Txheej txheem cej luam

Metamorphopsia yog qhov pom kev tsis zoo uas ua rau cov khoom sawv, xws li kab ntawm kab sib chaws, txhawm rau saib curvy lossis puag ncig. Nws tshwm sim los ntawm teeb meem nrog lub qhov muag ntawm lub qhov muag retina, thiab, tshwj xeeb, macula.

Retina yog cov roj hlwb txheej nyias nyob tom qab ntawm lub qhov muag uas pom lub teeb thiab xa - ntawm cov duab hluav taws xob zoo-xa mus rau lub hlwb, tso cai rau koj pom. Lub macula zaum nyob hauv plawv ntawm tus retina thiab pab koj kom pom yam hauv kev nthuav dav. Thaum twg ib yam ntawm cov no cuam tshuam los ntawm tus kab mob, raug mob, lossis hnub nyoog, metamorphopsia tuaj yeem tshwm sim.

Cov tsos mob metamorphopsia

Metamorphopsia cuam tshuam txog lub zeem muag hauv nruab nrab (piv rau qhov nruab nrab, lossis ib sab ntawm lub zeem muag) thiab cuam tshuam qhov pom ntawm cov khoom seem. Nws tuaj yeem tshwm sim hauv ib qho muag lossis ob qho tib si. Thaum koj muaj metamorphopsia, koj yuav pom tias:

• Cov khoom ncaj, zoo li qhov chaw cim, tshwm sim laim ntoom.
• Yam khoom tiaj tus, xws li daim paib nws tus kheej, saib puag ncig.
• Cov duab, xws li lub ntsej muag, tuaj yeem tshwm sim distorted. Qhov tseeb, qee qhov tau piv metamorphopsia mus saib Picasso pleev xim, nrog nws txoj kev ua tiav.
• Cov khoom tshwm me dua li lawv (hu ua micropsia) lossis loj dua lawv (macropsia). Raws li kev tshawb fawb luam tawm hauv Kev Tshawb Fawb Ophthalmic, micropsia muaj ntau dua li macropsia.

Metamorphopsia ua rau

Metamorphopsia tuaj yeem yog cov tsos mob ntawm ntau qhov muag pom uas cuam tshuam rau qhov retina thiab macula. Cov no suav nrog:

Hnub nyoog ntsig txog macular degeneration (AMD)

Qhov no yog ib qho kev tsis sib xws, kev cuam tshuam tsis zoo cuam tshuam rau macula, ib feem ntawm lub qhov muag uas cia koj pom cov khoom hauv lub ntsej muag kom pom tseeb thiab zoo nkauj. Lub koom haum qhov muag National tshaj tawm tias muaj feem cuam tshuam txog hnub nyoog macular degeneration (AMD) yog:

• qhov ua rau pom kev ploj ntawm cov 50 thiab laus dua ntawd
• tsis apt tshwm sim kom txog thaum muaj hnub nyoog 60 xyoo
• txuas rau noob caj noob ces
• cuam ​​tshuam txog ib puag ncig cov khoom noj xws li kev noj haus thiab haus luam yeeb

Hauv ib saib ntawm AMD thiab metamorphopsia:

• 45 feem pua ​​ntawm cov kev kawm tshawb pom muaj qhov cuam tshuam txawv ntawm kab (piv txwv li ntawv tshaj tawm xov xwm lossis tshuab computer)
• 22.6 feem pua ​​pom tias tsis txawv txav ntawm lub qhov rai thaib lub thawv ntawv
• 21.6 feem pua ​​muaj kev sib faib ntawm cov kab ntawm cov chav dej chav dej
• 18.6 feem pua ​​ntsib cov ntsej muag txawv txawv

Kev ntub dej AMD yog yuav tsim cov metamorphopsia ntau dua li qhuav AMD. Ntub AMD yog qhov tsis tshua muaj tshwm sim hauv cov hlab ntsha tuaj yeem ua rau cov ntshav thiab kua dej thiab vim li ntawd, ua rau macula ua puas tsuaj. Hauv qhov AMD qhuav, cov macula tau ua kom nyias nyias vim muaj hnub nyoog thiab cov rog ua rog (hu ua drusen) lo hauv qab, ua rau tsis pom kev.

Kev puas tsuaj rau lub qog ua qog (ERMs)

ERMs (epiretinal week) tseem hu ua macular puckers. Lawv tau tshwm sim los ntawm ib qho kev puas tsuaj nyob rau sab hauv qab ntawm cov retina. Qhov kev tsis zoo no tuaj yeem tshwm sim los ntawm lub hnub nyoog, kua muag ntshav, thiab cov kab mob zoo li ntshav qab zib, uas cuam tshuam rau cov hlab ntsha hauv qhov muag.

ERMs pib los ntawm cov noob hlav tuaj rau ntawm cov pob txha mos uas du. Txoj kev loj hlob ntawm tes no tuaj yeem cog lus uas rub tawm ntawm qhov retina thiab ua rau pom kev tsis pom kev.

Kwv yees li 20 feem pua ​​ntawm cov neeg Asmeskas hnub nyoog tshaj 75 xyoos muaj ERMs, txawm hais tias tsis yog txhua kis mob yuav loj txaus uas yuav tsum tau kho.

Macular edema

Nov yog yam xwm txheej uas cov kua dej ntws tawm hauv lub macula. Cov kua dej no tuaj yeem nqus tawm los ntawm cov hlab ntshav ib puag ncig uas tau puas vim yog:

• kab mob zoo li mob ntshav qab zib
• qhov muag phais
• qee qhov mob cuam tshuam (xws li mob uveitis, lossis mob tawm ntawm lub qhov muag uvea lossis txheej nruab nrab ntawm lub qhov muag)

Cov kua dej ntxiv no ua rau cov macula yuav o thiab ua rau tuab, ua rau lub zeem muag tsis pom kev.

Retinal kev ua haujlwm

Thaum tus retina rhuav tshem ntawm cov qauv uas txhawb nws, kev pom kev cuam tshuam. Qhov no tuaj yeem tshwm sim vim kev raug mob, kab mob, lossis kev raug mob.

Lub tsev khaws puav pheej no yog kev kho mob xwm txheej ceev thiab yuav tsum tau kho tam sim kom tiv thaiv qhov tsis pom kev mus tas li. Cov tsos mob muaj xws li "ntab" (cov kab tawm hauv koj lub zeem muag) lossis teeb pom kev hauv koj lub qhov muag.

Macular lub qhov

Raws li lub npe cuam tshuam, qhov macular yog qhov tsim kua muag me me lossis tawg hauv lub macula. Qhov kev tawg no tuaj yeem tshwm sim vim muaj hnub nyoog. Nws tshwm sim thaum lub gel uas muab lub qhov muag nws puag ncig lub cev ntsws thiab sib cog lus, rub tawm ntawm tus pas nrig retina thiab ua kua muag.

Macular qhov feem ntau tshwm sim hauv cov laus tshaj 60. Yog tias ib lub qhov muag cuam tshuam, koj muaj 10 txog 15 feem pua ​​ntawm kev txhim kho nws hauv lwm qhov muag.

Kev kuaj mob Metamorphopsia

Cov kws kho mob siv ntau cov tswv yim - feem ntau muaj cov duab kos lossis cov duab kab nrog cov kab - los pab kuaj mob metamorphopsia. Cov tib neeg uas pom qhov tsis txaus ntseeg nyob rau hauv kab thaum tsis muaj ib qho feem ntau yuav muaj teeb meem retina lossis macular thiab tom qab metamorphopsia.

• Amsler daim phiajCov. Koj tus kws kho mob yuav hais kom koj saib ntawm qee yam hu ua Amsler daim phiaj. Zoo li cov ntawv kab sib chaws siv nyob rau hauv chav kawm geometry, nws tau sib txig sib luag ntawm cov kab rov tav thiab ntsug nrog cov kab nruab nrab.
• Xav pom qhov ncaj ncees hyperacuity puag ncig (PHP). Qhov no yog ib qho kev sim uas pom cov kab uas muaj cov distortions raug nthuav tawm ua ntej koj. Koj yuav raug xaiv los xaiv seb cov kab twg yog misaligned thiab uas tsis yog.
• M-kab kos. Cov no yog cov kab kos nrog ib lossis ob qho ntawm txoj kab ntsug ua los ntawm cov me me me, dua nrog lub hauv paus focal.

Kev kho mob Metamorphopsia

Txij li thaum metamorphopsia yog cov tsos mob ntawm qhov retina lossis teeb meem macular, kho cov mob hauv qab yuav tsum txhim kho lub zeem muag distorted.

Piv txwv li, yog tias koj muaj AMD ntub, koj tus kws kho mob yuav pom zoo kom phais laser kom tsis txhob los ntshav qeeb ntawm cov hlab ntsha hauv koj lub qhov txhab.

Yog tias koj muaj AMD qhuav, tej zaum yuav kom koj noj qee yam tshuaj ntxiv, xws li cov vitamins C thiab E, lutein thiab zeaxanthin uas pom tias ua rau qeeb qeeb.

Yog tias koj muaj lub retina detached, phais kom rov kho nws yuav tsim nyog. Muaj feem xyuam metamorphopsia yuav tsum txhim kho - tab sis nws yuav siv sijhawm. Hauv ib txoj kev tshawb nrhiav, ntau tshaj ib nrab ntawm cov kev kawm tseem muaj qee cov metamorphopsia hauv ib xyoos tom qab kev phais tiav rau cov kab mob retina uas ua tiav.

Txheeb cais metamorphopsia

Lub zeem muag pom kev uas yog qhov pom ntawm metamorphopsia yog cov tsos mob tshwm sim ntawm retina thiab macular qhov muag teeb meem. Nyob ntawm cov mob hauv qab thiab qhov mob hnyav, qhov metamorphopsia yuav yog qhov tseem ceeb lossis tsis. Feem ntau, txawm li cas los xij, ib zaug kev mob qhov muag uas ua rau qhov teeb meem kho tsis pom kev zoo, cov metamorphopsia txhim kho.

Tham nrog kws kho mob yog tias koj pom muaj qhov txawv txav hauv koj lub zeem muag. Ib yam li ntau yam, kev paub ua ntej thiab kev kho mob ua rau muaj txiaj ntsig zoo.
