazi imicu yezinzwa ingxenye, umbono kungenziwa zibuyiswe.

Kuye eziningi izimo, kunezinhlobo eziningi zalesi sifo. Kukhona zamabanga aphansi naphezulu optic yoma. Esimweni sokuqala, lesi sifo singumbulali uhlamvu ngabanye, futhi okwesibili, isifo esibangelwa nezinye izinqubo ukuvuvukala. Kuye ukonakala kwazo emsipheni optic ukuhlukanisa phakathi yoma ngokwengxenye futhi ephelele. Inkambo sifo libabiza isifo bunjwa enenqubekela phambili futhi esinqunyiwe.

Uma sikhuluma yoma sezizathu, angase ezahlukene. Cabanga ayinhloko: izifo iso futhi imithambo yegazi, i-glaucoma owaziwa, imiphumela anobuthi utshwala kanye ne-nicotine, ukuvuvukala kobuchopho, yizifo ezihlukahlukene ezithathelwanayo. Ukuze uqonde ukuthi lesi sifo sihlasela umbono womuntu, kubalulekile ukuthola ukuthi kwenzekani ngesikhathi egula. Okuwukuphela kwendlela ukuthola.

Isakhiwo emsipheni optic sifana wire ngocingo. Omunye ekupheleni iya retina, kanti eyesibili ixhunywe ebuchosheni, lapho-ke umelela sonke Imininingwane vidiyo. Emsipheni optic yakhiwa inqwaba ukudluliswa Imicu yotshani zazo camera. Cabanga nje: ukushuba we "izintambo" akukho amamilimitha angu engaphezu kwemibili, futhi "izindikimba" abangaphezu kwesigidi. ingxenye ngayinye kwezintambo zesivikelo sesifuba unesibopho ukudluliselwa uhlobo oluthile isithombe. Endabeni ukufa kunezindatshana okuthiwa "esishintshashintshayo buthule". Man baphoqwa ukuba njalo ukushintsha engela umbono ukubona zonke izifundo evamile. Yingakho yoma we emsipheni optic kubangela eziningi ukungakhululeki: unciphise emkhakheni buka, kukhona ubuhlungu ukuthi kwenzeka ngesikhathi ukunyakaza iso. Kwezinye izimo, ekushintsheni umbono umbala.

Ngeshwa, yoma we emsipheni optic, izimpawu abalwe ngenhla - isifo okwamanje asikwazi ixazululwe ngokushesha. Umsebenzi oyinhloko ukuze ophthalmologist kuyinto "imvuselelo" abaningi yezinzwa. Kuphela kulesi simo kuyoba ukuthambekela okunamandla omuhle zokululama. Ngenxa yalesi noma aphendukele ekuthengiseni ukukhuthazwa emsipheni optic esebenzisa kushintshana kazibuthe, kagesi, kanye laser. Into esemqoka - uphethwe yini kusaqalwa lesi sifo. Lapho usebenzisa i-ukushukuma kazibuthe, ngcono umthamo wegazi ogciniwe, okuholela ukuphulukiswa inqubo okusheshayo. Uma yoma ngokwengxenye, ngemva 10-15 amaseshini, umbono wakho kuyothuthuka kakhulu. Electrostimulation kusho ukusetshenziswa kwe-pulse uhlobo kagesi. Kulokhu, inaliti ekhethekile ifakwe ngqo yeso, kanye nezinye electrode eqondiswa isikhumba. Kanye zindlela ezingenhla ekuphuzeni imithi ejwayelekile. Feza ukumpontshelwa igazi, lo dokotela linqume vasodilators. Kwezinye izimo iphendukele ukuhlinzwa.

Njengoba ubona, yoma optic, imithi okuyinto Kwenziwa izindlela ezahlukene - ngempela isifo esiyingozi kakhulu. Akunakusetshenziswa akudingeki ukungasinaki eziya ziba zimbi umbono wakho. Kufanele ngokushesha uxhumane kudokotela wezifo zamehlo, futhi uzonikhumbuza uphethwe yini futhi kusaqalwa kuzosiza ukwelapha lesi sifo.
