Lɛ wi lan bɔt wan tɛst we de chɛk yu vishɔn? (Visual Fild Tɛst) .

Yu dɔn ɛva go to ay dɔktɔ ɛn mek dɛn du spɛshal tɛst fɔ si aw fa yu de si? Na dat wi kin kɔl ``Visual Field Test.'' Na tru tru wan rili simpul, we nɔ gɛt pen. So lɛ wi tɔk mɔ bɔt am.

Wetin dis `(Visual Field Test)` de luk pan?

Fɔ tɔk am simpul wan, dis tɛst de mɛzhɔ tu men tin dɛn.

• Na aw fa yu yay kin si ɔp, dɔŋ, lɛft, ɛn rayt we yu luk stret bifo yu nɔ muv yu ed.
• di כda tin na, yu gεt di כl εria we yu kin si (wi kכl dis di `visual field`), εn aw yu vishכn sεnsitiv na εvri pat pan am.

Yu no, wi yay kin si big eria bifo wi wan tɛm. Ivin if yu nɔ muv yu yay, yu nɔ go jɔs si wetin de stret bifo, bɔt yu kin si bak wetin de ɔp, dɔŋ, ɛn na di sayd dɛn. dכkta dεn kכl wetin yu si ausayd dis strεt εria ``pεrifεral vishכn.' ' Wetin yu si stret bifo na ``sɛntral vishɔn.''

nכmal wan, wi kin si mכst klia wan na di midul pan dis `visual fil`. Na dat mek yu de tɔn yu yay fɔ luk sɔntin we yu want fɔ si klia wan. As yu de go fa frɔm di say we yu de si, tin nɔ kin klia. We sɔntin muf tumɔs na di sayd, i kin lɔs na yu yay kpatakpata.

Ustɛm dɛn kin du ``Visual Field Test''?

We yu go to ay dɔktɔ (optometrist ɔ ɔftalmɔlɔjis), dɛn go du visual fild tɛst as pat pan wan rutin ay ɛgzam. Dis kin ɛp yu dɔktɔ fɔ no di fɔs sayn dɛm fɔ sik lɛk glaukoma , we kin pwɛl yu yay smɔl smɔl. Sɔm pipul dɛm wae gɛt glaukoma nɔr kin notis ɛni chenj na dɛn yay fɔs. כltu, wan vishכnal fil tεst kin detekt lכs di pεrifεral vishכn.

Dis tɛst kin tɛl yu ɔda tin bak. I de tɛl yu aw di pat dɛn na di nervɔs sistɛm we de ɛp yu fɔ si de wok. Di pat dɛm na di nervɔs sistɛm we de ɛp yu fɔ si na:

• Yu retina : Dis tan lɛk transdyusɔ insay yu yay. I de tek layt ɛnaji ɛn chenj am to ilɛktrik signal.
• Yu optik nεv : Dis nεv de kכri dεn ilektrikal signal dεm to di bren, usay dεn de kכnvכlt to imej.
• Yu Bren : Dɔn, dɛn sayn dɛn de kin bi di pikchɔ dɛn we yu de si insay yu bren.

Imajin, if prɔblɛm de ɛnisay na dis sistɛm, i kin afɛkt di say we yu de si. Sɔm patɛns dɛn de na di rizɔlt fɔ dis tɛst. If dɔktɔ dɛn luk dɛn patɛns dɛn de, i kin izi fɔ ɔndastand us kayn damej ɔ sik de.

Dɔn bak, bay we yu ripit dis ``Visual Field Test'' na sɔm patikyula tɛm, dɔktɔ dɛn kin si if yu kɔndishɔn de bɛtɛ ɔr de wɔs.

Fɔ us kayn sik dɔktɔ go tɛl yu fɔ du dis tɛst?

If yu gɛt sɔm kayn mɛrɛsin, ɔ if yu dɔktɔ sɔspɛkt se yu gɛt wan, i kin se yu fɔ du ``Visual Field Test''. Dɔktɔ dɛn kin yuz di rizɔlt fɔ dis tɛst fɔ ``diagnose'' ɛn ``monitor'' di kɔndishɔn. Fɔ ɛgzampul:

• `(Glɔkoma)`
• Strok
• Makula dijɛnɛreshɔn
• `(Multiple sclerosis (MS))` (Dis na sik wae de afekt di nervous system)
• `(Graves' disease)` (Dis na sik we gɛt fɔ du wit di tayroyd gland)
• Di sik we de na di pituitary gland
• Blaynd ples (skɔtoma) .

Wetin mek sɔm pipul dɛn fɔ du dis ``Visual Field Test'' bɔku tɛm?

Sɔntɛnde, yu yay dɔktɔ kin aks yu fɔ du dis ``Visual Field Test'' bak kwik fɔ mek shɔ se di rizɔlt kɔrɛkt. Mɛmba se if yu de fil taya, di tɛst rizɔlt nɔ go rili fayn.

Ɔ, yu dɔktɔ kin aks yu fɔ du dis tɛst bak insay sɔm wik, mɔnt, ɔ ivin wan ia. Dis kin ɛp fɔ no ɛni nyu prɔblɛm kwik kwik wan. If yu gɛt sɔm kayn yay kɔndishɔn, yu dɔktɔ go du dis ``Visual Field Test'' ɔltɛm fɔ si aw yu tritmɛnt de wok fayn.

Dis tɛst impɔtant mɔ we yu de trit pipul dɛn we gɛt glaukoma. Ivin if yu nɔr no, if yu de si de go dɔŋ, di dɔktɔ kin no frɔm dis tɛst. Dat na wan rizin we mek pipul dɛn we gɛt glaukoma fɔ go ɛvri apɔntinmɛnt we dɛn dɔktɔ dɔn tɛl dɛn .

Wetin kin apin we yu du `(Visual Field Test)`?

No spɛshal pripia nɔ de we yu nid fɔ dis `(Visual Field Test). I nɔ de invasive, so di chans fɔ mek yu gɛt ɛni sayd ɛfɛkt rili smɔl.

Bɔku kayn ``Visual Field Test'' de. Bɔt dɛn ɔl gɛt wan tin we kɔmɔn: yu fɔ luk stret bifo yu na wan say, dɔn yu fɔ siŋ say we yu si sɔntin ɔ layt na di sayd.

Yu dɔktɔ go ɛksplen to yu ustɛm fɔ luk fɔ du di tɛst kɔrɛkt wan.

Tu besik kayn ``Visual Field Tests`` de, ɛn dɛn rili simpul:

• Amsler grid: Dis tan lɛk skwea grid. Na wan patɛn we gɛt stret layn dɛn we dɛn drɔ insay wan skwea patɛn. Yu luk di big dot we de na di midul. Dɔn, yu tɛl mi if di layn dɛn luk blɔk, rɔtin, ɔ brok na ɛni pat. Di Amsler grid na wan kwik tɛst. Bɔt i jɔs de mɛzhɔ di sɛntrɔm pan yu vishɔnal fil (dɛn kɔl am sɛntral vishɔn). I jɔs de gi di dɔktɔ smɔl infɔmeshɔn.
• `(Confrontation visual field)` test: Insay dis, di wɔd 'confrontation' min se di pɔsin we de du di tɛst de sidɔm bifo di pɔsin we de fes di tɛst, lɛk 3 to 4 fit (lɛk wan mita) away. Di pɔsin we de du di tɛst de ol in an dɛn te i go na di sayd dɛn. Yu fɔ luk stret bifo yu. Dɔn i de briŋ wan an, dɔn di ɔda wan, to yu. Yu fɔ mek sayn jɔs lɛk aw yu si in an.

Ɔda kayn `(Visual Field Test)` de?

Yes, yu kin yɛri bɔt ɔda kayn `(Visual Field Test)` ɛn ɔda nem fɔ dɛn. fכ egzampl, `statik pεrimεtri` εn `kinetik pεrimεtri` tεst dεm. (`Perimetry test` na כda nem bak fכ `pεriferal vishכn tεst`, we min tεst we de chεk pεrifεral vishכn.)

• `(Kinetic perimetry)` test: Insay dis, di pɔsin we de du di tɛst de muv wan tin rawnd, ɛn yu fɔ tɛl dɛn we yu si am. Bɔku tɛm, dɔktɔ dɛn kin yuz di `(Goldmann perimetry test).`
• Statik pεrimεtri tεst: כtomatכt pεrifεral vishכn tεst na wan kayn statik pεrimεtri tεst. Insay dis tɛst, yu de luk insay wan mashin we tan lɛk bɔl. We yu si sɔntin, yu kin prɛs wan bɔtin fɔ sho am. Ɛgzampul dɛn fɔ statik tɛst na di Humphrey ɛn Octopus mashin dɛn.

Aw lɔng wan `(Visual Field Test)` kin tek?

Bɔku tɛm, i nɔ kin tek pas fayv to tɛn minit fɔ wan yay.

Us kayn `(Visual Field Test)` de gi di mɔs ditayla infɔmeshɔn?

Naw, kɔmpyuta inschrumɛnt dɛn de fɔ du di Visual Field Test ɛn kɔl di rizɔlt. Di rizulyt we dɛn kin gɛt frɔm dɛn inschrumɛnt ya kin kɔrɛkt mɔ ɛn dɛn kin riprodyuz. Bɔku rizin dɛn de fɔ dis:

• Yu ed de na wan ples di wan ol tɛm we yu de tek di tɛst.
• Yu kin si se dis divays gɛt big sɛntral ‘target’. So yu kin kip di sɛntrɔm pan di say we yu de si tinap na wan ples.
• Dɛn tin ya kin yuz smɔl smɔl layt dɛn fɔ tɛst di we aw pɔsin de si. Di dɔktɔYu kin mɛzhɔ di sɛnsitiviti fɔ si na ɛni say, ɛn chenj di brayt ɛn kɔlɔ fɔ dis layt.
• Klin standad de fɔ wetin na ‘nɔmal’ rizɔlt. Dis divays kin kɔmpia ɛni nyu tɛst we i de du to dɛn standad ya.

Wetin di rizulyt fɔ di `(Visual Field Test)` se?

Wan 'nɔmal' rizɔlt pan ``Visual Field Test'' min se yu kin si fayn fayn wan lɛk pɔsin we nɔ gɛt ɛni prɔblɛm wit yu si.

Dis tεst de sho aw di vishכn de rεdכks εn us εria dεm de afekt. Di divays de print di rizulyt dɛn as ɔl tu `patterns of dots` ɔ `numbers`. Dɛn patɛns ya kin tɛl yu dɔktɔ aw yu yay ɛn yu vishɔnal fil sistɛm de wok fayn fayn wan. Dis kin ɛp yu dɔktɔ fɔ no wetin na di ɔndalayn wɛlbɔdi prɔblɛm ɛn us tritmɛnt yu nid.

Test we sho se yu nɔ de si fayn, dat min se yu vishɔn nɔ shap lɛk aw i fɔ shap na sɔm say dɛn. De test kin sho se yu nɔr de si fayn fayn wan na smɔl say, ɔr yu nɔr de si fayn fayn wan na big say.

Ustɛm a go no di rizɔlt fɔ di tɛst?

Bɔku tɛm, yu dɔktɔ fɔ ebul fɔ gi yu di rizɔlt wantɛm wantɛm.

If di tin dɛn we kin apin nɔ kin fayn, wetin kin apin afta dat?

Di tin dɛn we nɔ kin apin kin min bɔku difrɛn tin dɛn. dis rizulεt dεm kin sho difrεn kayn prכblεm dεm, lεk `(Glaucoma)`, `(Macular degeneration)` כ `(Stroke`). So, di nεks step dεm (`fכlכ-ap`) kin difrεnt.

Yu yay dɔktɔ go tɔk to yu bɔt di tritmɛnt dɛn we yu go gɛt.

Ustɛm a fɔ kɔl mi dɔktɔ ?

If yu gɛt nyu we aw yu nɔ de si ɔ yu yay nɔ de fil fayn, yu fɔ go to yu yay dɔktɔ ɔltɛm. If yu nɔ ebul fɔ si wantɛm wantɛm ɔ yu yay de fil bad bad wan, yu fɔ go na imejensi rum wantɛm wantɛm.

I fayn fɔ mek yu de chɛk yu yay ɔltɛm. As pat pan yu ɛgzam, i go mɔs bi se yu go gɛt tɛst fɔ si aw yu kin si ɔp, dɔŋ, ɛn na di sayd dɛn na yu yay. If ɛni prɔblɛm de wit yu yay fil, di rizɔlt kin ɛp yu dɔktɔ fɔ no bɔt wan mɛrɛsin we yu go gɛt ɔ si aw di tritmɛnt dɛn we yu de gi yu naw de wok fayn.

So, wetin wi nid fɔ mɛmba frɔm ɔl dɛn tin ya?
