Zowawa Pambuyo Kuvulala
Kutha kwa nthaka kwatsopano kumakhala kutseguka kapena kuwonongeka kwa maselo okhala pamwamba pa cornea . Maselo omwe amapanga pamwamba pa cornea amatchedwa maselo a epithelial. Maselo a epithelial awa amamangidwa mwamphamvu ku cornea ndi wosanjikiza pansi, wotchedwa wosanjikiza wa Bowman. Chingwe cha Bowman chimagwira ntchito ngati glue kuti agwirire maselo achilendo mwamphamvu.
Chombo cha Bowman ndi chopangidwa ndi collagen. Pamene chinsaluchi chawonongeka kapena chosachiritsika, mndandanda wapamwamba wa maselo a epithelial amalephera kuchiritsa bwino ndipo sungamangirire molondola kwa wosanjikiza wa Bowman. Zotsatira zake, maselo achilendo amachokera mosavuta. Ma cell epithelial regenerate koma amalembedwa bwino mpaka wosanjikiza wa Bowman. Nthaŵi ndi nthawi, maselo a epithelial amagwa mosavuta, akusiya zilonda zosaoneka ngati zowonongeka kapena kupuma pamaso.
Zowopsa
Kutha kwa nthaka komwe kumachitika nthawi zambiri kumayambitsa kuvulazidwa koyambirira kwa chingwe cha cornea ndi Bowman. Ngati muvulaza diso lanu ndi chida chakuthwa kapena chovala chachingwe kapena mutenge pepala lodula pamaso lomwe limapangitsa kuti thupi lanu lisasokonezeke, muli pangozi yoti mutha kukulirakulira.
Anthu omwe amadwala matenda enaake otchedwa dystrophies (epithelial submbrane dystrophy (EBMD), reis-Bucklers dystrophy, lattice dystrophy, granular dystrophy, Fuch's endothelial dystrophy) angakhalenso ndi zochitika zowonongeka.
Mwa anthuwa, mbali ya kutsogolo kapena yamkati ya cornea ikhoza kukhala matenda, zomwe zimayambitsa maselo apakati kuti asamangidwe mwamphamvu ku cornea. Nthawi zina amatha kutaya nthawi, koma ngati anthu omwe ali ndi kachilombo ka pansi pamtunda amayamba kukumana ndi vutoli, amakhala ndi chiopsezo chachikulu chokhalira ndi mavuto omwe amayamba nthawi yayitali pamoyo wawo.
Anthu omwe akudwala matenda owuma amatha kukhala ndi chiopsezo chachikulu chokhalira ndi mavuto omwe amachititsa ngati akuwonongeka maso.
Zizindikiro
Zizindikiro za zochitika zowonongeka zowonongeka zimakhala zofanana ndi za kutupa kwa thupi. Anthu omwe ali ndi kutukuka kwa nthaka kumakhala akudandaula ndi zotsatirazi:
- ululu wopweteka
- mchenga, kumverera kokongola mu diso
- kutulutsa kuwala
- kudula
- zofiira
- masomphenya olakwika
- kuzimitsa kosasintha (blepharospasm)
Kubwereza
Zowonongeka zamtundu wa abrasions zikhoza kuchitika nthawi iliyonse koma nthawi zambiri zimachitika mkati mwa masabata kuti zikhale zoyamba kubisala. Anthu amakonda kukumbukira kuti anali ndi vuto linalake ku masabata oyamba.
Anthu omwe akuvutika ndi kutuluka kwa nthaka mobwerezabwereza amakhala ndi zizindikilo m'mawawu atadzuka. Diso nthawi zambiri limauma pang'ono kuchokera ku tulo. Kuuma kumeneku kumapangitsa diso kukhala lolimba kwambiri kuti khungu likachotseko maselo achilendo kuchokera pamwamba pa diso pamene poyamba mutsegula diso m'mawa. Anthu ena omwe amavutika ndi mavutowa akhoza kukhala nawo 2-3 pa sabata, ndipo ena amawawona kangapo pachaka. Anthu ena amawawona nthawi zambiri pa nthawi imene nyengo imasintha.
Kudziwa
Dokotala wanu amatha kuona kuti kutentha kwa thupi kumakhala kosavuta mutatha kutenga mbiri yosamala.
Kuvulazidwa kwaposachedwa kwa diso ndi chinthu chakuthwa nthawi zambiri kudzawululidwa. Mwinamwake mukudandaula za zizindikiro za ululu ndi mphamvu zowala zomwe zikuwoneka zikubwera ndi kupita.
Zomwe mumaonera zikuyendera. Dokotala wanu adzapangira tebulo lapadera lotchedwa fluorescein. Dera laling'ono la diso lidzakuta utoto, kupanga zokopa zikuwonekera powwala kuwala kwa buluu kumaso ako.
Chithandizo
Kuchiza kungaphatikizepo kuchepetsa diso ndi madontho a maso a cycloplegic . Diso la Cycloplegic limadumpha kwa kanthawi kochepa kupweteka kwa minofu mkati mwa diso lomwe limapweteka. Chifukwa chakuti zowonongeka mobwerezabwereza zili ngati mabala otseguka, akhoza kutenga kachilomboka.
Mankhwala opha tizilombo angapangidwe ngati muli pachiopsezo chotenga matenda. Nthaŵi zina, makina ojambulira amanjenje adzagwiritsidwa ntchito ku cornea kwa masiku angapo kapena masabata angapo. Bandage iyi imakhala ngati Band-Aid, kuteteza zinthu zakunja ndikuziteteza ku cornea kuchoka pa khungu la chikopa. Dokotala wanu akhoza kukupemphani kuti mubwerere kawirikawiri poyamba kuti muwonetsetse kuti zovuta zikuchiritsidwa komanso kuti zisatengeke.
Kupewa
Misozi yowonjezera imaperekedwa kangapo patsiku, imapangitsa kuti diso lanu likhale lonyowa komanso kuonetsetsa kuti maselo achilendo amatha kukhala ndi thanzi labwino. Mafuta a maola angapangidwe pa nthawi yogona. Chifukwa chakuti diso lanu likhoza kuyanika pamene mukugona, mafuta operekedwa amapereka kanyumba kotero kuti mukadzuka m'mawa, chikopa chanu sichimamatira ku cornea yanu. Kugona ndi chigamba cha diso kungapangitse mpweya wosafuna kuchokera kumapiri a denga kuti usayese maso ako usiku. Matope a diso (Muro 128) angapangidwe kuti akhale ndi chiyembekezo chofuna kuchotsa madzi ochulukirapo kuti asamangidwe bwino. Njira yotchedwa antiter stromal puncture ingagwiritsidwe ntchito, kumene dokotala amagwiritsa ntchito mtundu wa singano yopanga opaleshoni kuti apangire punctures zing'onozing'ono mu cornea kuti apange dera limene maselo achilendo amamanga kwambiri mwamphamvu.
Phototherapeutic keratectomy (PTK) ndi mankhwala ena omwe angatheke, momwe laser imagwiritsidwa ntchito pa wosanjikiza wa Bowman, zomwe zimapangitsa kuti minofuyo imangirire mwamphamvu kwambiri ku maselo a epithelial. Izi zikhoza kuchitika pamene mankhwala ambuyomu alephera.
