Thiab tsis tooj rau qhov pom ntawm qhov muag pom hauv myopic ob lub qhov muag ntawm cov neeg lub qhov muag yog me thiab nrog lub me me voj voos ntawm curvature ntawm cornea. Feem ntau, xws li ib qho kev sib tawg tshwm sim hauv cov neeg txheeb ze tam sim ntawm tus neeg mob, txij thaum feem ntau kis tau los ntawm hom kab mob ntsws. Cov menyuam yaus no yog tus cwj pwm zoo ntawm qhov muag pom tseeb ntawm qhov tsis muaj tsom iav, txawm tias muaj qib high school myopia. Cov lus qhia txog tus kab mob no thiab nws txoj kev loj hlob - nyob rau hauv ib tsab xov xwm ntawm nqe lus "Yuav ua li cas kom tsis txhob muaj cov mob myopia hauv cov menyuam yaus."
Feem ntau, cov niam txiv them nqi rau qhov tseeb tias tus me nyuam ntsia cov duab los yog cov khoom ua si, ze ze rau lawv qhov muag, thiab qhov no yog vim qhov ntawm qhov kev taw qhia ntxiv ntawm qhov pom tseeb. Ntawm lub fundus, raws li txoj cai, tsis muaj cov cwj pwm cov xeeb ceem ntawm cov lus qhia ntawm lub qhov muag - lub myopic crescent, lub khob hliav qab ntawm lub vas sab ntawm cov hlab ntsha ntawm optic paj los yog lub staphyloma ncig nws. Yog tsis muaj kev ntxhov siab ntawm lub qhov muag ntawm lub qhov muag, thaum loj choroidal vessels pom los ntawm lub ncav txheej ntawm cov xim epithelium. Tsis tas li ntawd, tsis muaj cov tsos mob ntawm tus mob iopia nrog cov kev hloov hauv cheeb tsam thaj chaw, thinning ntawm retina thiab dystrophy nyob rau ntawm qhov chaw nyob. Hauv cov menyuam yaus muaj hnub nyoog kawm ntawv, thaum muaj cov kabmob tsom iav, xws li kev hloov, piv txwv li, ntawm cov hlab ntsha ntawm cov hlab ntsha, tej zaum lawv tsis sib haum los ntawm qhov kev ntsuas ntawm lub myopia. Ophthalmometry yuav qhia txog kev txo qis ntawm lub voj voos ntawm lub pob txha thiab qhov nce ntawm nws lub zog kho qhov muag piv rau lub hnub nyoog qis. Ultrasound kev soj ntsuam yuav qhia tau tias qhov loj ntawm lub qhov muag PZO sib raug rau lub hnub nyoog los yog tsawg dua. Nws yog ib qho tseem ceeb heev uas yuav tsum nqa tawm ntawm biometrics ntawm lub qhov muag nyob hauv ob lub dav hlau: kab rov tav thiab sagittal. Nrog lub iav, lub qhov muag khaws ib qho ellipsoidal duab, ntse ntawm ib qho kev noj qab haus huv, txhais tau hais tias nrog ib tus posterior posterior ncej ntawm lub qhov muag. Yog li ntawd, nyob rau hauv kev noj qab nyob zoo, lub kab rov tav yuav loj dua. Tib txoj kev sib raug zoo yog raug rau myopia. Kev kho qhov muag kho kom zoo ntawm lub qhov muag ntawm cov me nyuam yaus txhawb nqa kev ruaj ntseg ntawm txoj kev tsis sib haum xeeb thiab tsis tas yuav muaj kev txhom kho los yog kev phais mob ntxiv.
Ntawm qhov tseem ceeb yog kuaj ultrasound rau lub thib ob variant ntawm myopia, vim qhov loj loj ntawm eyeball. Nws yog raug rau nws raws li qhov nce ntawm qhov ntev ntawm lub anteroposterior thiab kab rov tav ntawm lub qhov muag. Thiab vim hais tias ntawm lub ellipsoidal duab, qhov loj ntawm ob yog tseem me me loj. Hmoov tsis, nrog rau qhov sib txawv ntawm myopia, qhov tsis zoo ntawm qhov muag ntawm tus eyeball tej zaum yuav tsis yog tsuas yog rau heredity, tab sis kuj mus intrauterine yam tseem ceeb uas ua rau kev cuam tshuam nyob rau hauv lub tsim ntawm eyeball. Nyob rau hauv ib tug xov tooj ntawm cov neeg mob, nws muaj peev xwm yog ib tug fetal intrauterine tus kab mob, kev qaug cawv ntawm tus me nyuam hauv plab. Cov tsos mob tshwm sim muaj nyob rau hauv daim ntawv ntawm cov laus pigmented chorioretinal foci los yog pom lub ntsej muag dawb me ntsis ntawm lub periphery ntawm retina. Nws ntseeg tau hais tias nws yog nyob rau hauv cov rooj plaub no uas yuav muaj qhov txo qis tshaj qhov pom tseeb, uas yog hu ua "amblyopia" (feem ntau tsis kho mob). Nyob rau hauv cov neeg mob uas muaj qhov muag tsis pom loj heev, ib qho kev pom zoo ntawm hom mob autosomal kuj yog feem ntau pom, feem ntau ua rau txoj kev loj hlob ntawm cov nyhuv meopia. Nws yog tseeb tias tib txoj kev los tswj cov neeg mob cov tsom iav no yog qhov muaj kuab txhim kho cov tsom iav tsis zoo los yog cov iav ntsiab muag (nrog myopia ntawm qib siab) rau kev tiv thaiv ntawm amblyopia thiab kev mob ntawm myopia. Nws yog ib qho tseem ceeb uas qhia txog tias muaj tus mob myopia ntau tshaj 2 D, ntau tus kws kho mob hais tias yuav tsum tau hnav cov cuab yeej siv kho thaum ua haujlwm zoo. Qhov no yuav pab kom tsis txhob muaj kev sib txuas ntxiv nrog rau kev txhim kho qhov muag ntawm qhov muag, tiv thaiv qhov tsis muaj zog ntawm cov kev pab thiab qhov kev mob ntawm myopia. Ntawm chav kawm, nyob rau hauv lub xeev ruaj ntseg ntawm myopia, cov me nyuam no tsis tas yuav tsum muaj cov sclera-hardening surgeries. Hmoov tsis, kev kho qhov muag tsis pom kev thiab qhov muag khaus qhov muag tau tuaj yeem cuam tshuam txoj kev kawm ntawm myopia. Thiab sai nws tshwm sim, qhov ntau dua malignant nws yog thiab yuav ua rau nyuaj iopia. Hauv cov zauv no nws yog ib qhov tsim nyog yuav tau ua kom muaj kev kho mob uas tswj kev ruaj ntseg ntawm txoj kev tshem tawm cov mob iv.
Tom qab 5 xyoo nrog kev ruaj khov iopia, cov lus nug txog kev kho qhov phais kho qhov muag yuav tau tham txog. Thiab thawj variant ntawm myopia yog yuav luag tsuas yog cov ntaub ntawv ntawm pathogenetic orientation ntawm keratorefrakion ua hauj lwm. Hauv particular, excimer laser correction, thaum ib tug tiag tiag "ntxhab" cornea yog yeej txiav tawm hauv txoj kev loj hlob ntawm myopia. Tam sim no peb paub tias yuav ua li cas kom tsis txhob muaj qhov kev paub ntawm myopia hauv cov me nyuam.
