Iso elibomvu nelibuhlungu? Ungase ube nesilonda se-cornea, isilonda esilimazayo ebusweni beso esibangelwa ukuhlukumezeka noma ukutheleleka. Kungcono ukubonana nodokotela wamehlo ngokushesha ngoba lesi simo, ngokuvamile esiyingozi, singabangela izinkinga futhi sibangele ukulahlekelwa okungenakulungiseka kokubona kahle, noma ngisho nokungaboni ezimweni ezimbi kakhulu.

Incazelo

Izilonda zamehlo yizilonda ze-cornea, noma izilonda ze-cornea. Zibangelwa isilonda esibangelwa ukulahlekelwa okuthile, noma izilonda, ezimboza ngokujulile noma kancane lolu lwelwesi olukhanyayo olumboze umfundi ne-iris. Ukuvuvukala okuyisisekelo kungase kube buhlungu kakhulu.

Izimbangela

Isilonda se-cornea singavela kulandela ukuhlukumezeka kweso (ukuklwebheka nje, ukunwaya kwekati, igatsha esweni…) noma ukutheleleka.  

Ama-microbial agents ahlukene angabangela izilonda zobunzima obuhlukahlukene. Amagciwane afana ne-herpes virus athinteka ezilonda ezingapheli. Ukuvuvukala kwe-cornea (keratitis) nakho kungabangelwa amagciwane (Pseudomonas, Staphylococcus aureus, Chlamydia trachomatis, noma i-streptococcus, i-pneumococcus …), ukhunta noma i-amoeba.

Ukuba khona komzimba wangaphandle esweni, ukuhlikihlwa kwenkophe emile (i-trichiasis) noma ukuqagela kwamakhemikhali nakho kungenzeka kubangele izilonda.

Emazweni asathuthuka, izilonda ezibangelwa ukuntuleka kukavithamini A ziyimbangela enkulu yobumpumputhe.

Abantu abathintekayo

Izilonda ze-Corneal yi-pathologies evamile kunoma yisiphi isikhathi. 

I-Trachoma, ukutheleleka kwamehlo ngamagciwane, Chlamydia trachomatis, kuyinkinga yangempela yezempilo yomphakathi emazweni asathuthuka. Ukutheleleka okuphindaphindiwe ngempela kubangela izilonda ze-cornea nemiphumela emibi kakhulu. Ngokusho kwe-WHO, i-trachoma ibangela ubumpumputhe nokukhubazeka kokubona, okuthinte abantu ababalelwa ezigidini eziyi-1,9 ngo-2016.

Izici zengozi

Ukugqoka ama-contact lens kwandisa ingozi yokutheleleka, ikakhulukazi uma imithetho yokusetshenziswa nenhlanzeko ingahlonishwa: ukugqokwa isikhathi eside ngaphezu kwesikhathi esinqunyiwe, ukukhishwa okwanele kokubulala amagciwane ... Ukungcoliswa yi-amoeba emachibini okubhukuda kungaba imbangela. imbangela yezilonda.

Ukucasuka ngenxa yamehlo omile noma ukuhluleka ukuvala ijwabu leso (ikakhulukazi uma kwenzeka ubhekisa ijwabu leso libheke esweni, noma i-entropion) nakho kungadlulela ku-cornea ulcer.

Imisebenzi echayeka ekuqageleni kwemikhiqizo ebolayo noma izinhlayiya, noma ngisho nokushisela, ezinye izici zobungozi.

kwesifo

Ukuxilongwa kusekelwe ekuhlolweni okwenziwa yi-ophthalmologist. Ukuhlolwa kwereferensi kwenziwa kusetshenziswa i-biomicroscope, noma isibani esisikiwe. Ukuze kuhlolwe umonakalo ku-cornea, kwenziwa ngokukhanya okuluhlaza okwesibhakabhaka, ngemuva kokufakwa kweconsi iso eliqukethe udayi, i-fluorescein, ebopha izilonda futhi ibenze babonakale beluhlaza.

Amasampula kufanele athathwe ukuze kutholakale i-microbial agent ebandakanyeka ezilonda ezithathelwanayo.

Lapho isilonda sijula ​​yilapho izimpawu ziba nzima kakhulu. Iso elinezilonda libomvu futhi libuhlungu, futhi isilonda sikwenza kube sengathi kunomzimba wangaphandle esweni. 

Ezinye izimpawu zivame ukuhlotshaniswa:

• ukuzwela ngokweqile ekukhanyeni, noma i-photophobia,
• izinyembezi
• ukungaboni kahle ngokuncipha kokubona,
• ngezinhlobo ezinzima kakhulu, ukunqwabelana kobomvu ngemuva kwe-cornea (hypopion).

Evolution

Kuvamise ukuba kuhle uma isilonda sikha phezulu, kodwa iso lingase lihlale liguqubele ngokwengxenye kulandela izibazi. Ibala elikhanyayo, noma umcamelo, ayibangeli ukungakhululeki okubukwayo uma incane futhi i-peripheral. Uma inkulu futhi imaphakathi, ibangela ukuncipha kokubona kahle. 

Inkinga engenzeka ukusabalala kokutheleleka ekujuleni. Ezimweni ezimbi kakhulu, i-cornea puncture kanye nezicubu zamehlo ziyabhujiswa. Ngakho-ke isilonda esingalashiwe singaholela ebumpumputheni.

Ukwelashwa kwe-acute cornea ulcer kufanele kuqalwe ngokushesha ngangokunokwenzeka. Ngokuya ngobunzima bayo, i-ophthalomogue izokwahlulela ukuthi kuyadingeka yini ukulaliswa esibhedlela.

Ilihlo

Njengokwelashwa kokuhlasela, amaconsi e-antiseptic iso kufanele afakwe esweni kaningi, kwesinye isikhathi njalo ngehora amahora angama-24 okuqala.

Amaconsi eso e-Broad-spectrum antibiotic angasetshenziswa njengomugqa wokuqala, inqobo nje uma i-causative organism ingakabonwa. Khona-ke, i-ophthalmologist izobeka ama-antibiotic akhethekile, ama-antiviral noma amaconsi e-antifungal iso.

Amaconsi iso njenge-atropine noma i-scopolamine, enweba umfundi, angasiza ekudambiseni ubuhlungu.

Ngokuvamile uzodinga ukuqhubeka nokunikeza amaconsi esweni njengendlela yokwelapha isilonda kuze kube yilapho sesipholile ngokuphelele.

Ubuciko

Ezimweni ezimbi kakhulu, ukufakelwa kwe-cornea kungase kudingeke, ikakhulukazi lapho i-cornea ibhobokile. Ukufakelwa ulwelwesi lwe-amniotic (oluvala i-placenta kanye nombungu kwabesifazane abakhulelwe) ngezinye izikhathi kuyaboniswa, lolu lwelwesi lucebile kakhulu ngezinto eziphilisayo.

Izinyathelo ezimbalwa ezilula zokuphepha zingavimbela izilonda eziningi! Nsuku zonke, ngaphezu kwakho konke umbuzo wokuhlonipha imiyalelo yokugcina ama-lens, ukuvikela amehlo ekuhlaselweni (ilanga, intuthu, uthuli, isimo somoya, umoya, njll.) okunesibopho sokuwenza buthaka, mhlawumbe usebenzisa izinyembezi zokwenziwa, njll. .

Ukugqoka izibuko noma imaskhi yokuzivikela kufanele kuhlonishwe ngemisebenzi ebeka iso ekuhloleni noma emisebeni.
