Panguva imwecheteyo, kutanga kwechirwere ichi hachisi nguva dzose chakajeka, zviratidzo "zvakasvibiswa", uye kuratidzwa kwokutanga kwaro kakawanda kunowedzera zvirwere uye kusina kunaka myopic astigmatism nekuderera kwepamusoro pakuonekwa kwehutano mumamiriro ezvinhu ekugadzirisa zvakakwana nemazamu lenzi. Unhu hunowedzera pakuonekwa kwemaonero kana uchionekwa nemhepo, iyo inoderedza chiedza chinoparadzanisa mazaya uye inotora chikamu chekromia neyunifomu yepfumi inosvika kumhepo. Kugadzirisa zvakanakisisa kururamisa kunoita kuti zvikwanisike kuoma zvakanyanya lens lens, kunyange mumatangi ekutanga nezvo izvi zvinogona kutora kunyange zvakanyanya kutonhora zvakanaka lenzi. Dzidza zvakawanda nezvechirwere ichi muchikamu chinoti "Nhoroondo yechirwere muhuputirairo keratoconus."
Chimwe chinhu chinokosha chinosiyanisa chirwere ichi chimiro chayo uye kufambira mberi kwekupedzisira kupfuura "chikoro" myopia, zera uye kusagadziriswa kwemaziso maviri nekukurumidza kukurumidza kweanisometropia. Zvinyunyuta zveAsphenopic zvine chokuita nekuwedzera kwezvinodiwa zvekushanda kwezvigadzirwa zvekugara zvinowanzoitawo nekuda kwekuonekwa kweastigmatism nekusiyana kwemaziso. Zviratidzo zvinotsanangurwa zvinoita kuti zvikwanise kufungidzira kuburitsa keratoconus uye kushanda sechiratidzo chekutenda ophthalmometry (kana keratometry) uye biomicroscopy pasi pechigadziko chemagetsi. Ne ophthalmometry, kucherechedza kunokonzerwa nekusavhiringidza uye kuderera kwehuwandu hwematanho ekuyera, ruzivo rwekuputika kwe-cornea kusvika kune manomwe uye pasi pema millimeters, kuwedzera kwemasimba ayo okudzivisa kusvika 48 Dpt nezvimwe. Biomicroscopy pamwe nekushandiswa kwechikamu chinopenya chemafuta chinoratidza chimiro chekuenderera mberi kwekoraa, kazhinji kusvika pasi, dzimwe nguva paracentral. Mucheka unowedzera kukurumidza kupera munzvimbo yekeratoconus ine chimiro chekutambisa epithelium, iyo, panzvimbo yekutanga, inotarisana nekukanganisa uye kuparara kweBoorman shell. Zvadaro kune zvikanganiso uye mapepa e stroma uye shell yaDescemet nekuumbwa kwechimiro chaicho-streaks yaVogt. Kushandurwa kwehuwandu hwemashure emakornea zvinongotungamirira kunzvimbo yekurasikirwa kwemasero endothelial uye kupinda mukati pemvura inonaya mu cornea. Semugumisiro, inoratidzika semakango kubva kune imwe nzvimbo kusvika kuhutema rose, iyo inonzi dropsy ye cornea kana acer keratoconus.
Pasinei nehuwandu hwemafungiro pamusoro pehutano hwechirwere mune ophthalmology, chikonzero chekusimudzira keratoconus hachisi pachena. Saka, chirwere chepathogenetic hachipo. Pazvikamu zvekutanga, kutsigira dystrophic therapy kunoitwa nekugadzwa kwe taufon, derinata, mavhisikiji ekugadzirira kurwisana nemamiriro ekururamisa nemaoko akaoma. Kubudirira kwechirwere keratoconus chiratidzo chekuguma-kumagumo keratoplasty. Munguva pfupi yapfuura, vanachiremba vanokurudzira muzvikamu zvekutanga zve keratoconus kuita basa rakabatanidzwa, kubatanidza excimer laser keratectomy ne phototherapeutic keratectomy, zvichikurudzira "corset" zvinhu zve Bowman shell uye cornea. Zvisinei, kunyange zvazvo zvibereko zvitsva zviri kukurudzira, nzira idzi dzinoramba dzichitsigirwa nenguva.
"Phacogenic" myopia
Nokufananidza uye ophthalmology ne phacogenic glaucoma, iyo inowanzokonzerwa nehutachiona, kupfupa, lysis kana subluxation ye lens, zvakakosha kuti iparadzanise uye mecopenous myopia. Muhupenyu, tinosangana nekusiyana uku uye nhoroondo yechirwere kakawanda kupfuura zvainoratidzika. Chero ani zvake ophtalmologist anoziva kuti vanhu vane chirwere vanogona kuona nemairasi asina kunaka. Uye kazhinji vanhu ava vakanga vasina kunyanya kuona mumajaya avo. Chikonzero chekuwedzera kukanganiswa kunogona kuva hydration, hydration, kupera kwemajeni muitiro wekusimudzira cataract. Chinonyanya kuchinja simba rayo rekushandura, kana izvi zvinogadzirisa chikamu chikuru uye chakanyanyisa-chikamu. Nokudaro, zvinokonzera nyukliya zvinowanzotanga nekuonekwa kana kuwedzera kwechirwere. Vamwe vanhu vanotozvirumbidza kuti chiremba anonyora zvisingakwanisi kuverenga magirasi, uye vanogona kutora kare vasina magirasi zvachose. Vamwe vanouya kuna chiremba nemakosveti ekusaona kwemaonero, kazhinji ziso rimwe chete. Chiremba anotora magirazi uye anovimbisa munhu kuti hapana chakaipa, kungova nemakore makumi mashanu nemakumi matanhatu-murume akwegura uye ari kufambira mberi myopia. Pane zviitiko apo, panguva yekuchinja kwegirasi munguva pfupi yegore, zvishoma nezvishoma kufambira mberi (by 2-4pts!) Zvirwere zvakaonekwa kuti uye scleroplasty yakakurudzirwa! Zvechokwadi, nekuuya kwekunyora kwekombiyuta kwevanhu, isu tava kutanga kutarisana, kwekutanga, kuwedzera kwekuregererwa kune vanhu kunyange vakwegura kudarika makore 35-40 avo vari kuita basa rakaoma riri pedyo nepakati. Uye zvakadaro haisi kuitika. Nokudaro, chero kuwedzera kwe keratoconus mugore rechishanu kusvika kwechitanhatu uye makore anopfuura gumi, kunyanya kana segorosi isina kugadziriswa inoderedza maonero ekuona zviri pachena chikonzero chekufungidzira kukura kwehutachiona uye kutungamira kuongororwa kwezvinyorwa. Panosimbisa kuti chirwere checataract uye phacogenic keratoconus, chirongwa chinowanzoitwa mavitamini therapy chinoratidzwa netsanangudzo kumunhu pamusoro pezvikonzero zvinokurudzira myopia. Iye zvino tinoziva kuti nhoroondo yechirwere ichi iripo mune ophthalmology keratoconus.
