"Izimpukane" emehlweni - isibonakaliso sesifo esibucayi?

Umuntu ngamunye uzwela ngokuphindaphindiwe umuzwa okuthiwa ukubonakala "kwezindiza" emehlweni. Ngezinye izikhathi kungase kubonakale njengobufakazi besifo esithile esiyingozi. Kodwa-ke, ezimweni eziningi, "izimpukane" emehlweni zivela ngenxa yezizathu ezingenasici futhi aziwona uphawu lwe-pathology. Kodwa-ke, kwenzeka futhi lapho "izindiza" ezimnyama phambi kwamehlo kusho ukuthi umbono wesiphambano uphazamisekile. Futhi lokhu sekuvele kunenkinga ...

Ziyini lezi zimpawu ezingavamile? Izimpukane "ezimnyama" emehlweni, izindawo ezincane noma amachashazi avela lapho umuntu ebheka isizinda esingenalutho, njengesibhakabhaka esibhakabhaka noma udonga lwe-monochrome. Kungaphansi kwalesi simo ukuthi izinto ezincane kakhulu zibonakala zibonakala, lapho, lapho ikhanda lomuntu liphenduka noma amehlo ehamba, hamba ku-inertia ngendlela efanayo, ngemva kwalokho ahlehle futhi ahlele.

Abantu abaphilile, "izimpukane" emehlweni zingase zivele ngemuva kokulala isikhathi eside noma zibe mnyama - uma amehlo esetshenziselwa ukushintsha ukukhanya kokukhanyisa. Noma kunjalo, kunamacala amaningi lapho lesi sibonakaliso sibonisa izinkinga zezempilo ezingabangela izinkinga ezinkulu.

Lokhu kubandakanya i-osteochondrosis yomgogodla womlomo wesibeletho, okuyinto ebangela kakhulu ukubonakala kwe "izimpukane". Lokhu kungenxa yokuthi lesi sifo siphazamisa ukugeleza kwegazi emithanjeni ye-vertebral, kunciphisa ukucindezela kuzo. Lezi zingxube zegazi ziyaziwa ukunikeza igazi ne-oksijini ebuchosheni.

"Izimpukane" emehlo zingase zivele ezithombeni eziyingozi kakhulu, njengegazi elingaphakathi. Kulesi simo, amachashazi amhlophe avela phambi kwamehlo akho, okuyinto engase ibe yilapho kuphela ukubonakaliswa kwalesi sifo esiyingozi. Isizathu singase sibe yi-anemia, ngenxa yokuthi izinga le-oxygen engena ebuchosheni linciphisa. Ngenxa yalokho, ukuguquka kwesimiso kuphazamiseka, kuhlanganise ne-retina. I-anemia nayo iholela ekubukeni kwamachashazi amhlophe phambi kwamehlo nombono okhubazekile. Le "fad" enjalo ivela futhi ihlehlise ukucindezeleka kwegazi, lapho ukugcwalisa igazi kwegazi kunganele. Amachashazi amhlophe nawo avela ekulimaweni kwentloko.

Uma kwenzeka ubuthi obubi, izinto ezinobuthi zingathinta isimiso sezinzwa, kufaka phakathi ingxenye yaso, njenge- nertic optic. Lezi zifo ngeke ziholele ekuboneni "kwezindiza" kuphela, kodwa nakwezinye izifo ezibukwayo, ngokwesibonelo, ukuxhuma kwamehlo emehlweni.

Endabeni yesifo sikashukela esikhathele, kunomonakalo omkhulu ezitsheni ze-retina zamehlo nobuchopho, okuholela ekubukeni "kwezinmpukane". Inkinga enkulu yegazi ejwayelekile iholela ekulimazeni okufanayo kwamasongo ngenxa yokwehluleka ngokweqile. Kulesi simo, ukushintshaniswa phakathi kwesiteshi segazi kanye nezicubu buthakathaka. Kulesi simo, i-retina ingenye yezicubu ezibucayi kakhulu zalolu hlobo.

Uma "izimpukane" emehlweni zivela engxenyeni yesibili yokukhulelwa. Khona-ke ingakhuluma ngokutholakala kwesifo esinjenge-eclampsia, okuyinto engozini kokubili umama nengane.
