Siyini isilonda se- corneal?

Phambili kweso kukhona ungqimba olucacile lwezicubu ezibizwa ngokuthi i-cornea. I-cornea ifana newindi elivumela ukukhanya ukuthi kungene esweni. Izinyembezi zivikela i-cornea kumabhaktheriya, amagciwane kanye nesikhunta.

Isilonda se-corneal yisilonda esivulekile esakha ku-cornea. Ngokuvamile kubangelwa ukutheleleka. Ngisho nokulimala okuncane esweni noma ekugugulekeni komhlaba okubangelwa ukugqoka amalensi athinta isikhathi eside kungaholela ezifweni.

Kungani izilonda ze-corneal zikhula?

Isizathu esiyinhloko sezilonda zamakhaza ukutheleleka.

I-Acanthamoeba keratitis

Lokhu kutheleleka kuvame ukuvela kubathwali belensi yokuxhumana. Kuyisifo se-amoebic futhi, yize kungavamile, kungaholela ekungaboni.

I-Herpes simplex keratitis

I-Herpes simplex keratitis ukutheleleka ngegciwane okubangela ukuqhuma okuphindaphindiwe kwezilonda noma izilonda esweni. Izinto eziningana zingadala ukuqhuma, kufaka phakathi ukucindezeleka, ukukhanya kwelanga isikhathi eside, noma yini eyenza buthakathaka amasosha omzimba.

I-fungal keratitis

Lokhu kutheleleka kwefungal kuvela ngemuva kokulimala ku-cornea okubandakanya okokusebenza kwesitshalo noma kwesitshalo. I-fungal keratitis nayo ingakhula kubantu abanamasosha omzimba abuthakathaka.

Ezinye izimbangela

Ezinye izimbangela zezilonda ze-corneal zihlanganisa:

• iso elomile
• ukulimala kweso
• iziyaluyalu zokuvuvukala
• egqoke amalensi wokuxhumana angadalulwanga
• ukushoda kukavithamini A

Abantu abagqoka amalensi athintwayo aphelelwe yisikhathi noma abafaka amalensi okuxhumana alahlwayo isikhathi eside (kufaka phakathi ubusuku bonke) basengozini enkulu yokuthola izilonda zamakhaza.

Ziyini izimpawu zesilonda se-corneal?

Ungaqaphela izimpawu zokutheleleka ngaphambi kokuthi wazi isilonda se-corneal. Izimpawu zokutheleleka zifaka:

• iso elilumayo
• iso elinamanzi
• ukuphuma okufana nobovu esweni
• umuzwa ovuthayo noma olumayo esweni
• iso elibomvu noma elibomvana
• ukuzwela ekukhanyeni

Izimpawu nezimpawu zesilonda se-corneal uqobo zifaka:

• ukuvuvukala kweso
• iso elibuhlungu
• ukudabuka ngokweqile
• ukungaboni kahle
• indawo emhlophe ku-cornea yakho
• zivuvukile izinkophe
• ubomvu noma ukukhishwa kwamehlo
• ukuzwela ekukhanyeni
• ukuzwa sengathi kukhona okusesweni lakho (ukuzwa komzimba wangaphandle)

Zonke izimpawu zezilonda zamakhaza zinzima futhi kufanele zilashwe ngokushesha ukuvimbela ukungaboni. I-corneal ulcer uqobo ibukeka njengendawo empunga noma emhlophe noma ibala ku-cornea evame ukubonakala. Ezinye izilonda ze-corneal zincane kakhulu ukuba zingabonwa ngaphandle kokukhuliswa, kodwa uzozizwa izimpawu.

Kutholakala kanjani ukuthi i-corneal ulcer?

Udokotela wamehlo angaxilonga izilonda ze-corneal ngesikhathi sokuhlolwa kwamehlo.

Olunye uvivinyo olusetshenziselwa ukuhlola i-corneal ulcer ibala le-fluorescein eye. Kulesi sivivinyo, udokotela wamehlo ubeka ithonsi likadayi owolintshi engxenyeni encane yephepha elicimayo. Ngemuva kwalokho, udokotela udlulisela udayi esweni lakho ngokuthinta kancane iphepha lokususa ebusweni beso lakho. Ngemuva kwalokho udokotela usebenzisa imakhroskophu ebizwa nge-slit-lamp ukukhanyisa isibani esikhethekile se-violet esweni lakho ukubheka noma yiziphi izindawo ezilimele ku-cornea yakho. Ukulimala kwe-Corneal kuzobonisa okuluhlaza lapho ukukhanya kwe-violet kukhanya kuwo.

Uma unesilonda ku-cornea yakho, udokotela wakho wamehlo uzophenya ukuthola imbangela yaso. Ukwenza lokho, udokotela angakhubaza iso lakho ngamaconsi wamehlo, bese ulusula ngobumnene isilonda ukuze uthole isampula sokuhlolwa. Ukuhlolwa kuzobonisa ukuthi ngabe isilonda siqukethe amabhaktheriya, isikhunta, noma igciwane.

Yini ukwelashwa kwesilonda se-corneal?

Lapho nje udokotela wamehlo wakho ethola imbangela yesilonda se-corneal, bangakunikeza umuthi wamehlo wokulwa namagciwane, owokubulala izinhlungu noma we-antiviral ukwelapha inkinga engaphansi. Uma ukutheleleka kukubi, udokotela wakho angakufaka kumaconsi e-antibacterial eye ngenkathi evivinya ukusikwa kwesilonda ukuthola imbangela yokutheleleka. Ngaphezu kwalokho, uma iso lakho livuvukile futhi livuvukile, kungadingeka ukuthi usebenzise amaconsi wamehlo e-corticosteroid.

Ngesikhathi sokwelashwa, udokotela wakho uzokucela ukuthi ugweme okulandelayo:

• ukugqoka amalensi wokuxhumana
• egqoke izimonyo
• ukuthatha eminye imithi
• ukuthinta iso lakho ngokungadingekile

Ukufakelwa kwe-Corneal

Ezimweni ezinzima, i-corneal ulcer ingaqinisekisa ukufakelwa kwe-corneal. Ukufakelwa kabusha kwe-corneal kufaka ukususwa kokuhlinzwa kwezicubu ze-corneal nokufakwa esikhundleni sazo ngezicubu zabanikeli. Ngokusho kweMayo Clinic, ukufakelwa i-corneal inqubo ephephile impela. Kepha njenganoma iyiphi inqubo yokuhlinzwa, kunezingozi. Lokhu kuhlinzwa kungadala izingqinamba zezempilo zesikhathi esizayo ezifana nalezi:

• ukwenqatshwa kwezicubu zomnikeli
• ukuthuthukiswa kwe-glaucoma (ingcindezi ngaphakathi kweso)
• ukutheleleka kweso
• inkalakatha (ukufiphalisa ilensi yeso)
• ukuvuvukala kwe-cornea

Ngisivimbela kanjani isilonda se- corneal?

Indlela engcono yokuvimbela izilonda ze-corneal ukufuna ukwelashwa ngokushesha nje lapho uba nesifo sokutheleleka kweso noma ngokushesha lapho iso lakho lilimele.

Ezinye izindlela eziwusizo zokuvimbela zifaka:

• ukugwema ukulala ngenkathi ugqoke amalensi wakho oxhumana nawo
• ukuhlanza nokuhlanza oxhumana nabo ngaphambi nangemva kokukugqoka
• uhlambulule amehlo akho ukuze ususe noma yiziphi izinto zangaphandle
• ukugeza izandla ngaphambi kokuthinta amehlo akho

Uyini umbono wesikhathi eside?

Abanye abantu bangaphinde bahlakulele ukulahleka okukhulu kombono kanye nokuvinjelwa okubukwayo ngenxa yokulimala ngaphezulu kwe-retina. Izilonda ze-Corneal nazo zingadala ukulimala okungapheli esweni. Ezimweni ezingavamile, iso lonke lingalimala.

Yize izilonda ze-corneal zilapheka, futhi abantu abaningi belulama kahle ngemuva kokwelashwa, ukuncipha kwamehlo kungenzeka.
