Uke waba nendawo ecasulayo ebonakala embonweni wakho? Ama-Cobwebs, izindandatho, amabala kanye nama-floater ngamagama asetshenziselwa ukuchaza izinto ezincane esizibona ngombono wethu kumbono wethu noma insimu ebonakalayo. Abaningi bethu babone eyodwa noma emibili esikhathini sethu sokuphila kanti abanye bethu bangase bakhathazeke yizinga elikhulu kakhulu.
Yiziphi Izikhukhula?
Ama-Floaters yigama elivamile elinikezwe izinto esizibona ngezikhathi ezithile embonweni wethu.
Izikhukhula zivame ukuvela ku-vitreous humor, into efana ne-gel igcwalisa isikhumba ngaphakathi kweso lethu . I-vitreous iqinile futhi icacile lapho sisebancane. Kodwa-ke, njengoba sikhula, i-vitreous ijwayele ukuguqula ukuvumelana nokukhipha kancane kancane. Uma lokhu kwenzeka, i-gel ingase iqiniseke noma ithuthukise imigqa noma izindawo ezizungeze ngaphakathi kweso. Lezi zicubu zezincuba ziba nzima kakhulu ngakho ukukhanya angeke kuzikhanyise kahle kakhulu. Ngenxa yalokho, ukukhanya kufaka ilanga kanye nezicubu ezinamahloni okwenza isithunzi phezu kwe- retina futhi sibona njengethunzi noma icwecwe eliphuma emkhathini.
Izikhukhula zingabonakala njengalokhu okulandelayo:
- ama-specs
- amachashazi
- izintambo noma imigqa
- izindandatho
- cobwebs
Yini Eyenza Izikhukhula Zibaluleke Kakhulu?
Ama-Floaters abonakala kakhulu lapho ebuka isikrini sekhompyutha noma ngaphezulu, ebheka isibhakabhaka esibhakabhaka esibhakabhaka. Abadwebi bezobuchwepheshe bavame ukukhononda ngokubona izibhakabhaka ngoba bahlale bebuka izizinda ezinkulu ezimhlophe.
Izikhukhula zivame ukuthutha. Uma ususa iso lakho ukugxila kubo, bavame ukushintshela endaweni ehlukile ngokushesha. Bangakwazi ukuhamba bese bezungeza ngaphakathi kweso lakho kodwa kaningi nje ukunyakaza kwamehlo akho okukunika umuzwa wokuthi i-floater iyahamba.
Iningi lethu livame ukungazinaki iziqu ezincane noma nje ukuzisebenzisa.
Ubuchopho bethu buhle kakhulu ngokungazinaki. Iningi lezintambo zivame ukungena ngaphansi kwamehlo ethu ngenxa yodlava kodwa ngezinye izikhathi, ukukhanya okulungile ngakwesokudla kungabangela ukuba kubonakale.
Ingabe ama-Floaters awonakele?
Iningi lezintambo ezihamba phambili ziyingozi. Kodwa-ke, ngezinye izikhathi ukugeleza kungaba uphawu lwezinto eziyingozi kakhulu. Ukunyuka okungazelelwe kwezinto ezihamba phambili, ukwanda kwesayizi se-floater noma izibani ezintsha ezikhanyayo ezihambisana ne-floater kungaba isibonakaliso sezinyembezi noma izinqola zokubuyisela. Inyembezi noma inqola yokuhlenga isisindo noma ukuhlukaniswa kwe-retina, izicubu ezinamahlombe ezinamahlombe ezinamahlombe ezithinta ngemuva kwe-eyeball. Esimweni sokunakekelwa kwamehlo, izinyembezi noma izinqola kubhekwa njengesimo esiphuthumayo. Ukuphumelela kokwelashwa kwezinyembezi noma izinqola kuncike engxenyeni ye-retina ehilelekile futhi ubude besikhathi sokwelapha seqalile.
Izimbangela
Isizathu esivame kakhulu sezintambo ezintsha kukhona ukuthuthukiswa kwe-posterior vitreous detachment (PVD). Ku-PVD, i-vitreous ingase ihluke ngempela kwi-retina. Nakuba i-PVD ingenzeka ngenxa yokuhlukumezeka, ivame kakhulu kubantu abaphakathi kweminyaka engu-50. Ukuguga kubangela ukuthi i-vitreous ihlehlise futhi ihlukane ne-retina.
Uma le nqubo ivela ngokushesha, ingakwazi ukudonsa ku-retina, ebangela izimpawu zezibani ezikhanyayo. Uma idonsa kanzima ngokwanele, izinyembezi ze-retinal zingenzeka. Umswakama ungakha ngemuva kwe-retina, ukuwuhlukanisa nodonga lweso.
Ezinye izimbangela zezintambo zingaba nesifo sikashukela sikashukela, ukuphuma noma ukubola kwesibindi, ukuvuvukala kwe-vitreous, ukulimala kwamehlo, nama- tumor eye . Uma uhlakulela izintambo ezintsha kufanele ubheke ngokushesha udokotela wezandla ukuze uthole ukuhlolwa okuphelele. Udokotela uzohlola ngemuva kweso lakho ngokufaka emaceleni amaconsi angama-eye ahlotshisiwe ehlotsheni elizokhulisa umfundi.
Izwi elivela
Uma ngokungazelelwe uqaphele indawo noma ugxile embonweni wakho, ungethuki. Le ndawo ingase ibe yi-floater, inqwaba yezicubu ezizungeze ngaphakathi kweso lakho. Iningi lezintantathu alinakulimaza ngokuphelele. Kodwa-ke, uma ngokungazelelwe uqaphele ukukhuphuka okungazelelwe kwamapulangwe noma ukukhanya kokukhanya, kungcono ukuqaphela udokotela wakho we-eye.
