Keratoscopy, inonziwo corneal topography kana corneal topography, bvunzo ye ophthalmological inoshandiswa zvakanyanya mukuongororwa kwe keratoconus, inova chirwere chinodzikira chinoonekwa nekushanduka kwemakona, icho chinopedzisira chawana chimiro chekoni, nekunetseka kuona uye nekunzwisisa kukuru kwechiedza.

Kuongorora uku kuri nyore, kunoitwa muhofisi yemaziso uye kunosanganisira kuitisa mepu yekornea, inova nyama yakajeka iri pamberi peziso, ichiratidza chero shanduko muchimiro ichi. Mhedzisiro yeiyo corneal topography inogona kuratidzwa nachiremba mushure mekuongororwa.

Kunyangwe ichinyanya kushandiswa mukuongororwa kwekeratoconus, keratoscopy inoitwawo zvakanyanya munguva yekutanga neyekuvhiya kwekuvhiya kwemaziso, zvichiratidza kana munhu wacho achigona kuita maitiro uye kana maitiro acho aine mhedzisiro inotarisirwa.

Chii ichochi

Corneal topography inoitwa kuti itaridze shanduko mu corneal pamusoro, ichiitirwa kunyanya kune:

• Edza ukobvu uye kukamonana kwekonora;
• Kuongororwa kwekeratoconus;
• Kuzivikanwa kwe astigmatism uye myopia;
• Ongorora kuchinjika kweziso kune iro lens rekubata;
• Tarisa uone corneal degeneration.

Pamusoro pezvo, keratoscopy inzira inoitwa zvakawandisa munguva yekuvhiya kwekuvhiya, kunova kuvhiya kunovavarira kugadzirisa shanduko mukufamba kwechiedza, zvisinei havazi vese vanhu vane shanduko mukonora vanokwanisa kuita maitiro. sezvazvakaita nevanhu vane keratoconus, nekuti nekuda kwechimiro chekonora, ivo havakwanise kuita rudzi urwu rwekuvhiya.

Naizvozvo, kana iri keratoconus, ophthalmologist inogona kukurudzira kushandiswa kwemagirazi ekurapa uye mamwe malensi ekubatana uye, zvichienderana nedanho rekuchinja mukonora, inogona kuratidza mashandiro eimwe nzira dzekuvhiya. Nzwisisa kuti kurapwa kwekeratoconus kunoitwa sei.

Corneal topography inogona kuitwawo mushure menguva yekushanda, zvichikosha kuona kana shanduko yakagadziriswa uye chinokonzeresa kuona kwakashata mushure mekuvhiyiwa kwekuratidzira.

Zvinoitwa sei

Keratoscopy maitiro akapusa, anoitwa muhofisi yemaziso uye inogara pakati pemaminitsi mashanu kusvika gumi nemashanu. Kuti uite bvunzo iyi hazvidi kuti kuve nekuwedzeredzwa kwemudzidzi, nekuti hakuzoongororwa, uye zvinogona kukurudzirwa kuti munhu wacho asapfeke malenzi ekuonana mazuva maviri kusvika manomwe bvunzo usati waitwa, asi kurudziro iyi zvinoenderana kutarisisa kwechiremba uye iyo lenzi yemhando yakashandiswa.

Kuti aite bvunzo, munhu wacho akamira mune chishandiso chinoratidza maringi akati wandei echiedza, anozivikanwa semhete dzePlacido. Iyo cornea ndiyo chimiro cheziso rinotungamira kupinda kwechiedza uye, nekudaro, zvinoenderana nehuwandu hwechiedza chinoratidzirwa, zvinokwanisika kutarisa kupindika kwekona uye kuona shanduko.

Daro pakati pemaringi emwenje anoratidzwa rinoyerwa uye kuongororwa nesoftware pakombuta inoenderana nemidziyo. Ruzivo rwese rwunowanikwa kubva mukubuda kwemaringi emwenje anotorwa nechirongwa uye oshandurwa kuita mepu yemuvara, iyo inofanirwa kududzirwa nachiremba. Kubva pane iwo mavara aripo, chiremba anogona kutarisa shanduko:

• Tsvuku uye orenji zvinoratidza kukombama kukuru;
• Bhuruu, violet uye girini zvinoratidza zvakapfava curvature.

Nekudaro, iyo yakanyanya kutsvuka uye orenji mepu, inowedzera shanduko mukonora, zvichiratidza kuti zvakakosha kuita mimwe bvunzo kupedzisa kuongororwa uye kutanga kurapwa kwakakodzera.
