Tiyeni tiphunzire za mayeso a VEP (Visual Evoked Potential Test), omwe amafufuza kulumikizana pakati pa masomphenya anu ndi ubongo wanu.

Mwina dokotala anakuuza kuti, 'Kodi tichite mayeso a `(VEP)`?' Akanena zimenezo, funso laling'ono limabwera m'maganizo, sichoncho, 'Kodi `(VEP)` iyi ndi chiyani?' Lero tikambirana za mayeso otchedwa visual evoked potential test, kapena monga tonse tikudziwira, mayeso a `(Visual Evoked Potential)` kapena `(VEP)` . Awa ndi mayeso apadera omwe amayang'ana momwe ubongo wanu umagwirira ntchito yokhudzana ndi masomphenya. Musachite mantha, izi si nkhani yayikulu monga momwe mukuganizira.

Kodi mayeso a VEP awa akuyang'ana chiyani kwenikweni?

Chabwino, tsopano tiyeni tiwone chomwe mayeso a `(VEP)` amachita . Mwachidule, mukayang'ana chinthu, chimayesa momwe cortex yowoneka muubongo wanu imayankhira ku chilimbikitso chowona, mwachitsanzo ngati imatulutsa chizindikiro chamagetsi komanso momwe imachitira mwachangu. Izi zimatchedwanso `(Visual Evoked Response)` kapena `(VER)`.

Taganizirani ngati diso lanu ndi kamera. Mukajambula chithunzi ndi kamera imeneyo, muyenera kusamutsa chidziwitsocho kuchokera pachithunzicho kupita ku ubongo wanu, sichoncho? Njira yomwe imanyamula uthengawo imatchedwa `Visual Pathway` . `(VEP)` imayang'ana makamaka ngati njira iyi ikugwira ntchito bwino. Njira yowonera iyi imaphatikizapo:

• Maso Anu ('Maso')
• Mitsempha Yowona - Izi zili ngati zingwe zomwe zimanyamula mauthenga ochokera m'diso kupita ku ubongo. Ndi gawo lofunika kwambiri.
• Optic Chiasm - Apa ndi malo achilendo mkati mwa ubongo wanu. Apa ndi pomwe ulusi wina wa mitsempha ya maso kuchokera ku diso limodzi umadutsana ndi ulusi wa mitsempha wochokera ku diso lina.
• Njira Yowonera - Njira yomwe imanyamula chidziwitso kuchokera ku retina kupita ku ubongo.
• Kuwala kwa Optic - Umu ndi momwe chidziwitso chowoneka kuchokera ku retina yanu, mitsempha ya optic, ndi disc ya optic chimafalikira ku ubongo.
• Cerebral Cortex - Malo ofunikira kwambiri ogwirira ntchito yokonza ndi kumvetsetsa chidziwitso mu ubongo .

Kotero, ngati pali vuto lililonse kapena vuto lililonse panjira yowonera kapena mu cortex yowonera ya ubongo wanu, titha kulizindikira kuchokera ku zotsatira za mayeso a `(VEP)`.

Ndi matenda ati omwe angadziwike ndi mayeso a VEP?

Tsopano mwina mukuganiza kuti, 'Chabwino, izi zikunena za kuyang'ana zinthu zokhudzana ndi masomphenya, ndiye ndi matenda amtundu wanji omwe angazindikire?' Kwenikweni, mayeso a `(VEP)` nthawi zambiri amagwiritsidwa ntchito pothandiza kuzindikira matenda ena.Kapena ngati chizindikiro cholozera mbali imeneyo.

Chifukwa chachikulu chomwe madokotala amalamula mayesowa ndi cha anthu omwe ali ndi matenda otchedwa Multiple Sclerosis (MS) . Anthu ambiri omwe ali ndi MS amatha kukhala ndi matenda otchedwa Optic Neuritis. Apa ndiye kuti mayesowa ndi ofunikira kwambiri.

Si zokhazo, koma izi zimathandiza kuzindikira matenda ena ambiri:

• Chotupa chomwe chimapangika pa mitsempha yanu ya maso, chotchedwa glioma . Izi nthawi zambiri zimagwirizanitsidwa ndi vuto lotchedwa Neurofibromatosis type 1.
• Kutsekeka kwa njira zanu zowonera, mwachitsanzo, chifukwa cha hydrocephalus kapena pituitary adenoma .
• Kuwonongeka kwa njira yowonera chifukwa cha kuvulala mutu kapena ubongo .
• Matenda a Toxic Optic Neuropathy, omwe angayambitsidwe ndi mankhwala enaake kapena zinthu zina zoopsa monga carbon monoxide .
• Mitundu ina ya matenda a optic neuropathy, mwachitsanzo , Anterior Ischemic Optic Neuropathy .
• Mavuto ndi maso omwe amayamba chifukwa cha matenda. Mwachitsanzo, chifuwa chachikulu cha meningeal .

Mayesowa angathandizenso kuwona kuchuluka kwa matenda ena omwe adziwika kale kuti ndi owononga mitsempha . Zitsanzo zina ndi izi:

• Matenda a Multiple Sclerosis ( MS )
• Matenda a Leber Optic Neuropathy (LON)
• Mtundu wa Kjer Dominant Optic Neuritis (DON)
• Friedrich's Ataxia

Kodi mayeso a VEP awa amagwira ntchito bwanji?

Chabwino, tsopano tiyeni tiwone momwe mayeso a `(VEP)` amachitikira, ndi zomwe zimachitika . Izi sizowopsa monga momwe mungaganizire, ndi njira yosavuta kwambiri.

Amalumikiza ma electrode ang'onoang'ono angapo kumadera enaake a mutu wanu, kapena chigaza chanu. Izi zimakhala ngati zomata zazing'ono. Kenako mumawonetsedwa chithunzithunzi chowoneka bwino. Nthawi zambiri iyi ndi njira yowunikira yowonera .

Ma electrode omangiriridwa kumutu wanu amapanga mauthenga amagetsi omwe amayenda pakati pa maselo a ubongo wanu.Kuyeza. Pamene mawonekedwe a chessboard akuwala, cortex yanu yowona imayankha ndipo imayesa kumvetsetsa chidziwitsocho. Panthawiyo, ntchito yamagetsi muubongo wanu imalembedwa ndi ma electrode amenewo. Madokotala amachita mayeso a ``(VEP)`` pamodzi ndi ``Electroencephalogram`` (``EEG```) . Izi zikutanthauza kuti amawonanso ntchito yamagetsi ya ubongo wanu.

Chomwe makina awa a `(VEP)` amachita ndikukuwonetsani zolimbikitsa maso kangapo ndikutenga mtengo wapakati wa zizindikiro zochokera ku `(EEG)` nthawi iliyonse. Pamenepo ndi pomwe mutha kuwunika bwino momwe njira yanu yowonera imagwirira ntchito. Makinawa amalemba mayankho amagetsi ochokera muubongo wanu m'njira zingapo, kapena `zotsatira`. Mukudziwa, pali `ma waveforms` enieni muubongo wanu (visual cortex), omwe amapezeka nthawi zina poyankha zolimbikitsa maso.

Katswiri amafufuza mafunde awa kuti awone ngati pali zochitika zachilendo, zomwe zingamuthandize kumvetsetsa mtundu wa vuto lomwe lingakhalepo m'munda wanu wowonera.

Kodi muyenera kukonzekera bwanji musanayese mayeso?

Palibe chifukwa chochita khama kwambiri pokonzekera mayeso a `(VEP)` awa. Koma pali zinthu zingapo zomwe muyenera kukumbukira.

Dokotala wanu adzakuuzani zonse zomwe muyenera kudziwa zokhudza mayesowa komanso zomwe mungachite musanachite. Ngati muli ndi mafunso kapena nkhawa, onetsetsani kuti mwafunsa . Chofunika kwambiri ndikukonzekera monga momwe akunenera.

Muyenera kusunga tsitsi lanu loyera tsiku lisanafike mayeso, kapena m'mawa wa mayeso. Ndi bwino kusamba ndikutsuka tsitsi lanu. Musamaike mankhwala opopera tsitsi, mafuta, kapena ma gels pa tsitsi lanu. Chifukwa, ngati muli ndi chilichonse mwa zinthu zimenezo, chingasokoneze ma electrode omwe ali pamutu panu kuti asagwire bwino ntchito. Ndicho chokha chomwe muyenera kuchita. N'zosavuta kwambiri, sichoncho?

Kodi chimachitika ndi chiyani panthawi ya mayeso?

Popeza pali mitundu ingapo ya mayeso a `(VEP)`, momwe amachitikira amatha kusiyanasiyana pang'ono. Koma nthawi zambiri zimakhala motere:

• Wogwira ntchito zachipatala adzalumikiza ma electrode angapo, omwe amawoneka ngati mbale zazing'ono zachitsulo, kumadera enaake a chigaza chanu . Izi zimalumikizidwa ndi mtundu wapadera wa guluu womwe ungachotsedwe mosavuta. Ma electrode awa amalumikizidwa ku makina. Makinawo ndi omwe amapatsa dokotala chidziwitso chokhudza momwe ubongo wanu umagwirira ntchito.
• Kenako, mudzafunsidwa kuti muphimbe diso limodzi ndi chigamba ndikuyang'ana chowunikira ndi diso lina. Chowunikiracho chidzawonetsa kuwala kwa maso (nthawi zambiri mawonekedwe a checkerboard). Mukamaliza kuyesa diso limodzi, diso linalo lidzayesedwanso chimodzimodzi.

Simudzamva kupweteka kulikonse mukamachita izi. Mungamve kusasangalala pang'ono chifukwa muyenera kukhala pamalo omwewo kwa kanthawi. Koma palibe chodetsa nkhawa. Mutha kukhala chete.

Kodi mayesowa amatenga nthawi yayitali bwanji?

Mayeso onsewa angatenge mphindi 60, kapena ola limodzi, kuti amalize. Nthawi zina amatha kucheperapo kapena kupitirira apo. Choncho konzekerani zimenezo ndipo patulani nthawi.

Kodi zotsatira za mayeso zikuti chiyani?

Akamaliza mayeso a `(VEP)`, katswiri adzafufuza zotsatira mosamala. Kenako adzakonza `lipoti` ndikulitumiza kwa dokotala wanu. Pokhapokha dokotala wanu adzakufotokozerani zotsatira zake.

Mayeso a `(VEP)` awa amatha kuzindikira mavuto osiyanasiyana m'munda wanu wowonera. Kutengera ndi vutoli, mawonekedwe a mafunde ndi nthawi yomwe ubongo umayankha kuyambira nthawi yomwe chilimbikitsocho chaperekedwa zimasiyana. Mwachitsanzo, mu `demyelinating conditions` zomwe zimawononga myelin sheath ya mitsempha ya optic (monga `(MS)`), mayeso a `(VEP)` adzawonetsa kuti ubongo wanu wachedwa kuyankha. Izi zikutanthauza kuti uthengawo umatenga nthawi yayitali kuti ufike.

Kumbukirani, ngakhale zotsatira za mayesowa zitasonyeza zinazake, dokotala wanu angakufunseni kuti muchite mayeso ena kuti mutsimikizire. Choncho musachite mantha nthawi yomweyo. Lankhulani ndi dokotala wanu ndipo mufotokozereni zonse.

Dokotala wanu adzakufotokozerani mwatsatanetsatane zotsatira zake. Adzakuuzaninso ngati pakufunika mayeso ena. Adzakupatsaninso malangizo a zomwe mungachite kenako.

Pomaliza, ndiyenera kukuuzani izi.

Mayeso a Visual Evoked Potential (VEP) ndi mayeso osavuta, osavulaza omwe angathandize kuzindikira matenda ena omwe amakhudza momwe maso ndi ubongo wanu amagwirira ntchito poyang'anira zinthu zowoneka. Simudzamva kupweteka kulikonse panthawi ya mayeso.

Dokotala wanu adzakufotokozerani zonse musanayesedwe komanso mutatha kuyezetsa. Ngati muli ndi mafunso kapena nkhawa zilizonse, musaope kufunsa . Gulu lanu lachipatala lilipo kuti likuthandizeni. Chifukwa chake, ngati dokotala wanu akukuuzani kuti muchite mayeso ngati awa, musachite mantha mosafunikira, chabwino? Izi zikungokuthandizani kupeza zambiri zofunika zokhudza thanzi lanu.
