Kuchiza matendawa ndi matenda omwe amakhudza cornea , zomangidwa bwino ngati dome pambali kutsogolo kwa diso. Matendawa amadziwika ndi kashiamu yambiri yomwe imayikidwa pamtunda wa cornea.
Mtunduwu umakhala wonyezimira komanso wofiira mtundu wake ndipo umawoneka ngati swiss-tchizi. Kalisiyamu imayikidwa mu cornea pakati pa dera limene lili lotseguka ndi lodziwika pakati pa maso ake pamene maso ali pamaso.
Zimayambitsa
Matendawa amayamba chifukwa cha zizindikiro zomwe zimapangitsa kuti thupi likhale ndi matenda a impso, mavitamini D owonjezera, mahomoni ambiri a chithokomiro, sarcoidosis, lupus ndi Paget, zomwe zimakhala zoopsa kwambiri. mafupa.
Misozi imakhala ndi kashiamu yochepa. Kutuluka kwadzidzidzi kwa misonzi yanu kumapangitsa kuti kashiamu iwonjezeke. Izi zimachitika kwambiri mu mbali ya cornea yomwe imatsegukira mpweya. Komabe, pamene misonzi ili ndi calcium yamtundu wambiri, izi zimachitika pamlingo waukulu kwambiri. Chifukwa cha mchitidwe wodabwitsa wa misonzi, kuchepa kwa misozi kumapangitsa kuti njirayi ichitike ngakhale mofulumira, zomwe zimapangitsa kuti khungu lisatengedwe. Matenda ena omwe atchulidwa pamwambawa omwe amachititsa kuti kashiamu kuphuke m'thupi, amachititsa kuti izi zichitike. Komabe, calcium ikhoza kumanganso misozi ndi maso omwe amayambitsa kutupa kosatha.
Ndiponso, anthu omwe ali ndi zifukwa zomwe zimayambitsa kutupa kwa cornea kapena kuchepetsedwa kwa maselo okhwima amadziwika kuti akupanga gulu lachilendo.
Maonekedwe a diso omwe amachititsa kuti kutupa kosatha kuchititsenso kuti tizilombo toyambitsa matenda tiyambe:
- glaucoma ya nthawi yaitali kapena yotsiriza
- chronic iritis (uveitis)
- ziphuphu zamakono
- Nthenda ya phthisis (diso la shrunken, losagwira ntchito kuchokera ku matenda aakulu kapena zoopsa)
- mwana wamatenda
Mmodzi angathenso kuwonetsedwa ku zinthu zakunja zina zakunja komwe, pakapita nthawi, zimayambitsa matenda a khungu. Kutsegula kwanthawi yaitali kwa mpweya wa mercury kwadziwika kuti imayambitsa matenda a keratopathy. Komanso, mankhwala osungirako mankhwala omwe amapezeka ndi mercury amapezeka m'ma mankhwala ena ophthalmia.
Zizindikiro
Mankhwala a kashiamu angakhale ochepa kwambiri. Nthaŵi zina, amatha kuchoka ndi kuchititsa ululu ndi zowawa pamaso pa diso. Zizindikiro zina ndi izi:
- masomphenya otupa kapena otsika
- mchenga kapena ubongo m'maso
- zofiira
- kukwiya
Chithandizo
Mankhwala othandizira odwala matendawa ali ndi mankhwala omwe amatchedwa chelation. Chimake ndi mankhwala omwe amagwiritsa ntchito EDTA (ethylenediamine-tetraacetic acid) yomwe imachotsa kashiamu ku cornea. Pambuyo pa chelation, kawirikawiri laser yamakono, yofanana ndi imene amagwiritsidwa ntchito ku LASIK, imagwiritsidwa ntchito kuchotsa kashiamu yotsalayo ndi kuyendetsa kunja.
Pambuyo pa ndondomekoyi, kaya amniotic nembanemba kapena bandage yofewa yothandizana nayo imagwiritsidwa ntchito kwa diso kwa masabata angapo. Mayesero a magazi angafunikire kuchitidwa kuti azindikire chifukwa chenicheni cha bandera matendawa kapena adzakhalanso.
