Keratoconus chirwere chinokonzera kuti cornea ibude kunze. Iyo cornea ndiyo yakajeka, dome-yakafanana sarudzo pamucheto wekutanga weziso. Nokufamba kwenguva, iyo cornea inowedzera uye yakasimba. Keratoconus ishoko rechiGiriki rinoreva "kone-shaped cornea." Nemamiriro acho ezvinhu, the cornea inova yakafanana, uye chiratidzo chinonyangadza zvakanyanya uye chinosvibiswa.
Keratoconus inotanga kutanga kuratidzira mumakore ekuyaruka uye inopera shure mushure mezera remakore makumi mana. Vanhu vangave vasingazivi kunyange kuti vane izvozvo pakutanga. Kunyange zvazvo keratoconus inoratidzika kunge yakaipa mune rimwe ziso, inowanzova mamiriro ezvinhu anowanikwa mumaziso ose. Apo keratoconus inofambira mberi, zviratidzo zvinosviba zvikuru uye zvinokanganisa. Chiono chinonyanya kuwedzera nokuti sezvo cornea bulges mberi, zvisina kufanira astigmatism uye kutarisa mberi kunowedzera. Sezvo mamiriro acho ezvinhu achifambira mberi, kuora kwekona kunogona kuitika, zvichiita kuti kuve nekuona kurasikirwa. Vamwe varwere vane keratoconus vanocherechedza maonero achigadzikana kakawanda apo vamwe chete vanoona kuchinja kwemakore emakore.
Vanhu vane keratoconus vanowanzopopotera kuti chiratidzo hachina kubudirira zvikuru nemakiromesi emaziso. Mune zvimwe zviitiko, the cornea inogona kukurira mberi uye yakaoma kwazvo zvokuti kushayikwa kunowedzera, nekuwedzera kuisa pfungwa. Muzviitiko zvisingawanzoitiki, iyo cornea inogona kukanganisa, zvichiita kuti zvishoma nezvishoma zviratidzo kana kuti kupofu.
Zvinokonzera Keratoconus
Chikonzero chaicho che keratoconus chinhu chiduku chechakavanzika. Zvisinei, masayendisiti anotenda kuti genetics, nzvimbo, uye mahomoni zvinogona kukonzera nei vamwe vanhu vachiita keratoconus.
Genetics: Inofungidzirwa kuti vamwe vanhu vane chiremera chema genetic chinokonzera kuti mapuroteni emuviri muornea ave vasina simba.
Izvi zvinoshandisa kubata cornea pamwe chete ichichengetedza chimiro chayo chakajeka, chakafanana. Apo mafivha aya anoshayiwa simba, iyo cornea inotanga kukura mberi. Vamwe masayendisiti vanodavira kuti genetics inobatsira zvikuru mu keratoconus nokuti, pane dzimwe nguva, hama inenge ichiwedzerawo keratoconus.
Zvakatipoteredza: Vanhu vane keratoconus vanowanzova nemakumbo ose, kunyanya pane zvirwere zvinokonzera zvirwere zvakadai sefuru fever , chirwere chemafi, eczema, uye kudya kwekudya. Zvinofadza kuti varwere vazhinji vanoita keratoconus vane nhoroondo yekushongedzwa kweziso. Vamwe vevanhu ava vane mishonga uye vamwe havaiti, asi vanowanzochera maziso avo. Zvinofungidzirwa kuti ziso iri rakasimba rinokuvadza rinogona kukanganisa kukora, zvichiita kuti keratoconus ikure. Imwe yedzidziso yakakurumbira pamusoro pezvinoita kuti keratoconus isakanganise mupfungwa. Nokuda kwechimwe chikonzero, vanhu vanokura keratoconus vane kuderera kweva antioxidants mukati mekonoa. Apo cornea isina antioxyidants yakakwana, collagen mukati mekonoa inoshaya simba uye cornea inotanga kuwedzera. Kushushikana mupfungwa kunogona kukonzerwa nemagetsi zvakadai sekunyora kwemaziso kana mune dzimwe nguva, kuwandisa kwehutachiona hwevivi.
Hormonal dzinokonzera: Nemhaka yezera rekutanga kwe keratoconus, inofungidzirwa kuti mahomoni anogona kuita basa guru mukuvandudzika kwarwo.
Zvakajairika kuti keratoconus ikure mushure mekupera. Izvo zvave zvichiratidzwa kuti zvifambire mberi kana kufambira mberi mumadzimai ane pamuviri.
Kuongororwa kweKeratoconus
Kazhinji kacho, vanhu vane keratoconus yekutanga vanotanga kushandura astigmatism. Astigmatism inokonzerwa ne- cornea ine chimiro chemafuro, sebhola, pane nzvimbo yakafanana, sebhasikiti.
A cornea ine astigmatism ine mazhe maviri, imwe yemapapirovha, uye imwe ine mhepo. Izvi zvinokonzera mifananidzo kuti ione kusvibiswa muwedzere kuoneka kujeka. Zvisinei, varwere ava vanowanzo kudzoka muhofisi yavo yeOptometrist zvishoma nezvishoma, vachigunun'una kuti maonero avo anoita seasina kuchinja.
Nemhaka yekuti cornea zvishoma nezvishoma inowedzera, kutarisa mberi kunowanzoonekwawo. Kutarisa mberi kunoita kuti zvinhu zvive zvisinganzwisisiki kure.
Vanachiremba vemaziso vanoyera kupera kwekonoa ne keratometer. Anogona kuona kuwedzera kwekufamba kwenguva kwenguva, uye kuongororwa kwemaitiro ekurapa kucharairwa. A corneal topographer inzira yekombiyuta yemapupa maitiro uye hurefu hwekonoa. A corneal topographer inobereka mapepa evaravara anoratidza nzvimbo dzakakwirira mumoto wekushisa, mavara matsvuku uye nzvimbo dzakadzika mumvura inotonhora, mavara machena. Nzvimbo yepamusoro inonyanya kuratidzira kuderera kwakanyanya kwekornea. Dzimwe nguva kuongorora kwemaitiro kucharatidzawo kumira kwepakati pakati pechikamu chepamusoro chekonoa nehafu yepasi ye cornea.
Pamwe pamwe nekuongororwa kweziso rakajeka , vanachiremba vemaziso vanozoitawo magetsi ekuongorora magetsi vachishandisa imwe nzira yakarurama yebio-microscope kuti iongorore cornea. Kazhinji kacho, keratoconus varwere vachave nemitsetse yakanaka mumakona avo anonzi Vogt's striae. Uyezve, denderedzwa resimbi rakavhara kumativi e-cornea rinogona kuonekwa.
Mishonga yeKeratoconus
Kune nzira dzakawanda dzokurapa keratoconus zvichienderana nekuoma kwemamiriro acho.
Soft astigmatism contact lens: Mumatambo okutanga e keratoconus, inonzi soft toric lens ingave yakasakara. Inonzi lens lens is lens that corrects astigmatism. Iyo lens iri nyore, asi ine simba maviri: rimwe simba uyewo simba rakasiyana 90 degrees kure.
Gasi yakawanda inokonzerwa nemafungiro emagetsi: Muzvikamu zvisinganzwisisiki zve keratoconus, gasi rakasimba rinogadziriswa lens rinoputika. Rimwe gorosi rinokonzerwa negasi rinogadzirisa nzvimbo yakaoma, kuitira kuti chero kukanganiswa kwegoni kunogona kuvharwa. Sezvo keratoconus inofambira mberi, zvingava zvakaoma kuvhara gasi rakaoma ganda rinokonzerwa nemusero nekuda kwekuwedzerwa kwemaitiro lens nekugadzirisa kwema-lens. Gasi yakawanda gorosi inokwana lenzi yakakura maseroti, kazhinji inotenderera masendimita 8 kusvika ku10 muhupamhi uye inofambisa zvishoma neyeyodhi.
Nhengo dzemajeri ezvibhenekeri: Lenzi rekushongedzanisa rine lenzi yakakura inogadzirwa nemhepo yakasimba yegasi inogadziriswa nejasi rakapoteredza. Izvi zvinopa hutano huri nani kune munhu akapfeka lens. Nokuti nzvimbo yacho yakasimba, inoramba ichipa maonero ekugadziriswa saiyo nguva dzose inogadzika gasi inokwana lens.
Shanduro yekukurukurirana lenzizi: Kukurukurirana kwema-lenses kune makirosi makuru kwazvo ayo anogadzirwa nemashoko akafanana neaini yakaoma gasi rinokwana lenzi yakaitwa. Zvisinei, scleral lens ihuru kwazvo uye inovhara cornea uye inopindirana pamusoro pekatsva, chikamu chitsvene cheziso. A scleral lens zvachose yakazara chikamu chakanyanya che cornea, ichiwedzera kunyaradza nekuderedza mikana yekucheka.
Corneal cross-linking: Corneal cross-linking inzira itsva iyo inoshanda kusimbisa zvisungo mu cornea kuti ibatsire kuchengetedza chimiro chayo. Iyo nzira inosanganisira kushandisa riboflavin (vitamini B) kune ziso mumwero wemvura. Chiedza chechiedza chinoshandiswa kune ziso kuti iwedzere nzira. Corneal cross-linking kazhinji hairi kurapa keratoconus kana kuderedza kuwedzera kwekonoa, asi inodzivirira kuti irege kukura.
Inopisa keratoplasty: Kazhinji, keratoconus inogona kukura kusvika pakakonzerwa nekugadzirisa korneal. Pakati penzira inoputika yekeratoplasty , donor cornea inosungirirwa kune chikamu chepakati chemugadziri wekonoa. Nzira itsva yewaser laser inowedzera kubudirira kwekugadzirwa kwegoni. Kazhinji, kuputika kwegoni kunobudirira. Zvisinei, kuramba iwe nguva dzose kune hanya. Izvo zvakaoma kufanotaura chigumisiro chekupedzisira kwechiono chemu murwere. Kunyange zvazvo kuiswa kwacho kungave kubudirira, murwere angangopedzisira aine mishonga yakakwana uye chidiro chokupfeka magirazi.
