Yu dɔn ɛva du ɛgzam fɔ yu yay? We wi de go, wi kin tink bɔt if wi yay de wɔs ɛn if wi nid glas. Bɔt yu no se dɔktɔ we de mɛn yu yay kin chɛk bɔku mɔ bɔt yu yay? Wan pan dɛn impɔtant tɛst dɛn de na di Visual Field Test. Dis kin tan lɛk se i nɔ izi fɔ du, bɔt na tɛst we rili simpul ɛn we nɔ de mek pɔsin fil pen. Tide, wi go tɔk bɔt ɔltin insay wan rili simpul we.
Fɔ tɔk am simpul wan, wetin na dis Visual Field Test?
Imajin se yu de luk stret bifo yu. di wan ol rεnj we yu kin si we yu luk stret bifo, we yu nכ muv yu ed כ yu yay, dat na, di כl rεnj we yu kin si na כl di dairekshכn, כp, dכn, rayt, εn lεft, na in wi kכl di vishכnal fil.
Fɔ tɔk am simpul wan, ivin we yu de luk stret bifo, yu nɔ go ebul fɔ si ɛnibɔdi we de kɔmɔt na ɛni say, nɔto so? Na dat wi kin kɔl peripheral vision . Wetin yu de luk dairekt na in dɛn kɔl sɛntral vishɔn .
So, wetin dis Visual Field Test de du na fɔ "map" yu ɔl fil fɔ si, dat na, di ɔl rɛnj fɔ wetin yu kin si. I tan lɛk map fɔ Sri Lanka, ɛn i de luk aw yu map we yu de si tan.
Dis tɛst de mɛzhɔ tu men tin dɛn:
1. Aw di say we yu de si tin big? - Dis min aw fa yu kin si ɔp, dɔŋ, lɛft, ɛn rayt we yu luk stret bifo yu nɔ muv yu ed.
2. Aw yu de si fayn? - Insay di ɔl di say we yu de si, sɔm say dɛn kin klia, sɔm say dɛn kin blɔk, ɛn sɔm say dɛn nɔ kin si atɔl. So dis de sho yu bak aw yu vishɔn de sɛnsitiv pan ɛni wan pan dɛn eria ya.
Nɔmal wan, wi yay kin si fayn fayn wan stret bifo. Na dat mek we wi want fɔ si sɔntin klia wan, wi kin tɔn wi ed na da say de ɛn luk stret bifo. As wi de muf go fa frɔm di sɛnt, wi de si smɔl smɔl. We wi muf tu fa, di tin nɔ de igen na wi yay.
Wetin mek dis tɛst rili impɔtant?
We yu go to ay dɔktɔ, yu kin du dis as pat pan di chɛk-ap we yu kin du ɔltɛm. Dis tɛst rili impɔtant bikɔs i kin no sɔm tin dɛn we kin sikrit wan fɔ pwɛl di yay kwik kwik wan, bifo ɛni sayn fɔ sho.
Di bɛst ɛgzampul na wan sik we dɛn kɔl glaukoma . We glaukoma bigin, di prɛshɔn na di yay kin go ɔp, ɛn smɔl smɔl i kin pwɛl di optik nɛv we de kɔnɛkt di yay to di bren. di fכs tin we de lכs na di pεrifεral vishכn. Bɔt bikɔs dis kin apin sloslo, bɔku pipul dɛn nɔ kin notis di difrɛns. כltu, we dεn du vishכnal fil tεst, dεn kin no dis lכs fכ si, dεn "blaynd spat dεm", klia wan.
Dis tɛst de gi di dɔktɔ bɔku tin dɛn bak bɔt aw wi yay sistɛm de wok. Di we aw wi de si tin gɛt tri men pat dɛn:
- Retina: Dis de insay di yay. I tan lɛk di fim we de insay kamɛra. I kin chenj di layt we de go insay di yay to ilɛktrik signal.
- di optik nεv: dis na di "kεbul" we de kכri signal dεm we dεn jεnarεt na di rεtina to di bren.
- Bren: Di bren de tek dɛn signal ya, analayz dɛn, ɛn chenj dɛn to di pikchɔ we wi de si.
If prɔblɛm de na ɛni wan pan dɛn tri eria ya, yu go si am na di rizɔlt fɔ yu Visual Field Test. Spɛshal patɛns de fɔ chenj na dis vishɔnal map we gɛt fɔ du wit difrɛn sik dɛn. We yu dɔktɔ stɔdi dɛn kayn tin ya, i go ebul fɔ gɛs us kayn sik yu gɛt.
Wetin na di men mɛrɛsin wae dɛn kin du dis tɛst fɔ?
If yu gɛt ɛni sayn ɔ yu tink se yu gɛt sik, yu dɔktɔ kin tɛl yu fɔ du dis tɛst. Dɛn kin yuz di rizɔlt fɔ dis tɛst fɔ no di sik ɛn fɔ wach if di sik de ɔnda kɔntrol ɔ i de wɔs.

Wetin mek sɔm pipul dɛn fɔ kɔntinyu fɔ tek dis tɛst?
Dis na kwɛstyɔn bak we bɔku pipul dɛn kin aks. Sɔntɛnde, di dɔktɔ kin du dis tɛst ɛn aks yu fɔ du am bak insay sɔm dez. Ɔ i kin aks yu fɔ du am bak afta sɔm mɔnt, we na wan ia. Bɔku rizin dɛn de fɔ dat.
1. Verifay di rizulyt: Lɛ wi se yu taya di de we dɛn du di tɛst, ɔ yu kɔnsɛntreshɔn nɔ bin fayn. Dɔn, smɔl mistek dɛn kin de na di rizɔlt dɛn. So, yu kin aks fɔ tek di tɛst bak fɔ mek shɔ se di rizɔlt na 100% kɔrɛkt.
2. Monitor yu kondishon: Dis na di men rizin. Ɛspɛshali fɔ pipul dɛm wae gɛt lɔng tɛm sik lɛk glaukoma, yu dɔktɔ go du dis tɛst ɔltɛm.

Wetin kin apin we dɛn de du di tɛst?
Nɔ nid fɔ pripia bɔku di de bifo dis tɛst. Dis nɔto tɛst we de mek di bɔdi gɛt ɛni bad tin ɔ pen.
Bɔku we dɛn de fɔ du Visual Field Test. Bɔt di tin we kɔmɔn pan ɔl dɛn we ya na dat yu fɔ luk stret na wan ples. We yu de du dat, yu fɔ gi signal jɔs afta yu si layt ɔ sɔntin we de kɔmɔt na di tu say dɛn. Yu fɔ gi da signal de bay we yu prɛs wan smɔl bɔtin na yu an.
Fɔ mek yu du di tɛst kɔrɛkt wan, i rili impɔtant fɔ luk bifo yu stret lɛk aw di dɔktɔ ɔ di tɛknishian tɛl yu fɔ du am.
Di simpul we dɛn fɔ tɛst
Dis nɔto rili kɔmplikɛt we dɛn kin du as bɛsik chɛk.
- Amsler Grid: Dis na lɛk skwea rula. I gɛt wan big dɔt na di midul. Na wetin yu fɔ du na fɔ lɔk wan yay ɛn luk di dɔt we de na di midul wit di ɔda yay. As yu de luk, yu fɔ tɛl di dɔktɔ if di layn dɛn na di skwea dɛn strɛch, brok, rɔtin, ɔ blɔk na sɔm say dɛn. Dis kin mɔs tɛst yu sɛntral vishɔn.
- Kɔnfrɛns Visual Fild Tɛst: Insay dis tɛst, di dɔktɔ kin sidɔm bifo yu, lɛk 3 to 4 fit so. Yu lɔk wan yay ɛn luk di dɔktɔ in nos stret. Di dɔktɔ es in an dɛn na di sayd dɛn ɛn briŋ dɛn kam insay Yu fɔ tɛl am we yu si in an. Dis de gi yu wan rough idea of di extent of yu peripheral vision.
