Ubuhlungu Emva kokulimala
Ukuvuthwa kwe-corneal ephindaphindiweyo kukuvula okanye ukuphazamiseka okuqhubekayo kweeseli kwindawo engaphezulu kwe- cornea . Iiseli ezenza uluhlu oluphezulu lwe-cornea zibizwa ngokuba ngama-epithelial cells. Ezi seli-epithelial ziboshwe ngokuqinile kwi-cornea ngoluhlu olungaphantsi, olubizwa ngokuba ngumgca we-Bowman. Umsebenzi we-Bowman ubeka njenge-glue ukubamba iiseli ze-epithelial ngokukhawuleza kwiso.
Uluhlu lwe Bowman lwenziwa ngu-collagen. Xa lo buncwane bonakaliswe okanye bunobungozi, uluhlu oluphezulu lweeseli ze-epithelial alukwazi ukuphilisa ngokufanelekileyo kwaye aluzange lubophe ngokuchanekileyo kwisalathisi se Bowman. Ngenxa yoko, iiseli ze-epithelial ziphuma kalula. Iiseli ze-Epithelial zihlaziywa kodwa zinyanzelwanga kakuhle kwi-Bowman's layout. Ukususela ngamaxesha, iiseli ze-epithelial ziya kuwela ngokulula, zishiye isifo esivulekileyo esifana nokukhangela okanye ukukhishwa kweso.
Izinto zobungozi
Ukukhukhula kwamanzi okuphindaphindiweyo ngokuqhelekileyo kubangelwa ukulimala kwangaphambili kwi-cornea ne-Bowman's layer. Ukuba uyalimaza iso lakho ngethuluzi elibukhali okanye unobuncwane okanye uxinzelele iphepha elisezantsi kwiphulo elibangelwa ukuchithwa kwamanzi, usengozini yokuphuhlisa emva koko ukukhula kwe-corneal erosion.
Abantu abanezifo ezithile ze-dystrophies (i-epithelial basement membrane dystrophy (EBMD), i-Reis-Bucklers dystrophy, i-lattice dystrophy, i-dystrophy e-granular, i-dystrophy ye-Fuch's endothelial).
Kula bantu, inxalenye yangaphambili okanye yangaphambili ye-cornea ingaba nesifo, ebangela ukuba iiseli ze-epithelial zingabophi ngokuqinile kwi-cornea. Ngamanye amaxesha bafumana ukukhukuliseka kwangoko kodwa ukuba abantu abanesifo se-membrane isifo esingaphantsi kweso, banomngcipheko ophezulu wokuphucula izidumbu eziqhelekileyo ekuhambeni kwexesha ebomini.
Abo banesifo sengqondo esomeleleyo banokuthi babe nomngcipheko omkhulu wokuhlakulela iziganeko eziphindaphindiweyo ukuba baye bafumana ukulimala kwangaphambili kwamehlo.
Iimpawu
Iimpawu zeempembelelo zexesha eliqhelekileyo zifana nezo zonyango. Abantu abanokuguguleka kwamanzi ngokuphindaphindiweyo bahlala bekhalaza oku kulandelayo:
- ubuhlungu obukhulu
- unesihlabathi, unesidima esweni kwiso
- uvelwano lokukhanya
- ku qhawula
- obomvu
- Umbono obolileyo
- ukukhanya okungalawulwayo (i-blepharospasm)
Ukuphindaphinda
Ukuphindaphindiweyo kwe-corneal abrasions kunokwenzeka naliphi na ixesha kodwa kaninzi kubakho kwiiveki zokuba zikhuphe ngokuphambili. Abantu bavame ukukhumbula ukuba babe nohlobo oluthile lokuxhatshazwa kwiiveki zangaphambili.
Abantu abahluphekayo ukuguguleka kokuphindaphindiweyo bavame ukufumana iimpawu zabo kusasa xa bevuka kuqala. Iso lisoloko elomileyo elingahlali kulo. Olu lomeko lenza iso linyame kangangokuba ijwabu leso lingadonsa iiseli ze-epithelial ebusweni belihlo xa kuqala uvule iliso ekuseni. Abanye abantu abahluphekayo kule migudu banokubakhombisa amaxesha ama-2-3 ngeveki, kwaye abanye bafumana amaxesha ambalwa kuphela ngonyaka. Abanye abantu banokuzifumana ngakumbi ngexesha elithile lonyaka xa isimo sezulu sitshintsha.
Ukuxilongwa
Ugqirha lakho kwamehlo liyakwazi ukuxilonga ukuguguleka komzimba ngokuphindaphindiweyo emva kokuthatha imbali echanekileyo.
Ukulimala kwangoko kwiso ngento ebukhali kuya kubonakala kutyhilwa. Unokuba ukhononda ngeengqungquthela zentlungu kunye nobubele bokukhanya obubonakala buzayo.
Ubuninzi bakho obubonakalayo buya kulinganiswa. Ugqirha wakho uya kuqhuba idayi ekhethekileyo ebizwa ngokuba yi-fluorescein. Iindawo ezincinci ziso ziza kucoca idayi, zenze i-erosions ibonakale ekukhanyeni i-cobalt eluhlaza okwesibhakabhaka kwiso lakho.
Unyango
Unyango lunokuquka ukuthoba iso nge- cycloplegic yehla . I-cycloplegic iso lihlahla okwesikhashana umfutho we-spasming ngaphakathi kweso elenza intlungu. Ngenxa yokuba iimeko eziphindaphindiweyo zifana namanxeba avulekileyo, banokusulelwa.
I-antibiotics inokumiselwa ukuba usemngciphekweni wokuphuhlisa isifo. Kwezinye iimeko, i-lens ye-bandage yoqhagamshelwano iya kufakwa kwi-cornea iintsuku ezimbalwa okanye iiveki ezimbalwa. Le bhanki ifana ne-Band-Aid, ukugcina izinto zangaphandle kunye nokukhusela i-cornea kwi-eyelid ukuxubha ngokuchasene neziphumo. Ugqirha wakho unokucela ukuba ubuyele rhoqo okokuqala ukuze uqinisekise ukuba iimeko eziphilisayo ziphilisa kwaye zingenasifo.
Thintelo
Iinyembezi zomsebenzi ezinikezwa ngamaxesha amaninzi ngosuku ziya kugcina iso lakho limanzi kwaye liqinisekise impilo yeeseli ze-epithelial. Amagcoba ejoka anokumiselwa ngexesha lokulala. Ngenxa yokuba iliso lakho linomile xa ulala, i-ointments inikezelwa ukubonelela umkhuni ukuze xa uvuka ekuseni, ijwabu leso lingafaki kwi-cornea yakho. Ukulala ngesigxina sejinga kunokugcina umoya ongafunekiyo kwiifenki zelityha ukusuka ekubanjeni iso lakho ebusuku. Ijoni elidlulileyo lihla (iMro 128) linokumiselwa ngethemba lokuba usebenzise i-corneal fluid engaphezulu ukugcina i-cornea eqinile kwaye idibeneyo. Inqubo ebizwa ngokuthi i-stroke stromal puncture ingenziwa, apho ugqirha esebenzisa uhlobo lwenaliti yokuvuthwa ukwenza iiplctures ezincinci kwi-cornea ukudala indawo apho iiseli ze-epithelial zibopha ngakumbi.
I-phototherapeutic keratectomy (PTK) yinye inyango enokwenzeka, apho i-laser isetyenziswe kwisitye se Bowman, esenza ukuba izicubu zibophe ngokuqinileyo kwiiseli ze-epithelial. Oku kungenziwa xa unyango lwangaphambili luphela.
