Pachymetry chirwere chisinganzwisisiki, chinorwadza chinokurumidzira kutarisa kuwanda kwekonoa.
Nei Chichienzanisa Kuora Kwemakoroni?
Corneal thickness sezvakayerwa pachymetry inokosha mundima yekucherechedza kweziso nekuda kwezvikonzero zvakawanda.
Pachymetry inogona kutaurira vanachiremba kana iyo cornea inoputika. Mishonga yakadai seFich's Dystrophy inogona kuwedzera kusviba mumakoria uye kuita kuti kuwedzera kwehuwandu huvepo.
Kunyangwe kupfeka mairi lenzi dzimwe nguva zvinokonzera kukonzera kukuru kwegungwa. Izvi zvingave zvakaoma kuona pasi pe microscope. Zvisinei, pachymetry icharatidza kuwedzera kwakasimba kwehupamhi.
Corneal thickness inonyanya kukosha pakushandura nzira dzekuvhiya dzakadai seLASIK . Zivo ye corneal thickness inokosha kuziva kana munhu ari mukana wokururamisa maziso. Nokuti chikamu chemuitiro wacho chinosanganisira kubvisa mishonga iyo ichasiya muchengeti wekromine, zvinokosha kuti uzive zvakakwana kuti chii chichagara. Vamwe vanhu vangave vane cornea inongova yakaipisisa kupfuura yakasikwa. Izvo hazvikonzeri matambudziko kana zvirwere, asi zvinogona kutarisa kushungurudzika kwekuona kurasikirwa kana nzira yekufuratira inoshandiswa kune mumwe munhu ane konea yakaonda kwazvo.
Pachymetry yakave yakakosha mukuchengetedzwa kwe glaucoma . Glaucoma chirwere umo kushungurudzwa kweziso (intraocular pressure) kunogona kukwidziridzwa.
Kuwedzerwa kwemaziso maziso kunogona kukonzera nerve fibhi kurasikirwa mu retina iyo inogona kuita kuti upofu kana kuti kuderera kwemaonero. Nzira dzakawanda dzinosanganisira nzira yekuenzanisa kushungurudzwa kwameso umo icho chimbo chinobata cornea. Vatsvakurudzi vakaona kuti kuwedzera kwegoni kunogona kusiyanana zvishoma muhuwandu hwevanhu. Corneal thickness inogona kukonzera kuverenga chaiyo kwehuwandu hwekumanikidza muziso.
Uyezve, kujekesa kwepakati corneal thickness sechiratidzo chekuzvidzivirira chengwaru ye glaucoma neOcular Hypertensive Treatment Study (OHTS) yakaita kuti corneal pachymetry chikamu chinokosha chekuedza kwe glaucoma.
Ko pachymetry yakaitwa sei?
Pachymetry inogona kuitwa nenzira mbiri, nemaitiro e ultrasound kana maitiro ekugadzira.
Ultrasound Pachymetry: Ultrasound pachymetry sezvinoreva zita, inoshandisa maitiro e ultrasound kuyera kubwinya kwekonoa. Iyi nzira inoshandisa zviyero zvinodhura zvinobudirira uye zvinoshandiswa. Chinyorwa chikuru chekuyera kwekodeni yakakura ne ultrasound ndechokuti probe inoshandiswa kugunzva cornea inofanirwa kumira zvakakwana. Chero hupi zvishoma kuenderera mberi uye kuverenga kungasave kwakarurama. Imwe yema ultrasound pachymeters yakagadzirirwa zvimwe zvekuongorora kwe glaucoma uye inosanganisira yakavakwa muhutano hunokonzera kuverenga.
Optical Pachymetry: Kubwinya kwepymmeteri kunowirirana pane zvakagadzirwa. Mamwe mapikmeter anopenya akagadzirirwa kuendeswa kune biomicroscope iyo vanachiremba vemaziso vanoshandisa iyo inonzi chiedza chetsvuku. Zvimwe zviyero zvinogona kuongorora pachymetry uchishandisa microscopy inonzi specular. Ichi chigadziro hachizobatana zvakananga ne cornea. Imwe nzira yepymetmetry yakagadzirwa yakawanikwa pakuzivikanwa ndeye OCT kana optical coherence tomography pachymetry.
OCT pachymetry zvakare haibatsiri cornea kuti iite zviyero. OCT inoshandisa mutemo unonzi optical interferometry. Imwe nzira yakakosha yekushandisa kushandisa chimwe chinhu chinonzi Scheimpglug imaging yakanaka kwazvo pakuwana miviri yakawanda yechipfuva ye corneal thickness kuwedzera kusvika pakati pekwenyuka uye kuwana zviyero izvi nekukurumidza zvikuru. Izvozvo zvinokonzerwa nepopymetry yakagadzirwa ndeyekuti makambani einishuwarenzi anowanzobhadhara ultrasound pachymetry uye kwete nguva dzose ye opy pachymetry kuitira kuti zvigoneke kuti chiremba wako angakukumbira kubhadhara.
