Ubuhlungu Ngemva Kokulimala
Ukuguguleka komzimba okuqhubekayo ukuvulwa noma ukuphazamiseka okwejwayelekile kwamaseli asendleleni engenhla ye- cornea . Amaseli akha i-layer ephezulu ye-cornea abizwa ngamaseli e-epithelial. Lawa maseli e-epithelial ahlanganiswe ngokuqinile ku-cornea ngendlala engaphansi, ebizwa ngokuthi ungqimba lukaB Bowman. Uhlaka lwe-Bowman lusebenza njengeglue ukubamba amaseli e-epithelial ngokuqinile esweni.
Isendlalelo se-Bowman senziwe nge-collagen. Uma lo ungqimba ubonakalisiwe noma unempilo, ungqimba oluphezulu lwamaseli e-epithelial alukwazi ukuphulukisa kahle futhi ungalokothi lubophe ngokufanele kocingo luka Bowman. Ngenxa yalokho, amaseli e-epithelial aphuma kalula. Amaseli e-Epithelial avuselela kodwa ahlanganiswa kahle ekubhekeni kocingo luka Bowman. Ngezinye izikhathi, amangqamuzana e-epithelial azowa kalula, ashiye isifo esivulekile esifana nokuqala noma ukuphazamiseka emehlweni.
Izingozi Zezingozi
Ukuguguleka komzimba okuvamile okuvamile kubangelwa ukulimala kwangaphambilini kwendlalelo ye-cornea no-Bowman. Uma ulimaza iso lakho ngethuluzi elibukhali noma umunwe noma uhlushwa iphepha elibhekene ne-eye eliholela ekuqothulweni kwe-corneal, usengozini yokuthuthukisa ukuguguleka komzimba okuqhubekayo.
Abantu abanezinkinga ezithile ze-dystrophies (corithelal sub-membrane dystrophy (EBMD), i-Reis-Bucklers dystrophy, i-lattice dystrophy, i-dystrophy e-granular, i-Fuch's endothelial dystrophy) ingabuye ibe nezinkinga eziphindaphindiwe.
Kulaba bantu, ingxenye yangaphambili noma yangaphakathi ye-cornea ingaba nesifo, okwenza amangqamuzana e-epithelial angazibopheli ngokuqinile ku-cornea. Ngezinye izikhathi bangathola ukuguguleka kwamanye amazwe kodwa uma abantu abanegciwane lesandulela ngendwangu elingaphansi bebhekene nesibindi, bangengozini enkulu kakhulu yokuthuthukisa izimo eziphuthumayo eziqhubekayo ekuphileni kwesikhathi eside.
Labo ababhekene ne- eye eye syndrome bangase babe engozini enkulu yokuthuthukisa ukuguquka kokuphindaphindiwe uma bebona ukulimala kwangaphambili kwamehlo.
Izimpawu
Izimpawu zemizamo yokuphindaphindiwe ye-corneal zifana nalezo zokukhishwa kwamagciwane. Abantu abanokuvuthwa kwe-corneal okuphindaphindiwe bavame ukukhononda ngalokhu okulandelayo:
- ubuhlungu obunzima
- unesihlabathi, unomusa osesweni
- ukuzwela okukhanya
- ukudubula
- ubomvu
- umbono ongenalutho
- ukukhanya okungalawuleki (i-blepharospasm)
Ukuphindaphindiwe
Amaphutha okuphindaphinda avamile angenzeka nganoma yisiphi isikhathi kodwa ngokuvamile ayenzeka phakathi kwamasonto okuba ne-primary corneal abrasion. Abantu bavame ukukhumbula ukuthi babe nohlobo oluthile lokuhlukunyezwa emavikini amaso ngaphambili.
Abantu ababhekene nokuguguleka okuphindaphindiwe bavame ukuzwa izimpawu zabo ekuseni lapho bevuka kuqala. Iso ngokuvamile liyomile kancane ekulaleni. Lokhu kumile kwenza iso linyameke ngakho ijwabu leso lingadonsela amangqamuzana e-epithelial ebusweni baso uma kuqala uvula iso ekuseni. Abanye abantu ababhekana nalezi zinkinga bangaba nezikhathi ezingu-2-3 ngesonto, futhi abanye bazibonela izikhathi ezimbalwa ngonyaka. Abanye abantu bangase bazibonele kakhulu ngezikhathi ezithile zonyaka lapho isimo sezulu sishintsha.
Ukuxilongwa
Udokotela wakho wezilanga angase ahlolisise ukuguguleka komzimba okuqhubekayo ngemuva kokuthatha umlando oqaphele.
Ukulimala kwamuva kweso ngento ebukhali kuzovulwa. Ungase ukhononde ngeziqephu zobuhlungu nokuzwela okukhanya okubonakala kubonakala futhi kuhamba.
I- acuity yakho ebonakalayo izokala . Udokotela wakho uzobe esefaka idayi ekhethekile ephuzi ebizwa ngokuthi i-fluorescein. Izindawo ezincane zeso zizocwilisa idayi, okwenza ukuguqulwa kwemibono kubonakale ekukhanyeni ukukhanya okuluhlaza okwesibhakabhaka ebusweni lakho.
Ukwelapha
Ukwelashwa kungase kuhlanganise nokuthobisa iso ngehla le-cycloplegic . I-cycloplegic iso lehla kancane okwesikhashana umfutho we-spasming ngaphakathi kweso elidala ubuhlungu. Ngenxa yokuthi ukukhulelwa okuvamile kufana namanxeba avulekile, angenwa igciwane.
Ama-antibiotic angase abekwe uma usengozini yokuthuthukisa isifo. Kwezinye izimo, i-lens yokuxhumana ye-bandage izosetshenziselwa i-cornea izinsuku ezimbalwa noma amasonto ambalwa. Le-bandage yenza njenge-Band-Aid, igcina izinto zangaphandle futhi ivikela i-cornea kusukela ejwayele i-eyisikili ukuxubha ngokumelene nezinkinga. Udokotela wakho angakucela ukuthi ubuyele njalo ekuqaleni ukuze uqiniseke ukuthi ukukhulelwa kuyaphulukisa futhi kungenasifo.
Ukuvimbela
Izinyembezi zokufakelwa ezinikezwa izikhathi eziningi ngosuku zizogcina iso lakho limanzi futhi liqinisekise impilo yezingqamuzana ze-epithelial. Amafutha okugcoba ama-Eye angahle anqunywe ngesikhathi sokulala. Ngenxa yokuthi iso lakho lingase lime ngenkathi lilele, amafutha okugcoba anikezwa ukuhlinzeka isikhwama ukuze kuthi uma uvuka ekuseni, ijwabu leso lakho alinamathele ku-cornea yakho. Ukulala nge-punch ye-eye kungagcina umoya ongafuneki kubalandeli be-plailing kusuka ekungeneni iso lakho ebusuku. Amaconsi ama iso (uMu 128) angahle anqunywe ngamathemba okukhipha i-corneal fluid ngokweqile ukugcina izingxenye ze-cornea ziqinile futhi zihlangene. Inqubo ebizwa ngokuthi i-anterior stromal puncture ingenziwa, lapho udokotela esebenzisa khona inaliti yokuhlinza ukudala ama-punctures amancane ku-cornea ukudala indawo lapho amaseli e-epithelial azobopha ngokuqinile.
I-keratectomy ye-phototherapeutic (PTK) ingenye ukwelashwa okungenzeka, lapho isilazi isetshenziswa khona ungqimba luka Bowman, okwenza izicubu zibophe ngokuqinile ngokwengeziwe kumaseli e-epithelial. Lokhu kungenziwa uma ukwelashwa kwangaphambilini kwehluleka.
