Bhuku keratopathy chirwere chinokanganisa cornea , yakajeka dome-soro yakagadziriswa pamucheto uri mberi kweziso. Bato keratopathy inoratidzika neboka rinokwana re calcium rinowanikwa mumakorome.
Iko kunotaridzika kunenge kuchena uye kuchena-grey muvara uye kunotarisa zvishoma se swiss-cheese. Iyo calcium inowanikwa mu-cornea pakati penharaunda yakazaruka uye yakasununguka pakati pemakumbo emaziso apo ziso riri munzvimbo yakazaruka.
Zvinokonzera
Bato keratopathy inofungidzirwa kuti inokonzerwa kubva mumamiriro ezvinhu anowedzera maitiro e calcium mumuviri akadai sehosha yepvo, mavitamini D akawandisa, kuwedzera kwemahymoni ehutachiona, sarcoidosis, lupus uye chirwere chePaget, mamiriro ezvinhu apo kune kuparara kwakanyanya kwe mafupa.
Misodzi ine zvinyorwa zvishoma zve calcium. Kazhinji kubuda kwemisodzi yako kunokonzera kuwedzera kwekamisium. Izvi zvinowanzoitika mune chikamu chekonoa iyo yakazarurirwa kumhepo. Zvisinei, apo misodzi ine yepamusoro-soro pane yakarongeka yemakisikiti, izvi zvinowanzoitika zvikuru. Pamusana pekunyorwa kusina kuchena kwemisodzi, asidi yepamusoro yemisodzi inoshandura inokonzera kuti chirongwa chiitike nekukurumidzira, zvichikonzera band keratopathy. Zvimwe zvirwere zvataurwa pamusoro apa zvinokonzera kuti calcium iwedzere mumuviri inogona kuita kuti izvi zviitike. Zvisinei, calcium inogonawo kuvaka mumisodzi nemamiriro eziso anokonzera kusuruvara kusingaperi.
Uyewo, vanhu vane mamiriro ezvinhu anokonzera kubatwa kwekromaa kana kuora mwoyo kwemasero e-corneal ave achizivikanwa kuti awedzere band keratopathy.
Maziso eziso anokonzera kusaputika kusingaperi zvinogona kukonzera band keratopathy kukura:
- kwenguva refu kana kuguma-gadziriro glaucoma
- chronic iritis (uveitis)
- corneal dystrophies
- phthisis bulbi (shrunken, kwete-kushanda maziso kubva pachirwere chakakomba kana kushungurudzika)
- juvenile arthritis
Imwe inogonawo kubudiswa pane zvimwe zvinhu kunze kwekunze izvo zvinogona, nekufamba kwenguva, zvinokonzera band keratopathy. Kugara kwenguva refu kune mercury vapors vave vachizivikanwa kuti vanokonzera band keratopathy. Uyewo, zvigadziri zvine mercury type svondo zvakawanikwa mune dzimwe mishonga ye ophthalmic.
Zviratidzo
I-calcium deposits inogona kunge yakaoma. Dzimwe nguva, vanogona kuputsa uye vanokonzera marwadzo uye marwadzo pamusoro peziso. Zvimwe zviratidzo ndezvi:
- chiratidzo chakasvibiswa kana chechidiki
- sandy or gritty sensation muziso
- kubwinya
- kutsamwa
Kurapa
Bato keratopathy kurapwa ine chekemikari inonzi chelation. Chiziviso chimiro chemakemikari inoshandisa EDTA (ethylenediamine-tetraacetic acid) iyo chemicho inobvisa calcium kubva ku cornea. Mushure mokupedza chelation, kazhinji kese laser, iyo yakafanana neyo inoshandiswa kuLASIK, inoshandiswa kubvisa chero imwe yakasara yekisiki uye kubvisa pasi kunze.
Mushure mekugadzirisa, kana amniotic membrane kana bandage yekutengesa lens rinoshandiswa kune ziso kwemavhiki mashoma. Kuongororwa kweRopa kunogona kushandiswa kuti uone chinonyatsokonzera band keratopathy kana kuti ichadzoka zvakare.
