Yintoni i-corneal ulcer?

Ngaphambili kweliso kukho umaleko ocacileyo wethishu ebizwa ngokuba yicornea. I-cornea ifana nefestile evumela ukukhanya kungene kwiso. Iinyembezi zikhusela i-cornea kwiibhaktheriya, iintsholongwane kunye nefungi.

I-corneal ulcer sisilonda esivulekileyo esakha kwi-cornea. Ngokuqhelekileyo kubangelwa usulelo. Nokuba ukwenzakala okuncinci kwiso okanye ukhukuliseko lomhlaba olubangelwa kukunxiba iilensi zonxibelelwano ixesha elide kunokubangela usulelo.

Kutheni le nto izilonda zekorale zikhula?

Unobangela ophambili wezilonda zomqala kukusuleleka.

Acanthamoeba keratitis

Olu suleleko luhlala luvela kubathwali beelensi zonxibelelwano. Sisifo se-amoebic kwaye, nangona sinqabile, sinokukhokelela kubumfama.

Herpes simplex keratitis

I-Herpes simplex keratitis sisifo sentsholongwane esibangela ukuphindaphinda kwezilonda okanye izilonda kwiso. Zininzi izinto ezinokubangela ukuvela, kubandakanya uxinzelelo, ukukhanya elangeni ixesha elide, okanye nantoni na ethoba amandla kwintsholongwane.

I-fungal keratitis

Usulelo lokungunda luyenzeka emva kokwenzakala kwi-cornea ebandakanya isityalo okanye izinto zezityalo. I-fungal keratitis inokuphinda ikhule kubantu abane-immune system ebuthathaka.

Ezinye izizathu

Ezinye izizathu zezilonda ze-corneal zibandakanya:

• iliso elomileyo
• ukwenzakala kwamehlo
• ukuphazamiseka ukudumba
• unxibe iilensi ezingadityaniswanga
• Ukunqongophala kukavithamini A.

Abantu abanxiba iilensi zonxibelelwano ezithambileyo eziphelelwe lixesha okanye abanxiba iilensi zonxibelelwano ezilahlwayo ixesha elide (kubandakanywa ubusuku bonke) basemngciphekweni omkhulu wokukhula kwezilonda ze-corneal.

Zithini iimpawu zesilonda esikufutshane?

Unokuqaphela iimpawu zentsholongwane ngaphambi kokuba uqaphele isilonda se-corneal. Iimpawu zosulelo zibandakanya:

• ukurhawuzelela iliso
• iliso elinamanzi
• ukukhutshwa okufana nobofu kwiliso
• ukutshisa okanye ukubetha kwamehlo
• iliso elibomvu okanye elipinki
• uvakalelo ekukhanyeni

Iimpawu kunye neempawu zesilonda se-corneal ngokwawo zibandakanya:

• ukudumba kwamehlo
• Iliso elibuhlungu
• ukukrazula okugqithisileyo
• ukungaboni kakuhle
• indawo emhlophe kwi-cornea yakho
• ukudumba kweenkophe
• ubofu okanye ukukhupha iliso
• uvakalelo ekukhanyeni
• uziva ngathi kukho into esweni lakho (uvakalelo lwangaphandle)

Zonke iimpawu zezilonda zomqala zibukhali kwaye kufuneka zinyangwe ngokukhawuleza ukuthintela ukungaboni. Isilonda esikrwada ngokwaso sijongeka njengendawo engwevu okanye emhlophe okanye ibala kwi-cornea edla ngokubonakala. Ezinye izilonda ze-corneal zincinci kakhulu ukuba zingaboni ngaphandle kokukhulisa, kodwa uya kuziva iimpawu.

Kufunyaniswa njani ukuba unesilonda esikrwada?

Ugqirha wamehlo unokufumanisa izilonda ze-corneal ngexesha lovavanyo lwamehlo.

Olunye uvavanyo olusetyenziselwa ukukhangela isilonda se-corneal isilonda se-fluorescein. Kolu vavanyo, ugqirha wamehlo ubeka idonsi yedayi eorenji kwisiqwengana sephepha lokucima. Emva koko, ugqirha ugqithisela idayi elisweni lakho ngokuchukumisa kancinci iphepha lokucima kumphezulu wamehlo akho. Emva koko ugqirha usebenzisa imicroscope ebizwa ngokuba sisibane esikrelekrele ukukhanyisa ukukhanya okukhethekileyo kwiso lakho ukujonga nayiphi na indawo eyonakeleyo kwi-cornea yakho. Umonakalo we-Corneal uya kubonisa okuluhlaza xa ukukhanya kwe-violet kukhanya kuwo.

Ukuba unesilonda kwi-cornea yakho, ugqirha wakho wamehlo uya kuphanda ukuze afumane isizathu. Ukwenza oko, ugqirha unokukrala iliso lakho ngamathontsi wamehlo, emva koko ulusule ngobunono isilonda ukuze ufumane isampuli yovavanyo. Uvavanyo luya kubonisa ukuba isilonda siqulathe ibhaktiriya, ifungi, okanye intsholongwane.

Luthini unyango lwesilonda esikrwada?

Nje ukuba ugqirha wakho wamehlo afumanise unobangela wesilonda esine-corneal ulcer, banokumisela iyeza lokulwa isibulala-ntsholongwane, i-antifungal, okanye i-antiviral eye ukunyanga ingxaki ekhoyo. Ukuba ngaba usuleleko alulunganga, ugqirha wakho unokukubeka kumachaphaza wamehlo okulwa ne-antibacterial ngelixa bevavanya izilonda zesilonda ukufumanisa unobangela wosulelo. Ukongeza, ukuba iliso lakho lidumbile kwaye lidumbile, kuya kufuneka usebenzise i-corticosteroid eye eye.

Ngexesha lonyango, ugqirha wakho uya kukucela ukuba ugweme oku kulandelayo:

• ukunxiba iilensi zonxibelelwano
• uthambisile
• ukuthatha amanye amayeza
• ukuchukumisa iliso lakho ngokungeyomfuneko

Ukutshintshwa kweCorneal

Kwiimeko ezinzima, i-corneal ulcer inokuqinisekisa ukufakelwa kwe-corneal. Ukufakelwa kwe-corneal kubandakanya ukususwa kotyando lwezihlunu ze-corneal kunye nokutshintshwa kwezicubu zomnikeli. Ngokwe-Mayo Clinic, ukufakelwa kwe-corneal yinkqubo ekhuselekileyo. Kodwa njengayo nayiphi na inkqubo yotyando, kukho iingozi. Olu tyando lunokubangela iingxaki zempilo zexesha elizayo ezinje:

• ukwaliwa kwethishu yabanikeli
• ukukhula kweglaucoma (uxinzelelo ngaphakathi kwamehlo)
• usulelo lwamehlo
• ikati (ilifu lelensi yamehlo)
• ukudumba kwenwebu

Ndiluthintela njani isilonda esikufutshane?

Indlela efanelekileyo yokuthintela izilonda ze-corneal ukufuna unyango ngokukhawuleza xa uhlakulela nayiphi na impawu yosulelo lwamehlo okanye ngokukhawuleza xa iliso lakho lilimele.

Amanye amanyathelo okhuseleko abandakanya:

• ukunqanda ukulala ngelixa unxibe iilensi zakho zonxibelelwano
• ukucoca nokucoca abafowunelwa ngaphambi nasemva kokuzinxiba
• ukuhlamba amehlo akho ukususa naziphi na izinto zangaphandle
• ukuhlamba izandla ngaphambi kokuchukumisa amehlo akho

Ithini imbono yexesha elide?

Abanye abantu banokuhlakulela ukulahleka okukhulu kombono kunye nokuphazamiseka okubonakalayo ngenxa yokunqongophala kwi-retina. Izilonda ezinamachaphaza egazi nazo zinokubangela ukonakala okusisigxina kwiso. Kwiimeko ezinqabileyo, iliso lonke linokuba nomonakalo.

Nangona izilonda ze-corneal ziyanyangeka, kwaye uninzi lwabantu luphulukana kakuhle emva konyango, ukuncipha kwamehlo kunokwenzeka.
