Sikrit dɛn we de insay di yay! Wetin yu rili si wit (Retinal Imaging)?

Yu dɔn ɛva wɔnda wetin de apin insay yu yay? Sɔntɛnde we yu go fɔ chɛk yu yay, di dɔktɔ go se, "Wi nid fɔ tek pikchɔ fɔ di insay pat pan yu yay." na dat dεn kכl am ``Retinal Imaging.'' fכ simpul wan, i de tek dijital pikchכ dεm fכ di insay pat pan yu yay, spεshal wan di rεtina we de na di bak pat pan yu yay. Dis na rili impɔtant tɛst.

So wetin na dis `(Retinal Imaging)`?

Okay, mek wi tok likl mo ditel. yu yay dכkta kin yuz dis tεknכlכji we dεn kכl ` `Retinal Imaging`` fכ tek dijital pikchכ, כ fכto, fכ di dilik pat dεm insay yu yay, di bak pat na yu yay. dis pat na di say we di retina (we dεn kכl bak di makula) εn yu optik nεv de, we rili imכtant.

Bɔku tɛm, wi kin du dis tɛst we wi de du kɔmprɛhnsiv ay ɛgzam, ɔ fɔ si if yu gɛt sɔm ay kɔndishɔn ɛn aw dɛn de kɔntrol dɛn. Imajin, frɔm dɛn pikchɔ ya, wi kin si if yu gɛt sɔm kayn yay sik, ɛn if dɛn nɔ trit dɛn, yu kin lɔs yu yay . Dɔn bak, if yu de tek ɛni tritmɛnt, i kin si aw i kin wok fayn. We di dɔktɔ de tek dɛn pikchɔ ya ɔltɛm fɔ lɔng lɔng tɛm, i kin no kwik kwik wan ivin smɔl chenj dɛn we de insay di yay. Di dɔktɔ go tɛl yu us kayn ``Retinal Imaging'' tɛst yu nid ɛn aw ɔltɛm dɛn fɔ du am.

Wetin wi kin fɛn pan dis tɛst?

Dis na diagnostik test wae kin rili no bɔrku tin. Luk dis list:

• Makula ɛdima we gɛt fɔ du wit dayabitis .
• Di damej pan di retina we dayabitis kin mek dɛn kɔl am dayabitik retinopathy .
• Ay kansa .
• Glaukoma kɔndishɔn .
• Makula dijεnεreshכn (dεm we de apin we di makula de pwεl we i gεt).
• Wan ol na di makula `(Makula ol)` .
• Wan pul ɔ wrinkling pan di makula `(Macular pucker)` .
• inflameshn fכ di `posterior uvea`, we na wan tisu insay di yay, dεn kכl am `posterior uveitis` .
• Di retina we de kɔmɔt na di bɔdi .
• di rεtina vein oklushכn .

Imajin, if dɛn pikchɔ ya sho sɔntin lɛk dis, yu dɔktɔ go tɛl yu di rayt tritmɛnt fɔ yu. Sɔntɛnde yu go gɛt fɔ tek pikchɔ dɛn ɔltɛm na sɔm tɛm dɛn (serial imaging) . Dis na fɔ si aw yu de du ɛn aw di tritmɛnt de wok fayn.

Aw dɛn kin du dis retina imej tɛst?

tri men we dεn de fכ tek dijital imej dεm fכ di bak pat na di yay, di `fundus` (as wi bin se, di `fundus` na di bak pat pan di yay). Di dɔktɔ dɛn we de mɛn di yay kin yuz dɛn we ya.

1. Aw yu de si wit kala fundus foto?

Dis min se yu fɔ tek pikchɔ dɛn insay yu yay bay we yu de yuz tin dɛn we dɛn kɔl fundus kamera. Dɔktɔ dɛn dɔn de yuz dis we fɔ lɔng lɔng tɛm. We di kamɛra tek di pikchɔ dɛn, yu si wan brayt layt . Wit nyu teknɔlɔji, yu kin gɛt rili klia, ay-rɛzolushɔn dijital pikchɔ dɛn. Sɔm kamɛra dɛn kin tek bɔku say na yu fundus, ɔ fɔ si tin dɛn we yu de si na di say dɛn we yu de si . Dis kin mek dɔktɔ dɛn ebul fɔ si wan big say na yu retina wan tɛm. Wan pan di big bɛnifit dɛn we dis we ya gɛt na dat i kin si yu blɔd vesel dɛn klia wan . Dis kin rili ɛp fɔ no tin dɛm lɛk dayabitis-rilayt retinopathy, we kin pwɛl di retina.

2. Wetin na Optik Kɔhɛrɛns Tomografi (OCT)?

Dis na tɛst bak we bɔku pipul dɛn kin du. i de tek kכros-sekshכn fכ si di layεr dεm na yu rεtina, spεshal wan di makula εn optik nεv. dis de mek yu si εvri layεr na di rεtina sεparat wan εn mεzj in tik. Dis impɔtant fɔ no di kɔndishɔn dɛn lɛk di makula ɛdima we gɛt fɔ du wit dayabitis ɛn di makyula dijɛnɛreshɔn.

I nɔ mata us we yu yuz fɔ dis tɛst, ɔl wetin yu fɔ du na fɔ sidɔm fayn fayn wan na chia ɛn put yu fes nia di kamɛra. Di dɔktɔ ɔ ɔda pɔsin go sho yu usay fɔ put yu fɔrɛst ɛn yu chin. Di tin we impɔtant pas ɔl na fɔ mek natin nɔ go insay yu yay we yu de du dis tɛst.

Sɔntɛnde, dɔktɔ dɛn kin yuz wan ɔ mɔ pan di we dɛn we wi dɔn tɔk bɔt di sem tɛm. כ, dεn kin du כda spεshal tεst bak we dεn kכl `fluorescein angiography` wit dis mεtכd. Insay dis, dɛn kin put smɔl day insay wan vein na yu an. Dis day de travul wit yu blɔd to di blɔd vesel dɛn we de insay yu yay. Dɔn dis kin si klia wan if ɛni blɔk ɔ ɔda prɔblɛm de na dɛn vessel dɛn de. Dis na smɔl tin bak we nɔ de ambɔg yu yay.

Wetin kin apin bifo di tɛst?

Fɔs, di dɔktɔ go ɛksplen to yu bɔt dis tɛst ɛn wetin mek dɛn de du am fɔ yu. I kin aks bak fɔ mek yu gri ɛn mek yu sayn.

Bɔku tɛm, dɔktɔ dɛn kin put drɔp na yu yay fɔ mek di yay dɛn big.. Di rizin fɔ dis na bikɔs di kamɛra kin tek pikchɔ dɛn insay di yay, lɛk winda we dɛn kɔl blak ayris, ɛn we dɛn mek am big, yu kin tek klia pikchɔ dɛn. If yu tek dis mɛrɛsin, yu fɔ rili mek pɔsin kɛr yu go na os. Bikɔs yu yay go blɔk smɔl ɛn yu go fil lɛk se yu de na do, yu nɔ go ebul fɔ drayv fɔ sɔm awa.

Wetin kin apin we dɛn de du di tɛst?

infakt, di tu `(Retinal imaging)` tεst dεm, we na `fundus photography` εn `OCT`, na kwik εn nכ de pen . Na dis na wetin kin apin:

• Yu go sidɔm na chia bifo di mashin we dɛn de yuz fɔ mek pikchɔ. Di dɔktɔ ɔ pɔsin we de ɛp yu go ɛp yu fɔ fil fayn.
• Yu nid fɔ put yu chin na say we dɛn mek fɔ am, ɛn shep yu fes so dat yu fɔɛd go pres jisnɔ pan wan smɔl bar.
• Di dɔktɔ kin ajɔst di kamɛra fayn fayn wan ɛn bigin fɔ tek pikchɔ dɛn. I kin tek pikchɔ dɛn fɔ wan yay wan bay wan.
• Dɛn kin aks yu fɔ luk wan grɛn layt . Di layt brayt smɔl, so yu kin fil bad smɔl, bɔt na fɔ shɔt tɛm nɔmɔ.
• We yu dɔn fɔ tek pikchɔ, dɛn go aks yu fɔ step away frɔm di kamɛra.

כltεm, dis `(Retinal imaging)` tεst de tek lεk 5 to 10 minit . כltu, if di dכkta du `fluorescein angiography` tεst bak, i kin tek lεk 30 minit.

Aw yu kin fil afta di tɛst?

If di dɔktɔ dɔn injekt mɛrɛsin na yu yay ɛn mek yu blak yay big, yu yay go blɔk ɛn fil fɔ sɔm awa. So, gi yu yay sɔm rɛst. Nɔ drayv, rid, ɔ luk yu fon ɔ kɔmpyuta. I fayn fɔ mek yu yay wɛr sanglas we yu de go na do.
