Izilonda ze-Corneal kanye nezifo

I-cornea yizicubu ezicacile ngaphambili kweso. Isilonda se-corneal yisilonda esivulekile engxenyeni engaphandle ye-cornea. Kuvame ukubangelwa ukutheleleka. Ekuqaleni, i-corneal ulcer ingabonakala njenge-conjunctivitis, noma iso elibomvana.

Izilonda ze-Corneal zivame ukubangelwa ukutheleleka ngamagciwane, ama-virus, isikhunta noma i-parasite.

• I-Acanthamoeba keratitis ivela kubasebenzisi belensi yokuxhumana. Kungenzeka kakhulu ukuthi abantu abazenzele izixazululo zabo zokuhlanza.
• I-fungal keratitis ingenzeka ngemuva kokulimala kwe-corneal okubandakanya izinto zokutshala. Kungenzeka futhi kubantu abanamasosha omzimba acindezelwe.
• I-Herpes simplex keratitis igciwane lesandulela ngculaza elibi kakhulu. Kungadala ukuhlaselwa okuphindaphindiwe okubangelwa yingcindezi, ukuvezwa yilanga, noma yisiphi isimo esinciphisa ukuphendula komzimba.

Izilonda ze-Corneal noma izifo zingabangelwa yi:

• Izinkophe ezingavali yonke indawo, njengokukhubazeka kweBell
• Imizimba yangaphandle esweni
• Imihuzuko (imihuzuko) ebusweni beso
• Amehlo omile kakhulu
• Isifo esibi somzimba esibi
• Izinkinga ezahlukahlukene zokuvuvukala

Ukugqoka amalensi wokuxhumana, ikakhulukazi othintana nabo abathambile abashiywa ubusuku bonke, kungadala isilonda se-corneal.

Izimpawu zokutheleleka noma izilonda ze-cornea zifaka:

• Ukufiphala noma ukungaboni kahle
• Iso elivela libomvu noma igazi
• Ukulunywa nokukhipha
• Ukuzwela ekukhanyeni (photophobia)
• Amehlo abuhlungu kakhulu namanzi
• Isikhumba esimhlophe ku-cornea

Umhlinzeki wakho wezokunakekelwa kwempilo angenza lezi zivivinyo ezilandelayo:

• Ukuhlolwa kokuchithwa kusuka ku-ulcer
• Ibala le-fluorescein le-cornea
• I-Keratometry (elinganisa ijika le-cornea)
• Impendulo ye-Pupillary reflex
• Ukuhlolwa kwe-Refraction
• Ukuhlolwa kwesibani
• Ukuhlolwa kweso elomile
• Ubukhali obubukwayo

Ukuhlolwa kwegazi ukuhlola ukuphazamiseka kokuvuvukala nakho kungadingeka.

Ukwelashwa kwezilonda ze-corneal kanye nokutheleleka kuya ngesizathu. Ukwelashwa kufanele kuqalwe ngokushesha okukhulu ukuvimbela ukubola kwe-cornea.

Uma imbangela yangempela ingaziwa, unganikezwa amaconsi ama-antibiotic asebenza nezinhlobo eziningi zamagciwane.

Lapho imbangela ngqo isaziwa, unganikezwa amaconsi alapha amabhaktheriya, i-herpes, amanye amagciwane, noma ukhunta. Izilonda ezinzima kwesinye isikhathi zidinga ukufakelwa kwe-corneal.

Amaconsi wamehlo e-Corticosteroid angasetshenziswa ukunciphisa ukuvuvukala nokuvuvukala ezimweni ezithile.

Umhlinzeki wakho futhi angancoma ukuthi:

• Gwema ukwakheka kwamehlo.
• UNGAYIFAKI nhlobo i-lens, ikakhulukazi lapho ulele.
• Thatha imithi yezinhlungu.
• Gqoka izibuko zokuzivikela.

Abantu abaningi balulama ngokuphelele futhi banoshintsho oluncane embonweni. Kodwa-ke, i-corneal ulcer noma ukutheleleka kungadala ukulimala kwesikhathi eside futhi kuthinte umbono.

Izilonda ze-corneal ezingalashwa kanye nokutheleleka kungaholela ku:

• Ukulahleka kweso (okungajwayelekile)
• Ukulahleka kombono okukhulu
• Izibazi ku-cornea

Shayela umhlinzeki wakho uma:

• Unezimpawu zezilonda ze-corneal noma ukutheleleka.
• Utholwe unalesi simo futhi izimpawu zakho ziba zimbi kakhulu ngemuva kokwelashwa.
• Umbono wakho uthintekile.
• Uba nobuhlungu beso obunzima noma obubi kakhulu.
• Izinkophe zakho noma isikhumba esiseduze kwamehlo akho siyavuvukala noma sibe bomvu.
• Unekhanda ngaphezu kwezinye izimpawu zakho.

Izinto ongazenza ukuvimbela lesi simo zifaka:

• Geza izandla zakho kahle lapho uphatha ama-lens oxhumana nawo.
• Gwema ukugqoka amalensi oxhumana naye ubusuku bonke.
• Thola ukwelashwa ngokushesha kokutheleleka kweso ukuvimbela izilonda ekubunjweni.
