Isilonda se-corneal ukukhukhula noma ukuvuvukala okuvulekile ebusweni be- cornea . I-cornea yindawo ebonakalayo engxenyeni engaphambili yeso elisebenza njengefasitela esikubonayo. Iphinde igweme ukukhanya futhi inikeze ukuvikeleka kwezinye izingxenye zeso. Uma i-cornea igubha ngenxa yokutheleleka noma ukulimala, isilonda singase sikhule. Isilonda esinama-corneal yisimiso esibucayi okumelwe siphathwe ngokushesha ukuze sigweme izinkinga zombono ezihlala njalo.
Nakuba imithi emihle iyatholakala ekwelashweni, izilonda zamakholomu zingabangela ukulahlekelwa okukhulu kombono ngisho nokuphuphuthekisa.
Izimbangela
Izilonda ze-corneal zivame ukubangelwa amagciwane. Nakuba iso lomuntu livikelwe kahle yijwabu leso futhi lilambe, ama-germs kanye nama-bacteria angakwazi ukungena ku-cornea ngokusebenzisa ama-abrasions amancane uma ewonakele. Izilonda ze-corneal zivamile kubantu abagqoka ama-lens, ikakhulu uma bewagqoka ubusuku bonke. Ngokuvamile, ukujula kwe-cornea isilonda, isimo esiba sibi kakhulu. Isilonda esijulile singabangela ukulimala kwi-cornea, ukuvimbela ukukhanya ukungena esweni.
Izimbangela ezivamile zihlanganisa:
- Amabhaktheriya
- Ama-virus
- Ukulimala
- Isifo esiyingozi se-allergenic
- Isifungi
- Amoebas
- Ukuvalwa kwejwabu elikufanele
Izimpawu
Izimpawu zesilonda se-corneal zivame ukubonakala, ikakhulukazi uma isilonda sinzulu. Ngenxa yokuthi i-cornea ibucayi kakhulu, izilonda zamakholomu zivame ukuveza ubuhlungu obukhulu. Ngesinye isikhathi umbono ungaphumeleli, futhi iso lingase lidwengule futhi libomvu.
Kungabangela ubuhlungu ukubheka izibani ezikhanyayo. Uma unesinye sezibonakaliso ezilandelayo, kufanele uhlolwe udokotela weso ngokushesha:
- Ukubomvu
- Ubuhlungu
- Ukukhipha
- Ukukhishwa
- Indawo emhlophe e-cornea
- Umbono ogqamile
- Ukuvutha
- Itching
- Ukuzwela okukhanya
Ukuxilongwa
Ukuxilongwa kokuqala kubalulekile ekunakekeleni izilonda zamagciwane. Udokotela wakho uzobuza imibuzo ukucacisa imbangela yesilonda.
Amehlo akho kuzodingeka ahlolwe ngaphansi kwe-bio-microscope, ebizwa ngokuthi isibani sotshani . Idayi ekhethekile ingase ibekwe iso lakho ukusiza ekuxilongweni. Uma kungacacisi ukuthi yiyiphi imbangela eqondile, udokotela wakho angase ahlakulele isilonda ukuze aphathe kahle. Ngemuva kokuphazamisa iso lakho ngamaconsi akhethekile e-iso, amangqamuzana angase abhalwe ngokucophelela avela phezulu ukuze ahlolwe.
Ukwelapha
Ukwelashwa kwezilonda zamakhomikhali kufanele kube nobudlova, njengoba ezinye izilonda ziholela ekulahlekelweni kombono nokuphuphuthekisa. Ukwelashwa ngokuvamile kuhilela ama-antibiotics kanye nemithi yama-antiviral noma i-antifungal. I-steroid iso lamaconsi angaphinde anikezwe ukunciphisa ukuvuvukala. Abanye odokotela bathi i-topical eye ihlaselwa ukuze ifakwe izikhathi eziningana ngosuku kuze isilonda siphulukiswe ngokuphelele. Ezimweni ezimbi, iziguli zifakwa esibhedlela ukuze kutholakale ukwelashwa okufanele. Uma ukutheleleka kunenkani noma ushiye isibazi, ukufakelwa kwe-corneal kungadingeka ukubuyisela umbono. Uma ukwelashwa kunganikezwa, ubumpumputhe noma ukulahlekelwa ngokuphelele kweso kungenzeka. Izithako ezithile, ezinjengevithamini C, zingahle zenziwe ukuba zinciphise ukonakala kwe-corneal. Uma isilonda singaphilisi ngokujwayelekile ngemithi ejwayelekile, ngezinye izikhathi i- amniotic membrane izobekwa kwi-cornea izinsuku ezingu-7-10.
