Lɛ wi lan bɔt di VEP tɛst (Visual Evoked Potential Test), we de chɛk di kɔnekshɔn bitwin yu vishɔn ɛn yu bren.

Sɔntɛm dɔktɔ tɛl yu se, 'Wi go du `(VEP)` tɛst ?' Wen im tok dat, smol kweshon de kom fo maind, no bi so, 'Wetin bi dis `(VEP)`?' Tide wi go tɔk bɔt di tin we dɛn kɔl visual evoked potential test, ɔ as wi ɔl no am, di `(Visual Evoked Potential)` ɔ `(VEP)` tɛst. Dis na rili spɛshal tɛst we de luk aw yu bren de wok we gɛt fɔ du wit di we aw yu de si tin. Nɔ fred, dis nɔto big tin lɛk aw yu tink.

Wetin ɛksaktɔli dis VEP tɛst de luk fɔ?

Okay, naw lɛ wi si wetin ɛksaktɔli dis `(VEP)` tɛst de du . fכ simpul wan, we yu luk sכmtin, i de mכsu aw di vishכnal kכtεks na yu bren de rεspכnd to da vishכnal stimulus de, i.e. if i de gi ilektrikal signal εn aw i de du am kwik. Dɛn kin kɔl dis bak `(Visual Evoked Response)` ɔ `(VER)`.

Tink bɔt am lɛk se yu yay na kamɛra. We yu tek pikchɔ wit da kamɛra de, yu nid fɔ transfa di infɔmeshɔn frɔm da pikchɔ de to yu bren, nɔto so? Di rod we de kɛr da mɛsej de na in dɛn kɔl di `Visual Pathway` . Di `(VEP)` men wan de chɛk if dis pat de wok fayn. Dis we aw pɔsin kin si tin inklud:

• Yu yay (`Ay`) .
• Optik Nεv dεm - dεn ya lεk kεbul dεm we de kכri mεsej frכm di yay to di bren. Dɛn na pat we rili impɔtant.
• Optic Chiasm - Dis na wan strenj ples insay yu bren. dis na di say we sכm pan di optik nεv fayb dεm frכm wan yay kכros wit di nεv fayb dεm frכm di כda yay.
• Optik Trakt - na di rod we de kכri infכmeshכn frכm di rεtina to di bren.
• Optik Rεdyushכn - Dis na aw di infכmeshכn we yu de si frכm yu rεtina, optik nεv, εn optik disk de transmit to di bren.
• Sεribral Kכtεks - di men infכmeshכn prכsεsin εn כndastandin sεntr כm na di bren .

So, if eni abn כmaliti כ prכblεm de na di vishכnal path כ di vishכnal kכtεks na yu bren, wi kin no am frכm di risכlt fכ di `(VEP)` tεst.

Us sik dɛn kin no bay di VEP tɛst?

Naw yu go de tink se, ‘Okay, dis na fɔ luk tin dɛn we gɛt fɔ du wit vishɔn, so us kayn sik i go ebul fɔ no?’ fכ tru, dεn kin yus di `(VEP)` tεst fכ εp fכ no sכm mεdikal k כndyushכn dεm.Ɔ as hint fɔ pɔynt to da dairekshɔn de.

Di men rizin we mek dɔktɔ dɛn kin ɔda dis tɛst na fɔ pipul dɛn we gɛt wan sik we dɛn kɔl Multiple Sclerosis (MS) . Bɔrku pipul dɛm wae gɛt MS kin gɛt wan sik wae dɛn kɔl Optic Neuritis. Dis na di tɛm we dis tɛst rili impɔtant.

Nɔto dat nɔmɔ, bɔt dis kin ɛp fɔ no bɔku ɔda tin dɛn we kin apin:

• Wan tumbu we kin mek na yu optik nɛv, we dɛn kɔl glioma . dis kin kכmכt wit wan kכndyushכn we dεn kכl Nyurofibromatosis tayp 1.
• Fɔ ɛgzampul, we yu nɔ ebul fɔ si di wata we yu de si bikɔs ɔf haydrosɛfalɔs ɔ wan pituitary adenoma .

Aw dis VEP tɛst de wok?

Okay, naw lɛ wi si aw ɛksaktɔli dɛn de du dis `(VEP)` tɛst, ɛn wetin de apin . Dis nɔr big ɔr frayd lɛk aw yu kin tink, na rili simpul prɔses.

Dɛn kin tay sɔm smɔl smɔl ilɛktrɔd dɛn na sɔm patikyula say dɛn na yu ed, ɔ yu skel. Dɛn tin ya tan lɛk smɔl smɔl stika dɛn. Dɔn dɛn sho yu wan tin we yu kin si. Bɔku tɛm dis na wan pɔtn we de flash .

di ilektroyd dεm we de atak yu skel de mek ilektrikal signal dεm (mεsej dεm) we de travul bitwin yu bren sεl dεm.Fɔ mɛzhɔ. We da chɛsbɔd patɛn de flash, yu visual kɔtɛks de ansa am ɛn tray fɔ mek sɛns to da infɔmeshɔn de. Na da tɛm de, dɛn ilɛktrɔd dɛn de kin rayt di ilɛktrik wok we de na yu bren. Dכkta dεm de du dis ``(VEP)`` tεst in kכnjכkshכn wit wan ``Ilektroεnεsεfalogram`` (``EEG``) . Dat min se dɛn kin luk bak pan di nɔmal ilɛktrik aktiviti na yu bren.

wetin dis `(VEP)` mashin de du na fכ sho yu dat vishכnal stimulus sεvεra tεm εn tek wan avrej valyu fכ di signal dεm we de kכmכt frכm di `(EEG)` εvri tεm. Na da tɛm de yu kin ebul fɔ asɛs di wok we yu de du we yu de si fayn fayn wan. dis mashin de rεkכd di ilektrikal rispכns dεm we de kכmכt frכm yu bren insay sεvεra chanεl dεm, כ `trays`. yu no, spεsifi k `wevfכm` dεm de na yu bren (visual kכtεks), we de apin na rili spεsifi k tεm dεm we de ansa to wan vishכnal stimulus.

Dɔn wan spɛshal pɔsin kin analayz dɛn wef patɛn ya fɔ si if ɛnitin de we nɔ kɔmɔn, we kin ɛp am fɔ ɔndastand us kayn prɔblɛm kin de na di say we yu de si.

Aw yu fɔ pripia bifo di tɛst?

Natin nɔ de we yu rili nid fɔ du fɔ pripia tumɔs fɔ dis `(VEP)` tɛst. Bɔt sɔm tin dɛn de we wi fɔ mɛmba.

Yu dɔktɔ go tɛl yu ɔl wetin yu nid fɔ no bɔt di tɛst ɛn wetin fɔ du bifo dɛn du am. If yu gɛt ɛni kwɛstyɔn ɔ sɔntin we de mɔna yu, mek shɔ se yu aks . Di tin we impɔtant pas ɔl na fɔ rɛdi lɛk aw dɛn se.

Yu nid fɔ kip yu ia klin di de bifo di tɛst, ɔ di mɔnin fɔ di tɛst. I bɛtɛ if yu ebul fɔ shaw ɛn was yu ia. Nɔ put ɛni sprɛy fɔ yu ia, ɔyl, ɔ jel pan yu ia. Bikɔs, if yu gɛt ɛni wan pan dɛn tin dɛn de, i kin ambɔg di ilɛktrɔd dɛn we de na yu ed fɔ wok fayn fayn wan. Na dat nɔmɔ yu rili gɛt fɔ du. I rili izi, nɔto so?

Wetin kin apin we dɛn de du di tɛst?

Bikɔs sɔm kayn `(VEP)` tɛst dɛn de, di we aw dɛn kin du am kin difrɛn smɔl. Bɔt i kin go sɔntin lɛk dis:

• Wan pɔsin we de wok na di dɔktɔ go tay bɔku ilɛktrɔd dɛn, we tan lɛk smɔl smɔl mɛtal plet dɛn, na sɔm patikyula say dɛn na yu skel . Dɛn kin tay dɛn tin ya wit wan spɛshal kayn adeziv we pɔsin kin pul izi wan. Dɛn kin kɔnɛkt dɛn ilɛktrɔd dɛn ya to wan mashin. Di mashin na di wan we de gi di dɔktɔ infɔmeshɔn bɔt aw yu bren de wok.
• Dɔn, dɛn go aks yu fɔ kɔba wan yay wit pat ɛn luk monita wit di ɔda yay. Di monita go sho di flashin vijual stimulus (bɔku tɛm na chɛkbɔd patɛn). We yu dɔn fɔ tɛst wan yay, dɛn go tɛst di ɔda yay di sem we.

Yu nɔ go fil ɛni pen we yu de du dis. Yu kin fil bad smɔl bikɔs yu fɔ de na di sem pozishɔn fɔ sɔm tɛm. Bɔt natin nɔ de fɔ wɔri bɔt. Yu kin kɔntinyu fɔ de kwayɛt.

Aw lɔng di tɛst kin tek?

Dis ɔl tɛst kin tek lɛk 60 minit, ɔ lɛk wan awa fɔ dɔn. Sɔntɛnde, i kin smɔl smɔl ɔ i kin pas dat. So rɛdi fɔ dat ɛn sɛt sɔm tɛm.

Wetin di tɛst rizɔlt dɛn se?

We dɛn dɔn du di `(VEP)` tɛst, spɛshal pɔsin go stɔdi di rizɔlt fayn fayn wan. Dɔn i go pripia wan `ripɔt` ɛn sɛn am to yu dɔktɔ. Na da tɛm de nɔmɔ yu dɔktɔ go ɛksplen to yu di tin dɛn we dɔn apin.

Dis `(VEP)` test kin no difrεn prכblεm dεm na yu vishכnal fil. dipכnt pan di prכblεm, di shep fכ di wev fכm dεm εn di tεm we i tek fכ di bren fכ ansa frכm di tεm we dεn gi di stimulus go difrεn. fכ egzampl, insay `demyelinating conditions` we de damej di myelin sheath fכ di optik nεv (lεk `(MS)`), di `(VEP)` tεst go sho se yu bren de dilay fכ rεspכnd. Dis min se di mɛsej kin tek lɔng tɛm fɔ pas.

Mɛmba se ilɛksɛf di rizɔlt fɔ dis tɛst sho sɔntin, yu dɔktɔ kin aks yu fɔ du mɔ tɛst fɔ no if yu gɛt am. So nɔ panik wantɛm wantɛm. Tɔk to yu dɔktɔ ɛn ɛksplen ɔltin.

Yu dɔktɔ go ɛksplen to yu di tin dɛn we go apin to yu. Dɛn go tɛl yu bak if dɛn nid fɔ du ɛni ɔda tɛst. Dɛn go gayd yu bak bɔt wetin fɔ du nɛks.

Fɔ dɔn, a fɔ tɛl una dis.

Di Visual Evoked Potential (VEP) test na simpul, non-invasive test we kin ɛp fɔ no sɔm kɔndishɔn dɛn we de afɛkt di we aw yu yay ɛn yu bren de prosɛs di tin dɛn we yu de si. Yu nɔ go fil ɛni pen we yu de du di tɛst.

Yu dɔktɔ go ɛksplen ɔltin to yu bifo ɛn afta di tɛst. If yu gɛt ɛni kwɛstyɔn ɔ sɔntin we de mɔna yu, nɔ fred fɔ aks . Yu mɛdikal tim de fɔ ɛp yu. So, if yu dɔktɔ tɛl yu fɔ du tɛst lɛk dis, nɔ fred am we yu nɔ nid, okay? Dis na jɔs fɔ ɛp yu fɔ no impɔtant tin dɛn bɔt yu wɛlbɔdi biznɛs.
