Wan impɔtant pat pan ay ɛgzam: Lɛ wi lan bɔt Retinoscopy.

Yu dɔn ɛva du ɛgzam fɔ yu yay? Ɔ yu dɔn ɛva kɛr yu smɔl pikin go to dɔktɔ we de mɛn yu yay? Da tɛm de, yu kin dɔn yɛri di wɔd ‘rɛtinoskɔpi’. Dis na rili impɔtant tin fɔ du fɔ chɛk yu yay. Tide, wi go tɔk bɔt wetin na dis retinoscopy, wetin i de du, ɛn aw i impɔtant.

Wetin na Retinoskopi?

Fɔ tɔk am simpul wan, retinoskopi na spɛshal tɛst we dɔktɔ we de mɛn yu yay kin yuz fɔ no di rayt we aw yu de si, ɔ di mistek dɛn we yu de si, ɔ di mistek dɛn we yu de si. Dɛn kin yuz spɛshal inschrumɛnt we dɛn kin ol wit an ɛn layt fɔ du dis. Dis layt de sɛn insay yu yay, usay i de nak di retina we de biɛn yu yay, ɛn i de riflɛkt bak.

Pan ɔl we bɔku nyu we dɛn de fɔ chɛk di yay dɛn tɛm ya, dɛn stil rili pɔpul dis we we dɛn kɔl retinoscopy. Bɔku tɛm dɛn kin du am as pat pan di rutin ay ɛgzam.

Dis we ya impɔtant mɔ fɔ chɛk di wan dɛn we nɔ ebul fɔ tɛl di dɔktɔ bɔt dɛn prɔblɛm dɛn yay. Imajin, aw smɔl bebi go tɛl yu bɔt di we aw i de si?

Bak:

• Fɔ pikin dɛn we rili yɔŋ (ivin frɔm we dɛn bɔn dɛn) .
• Fɔ di wan dɛn we nɔ ɔndastand di langwej we di dɔktɔ de tɔk ɛn we gɛt langwej barɛri
• Fɔ di wan dɛn we gɛt prɔblɛm wit dɛn maynd
• Dis tɛst impɔtant we i kam pan fɔ gi ayglas to pipul dɛm wae gɛt prɔblɛm wit dɛn bren wae gɛt fɔ du wit dɛn ej (e.g. dimɛnshɔn) .

Wan ɔda tin na dat wan spɛshal we we dɛn kɔl retinoscopy kin no bak if yu yay gɛt prɔblɛm fɔ pe atɛnshɔn pan difrɛn distans.

Aw dis kin wok?

Okay, naw mek wi si aw dis retinoscopy test de wok. We layt kam insay yu yay, i kin pas tru di kɔnia ɛn di lens we de insay di yay, ɛn i kin nak di retina we de biɛn di yay. Dɔn di layt kin kɔmɔt bak, jɔs lɛk aw layt kin kɔmɔt na miro.

Dis layt we de riflekt de mek di pupil na yu yay tan lɛk rɛd, ɔ i de shayn. Dɔktɔ dɛn kin kɔl dis di `Fundus reflex` ɔ `Red reflex` . Yu go dɔn notis se sɔntɛnde we yu tek foto, yu yay kin luk rɛd, na dat kin apin.

Tipikli, wan ay egzam go mek yu no aw yu de si fayn, we na aw yu de si 20/20 . 20/20 vishכn na di lεvεl we tu hεlty yay dεm kin si klia wan. pan pכsin we gεt dis lεvεl fכ si, di layt rayt dεm we de kכmכt frכm di rεtina fכ de paralel we i de kכmכt na di yay.

Bɔt if yu gɛt rifraktiv mistek – yu de si nia, yu de si fa, ɔ yu astigmatism – dɛn layt rayt ya kin bɛn ɛn nɔ kin kɔmɔt na wan stret layn. Na da tɛm de di ɔftalmolɔg de yuz rɛtinoskɔpi fɔ si us kayn lens go mek dɛn layt rayt ya kɔmɔt paralel. Dat kɔrɛkshɔn na wetin yu prɛskrishɔn bi. Dɔn gɛt am?

Us kɔndishɔn dɛn kin no wit rɛtinoskɔpi?

Dis rεtinoskopi tεst kin εp bak fכ no sכm כda ay kכndyushכn dεm. Fɔ ɛgzampul:

• Amblyopia: Dɛn kin kɔl dis bak "lɛs yay." Na wan sik we wan yay nɔ kin si bɛtɛ pas di ɔda wan. If dɛn no am kwik, dɛn kin trit am.
• Presbyopia: Dis na wan sik wae kin apun to bɔrku pipul wae dɔn pas 40 ia .
• Strabismus: Dis na wetin wi kɔl krɔs-ay . Na we dɛn tɔn di yay dɛn to difrɛn say dɛn instead fɔ pɔynt dɛn na di sem say. I impɔtant bak fɔ no dis kwik kwik wan.

Wetin fɔ ɛkspɛkt bifo di tɛst?

Bɔrku tɛm, yu nɔr nid fɔ du ɛni spɛshal tin fɔ rɛdi fɔ retinoskopi (ɔ kɔmplit ay ɛgzam we inklud dis). Bɔt sɔntɛnde, sɔm smɔl smɔl tin dɛn de we yu kin du. If ɛni wan de, yu yay dɔktɔ go tɛl yu bɔt dɛn bifo di ɛgzam. If yu wɛr kɔntakt lens, yu dɔktɔ go tɛl yu bak aw lɔng bifo di ɛgzam yu nid fɔ tek am.

Bifo yu du rutin retinoscopy, yu yay dɔktɔ go put spɛshal ay drɔp (sayklɔplejik mɛrɛsin) na yu yay. Dɛn mɛrɛsin ya kin stɔp yu yay fɔ tray fɔ ɔto-fɔkus we yu de du di ɛgzam. If dɛn du dat, i nɔ go izi fɔ mek di dɔktɔ no di nɔmba fɔ yu glas kɔrɛkt wan.

Bɔt if di dɔktɔ go du wan spɛshal tin we dɛn kɔl dinamik rɛtinoskɔpi , dɛn nɔ go put dɛn drɔp ya bifo tɛm bikɔs di tɛst dipen pan di we aw yu yay dɛn kin pe atɛnshɔn pan insɛf.

Wetin kin apin we dɛn de du di tɛst?

We dɛn de du di ɛgzam, dɛn go sidɔm yu na chia na wan rum we dak. Di dɔktɔ we de mɛn yu yay go sidɔm bifo yu. Wan pan di inschrumɛnt dɛn we dɛn go yuz na retinoscope . Dis na tin we pɔsin kin ol wit an we tan lɛk pawaful flashlayt ɛn magnifying glas we dɛn jɔyn. I kin shayn layt na yu yay ɛn tek tɛm luk am gud gud wan.

di nɛks tin we impɔtant pas ɔl na fɔ put difrɛn saiz lens dɛn ɛn luk di chenj dɛn we de apin na di layt we di pupil na yu yay de si. Tu men we dɛn de fɔ du dis:

• Fɔropta: Dis na tin we tan lɛk bɔtaflay we fit oba yu fes wit tu ol dɛn fɔ mek yu si tru. I gɛt difrɛn lens dɛn, so di dɔktɔ kin fit ɛni wan pan di glas dɛn kwik kwik wan.
• Lεns dεm we yu kin ol wit an: dεn kin kam insay di fכm fכ "lεns kad," we min se dεn kin glu εvri saiz fכ lens pan wan flat sheet. כ dεn kin kam lεk wan wan "lכs" lεns dεm. Pan ɔl we yu kin chenj di lens dɛn kwik kwik wan frɔm lens kad, we yu de yuz wan wan lens dɛn, yu fɔ rili tek tɛm we yu de put ɛni lens wan bay wan.

we di dכkta shayn layt tru dis lens insay yu yay, we dεn kכl rεtinoskop, dεn de luk fכ spεshal chenj dεm na di rεd rεflεks we de apia na yu pupil. Dɛn chenj ya na:

• Di we aw di lens de muv: Di dɔktɔ kin no if di lens na di rayt sayz, i tu smɔl, ɔ i tu big bay we i luk di we aw dis lens de muv bak ɛn biɛn.
• Angle of vision: Dis angle of vision na in de ɛp di dɔktɔ fɔ no if yu gɛt astigmatism (na wan kɔndishɔn we yu nɔ de si fayn bikɔs yu de chenj smɔl na di shep na di yay).
• Di we aw di lens de luk: We yu dɔn fɛn di rayt glas fɔ yu, di we aw dis lens de luk go chenj bak.

As di dɔktɔ de shayn layt insay yu yay tru wan lens, dɛn de muv di layt ɔp ɛn dɔŋ, lɛft ɛn rayt, ɛn krɔs bɔku tɛm. Dɛn kin chenj di lens dɛn bak we dɛn kin yuz. Dɛn kin du dis bɔku tɛm, dɛn kin stɔp af-af fɔ ajɔst di layt na di retinoskɔp, ɔ fɔ tek not.

Wetin na Daynamik Rɛtinoskɔpi?

Retinoscopy na spɛshal we fɔ chɛk yu yay fɔ si tin dɛn we de nia yu, we na fɔ tɛst aw dɛn ebul fɔ pe atɛnshɔn. Dis we aw pɔsin kin ebul fɔ pe atɛnshɔn nia, dɛn kɔl am ples fɔ slip . Dynamic Retinoscopy na wan we we ɔftalmolɔg kin yuz fɔ tɛst dis abiliti.

If yu dɔktɔ de yuz Dynamic Retinoscopy fɔ chɛk aw yu yay ebul fɔ pe atɛnshɔn, di tɛst go tan lɛk aw i bin de bifo, bɔt i nɔ go yuz magnifying lens. Bifo dat, yu dɔktɔ go tɛl yu fɔ luk tin dɛn we de fa frɔm difrɛn say dɛn. Sɔm tin dɛn go de bitwin yu ɛn di dɔktɔ, ɔda wan dɛn go de biɛn di dɔktɔ (bɔt yu kin si am frɔm di dɔktɔ in sayd ɔ oba in sholda).

We yu luk dɛn tin ya, di dɔktɔ de luk di layt we de na yu pupil tru di layt we in rɛtinoskɔp de gi. Di we aw layt de muv na aw di dɔktɔ de no if di ebul we yu yay ebul fɔ pe atɛnshɔn (kɔmod) de wok fayn fayn wan.

Wetin fɔ ɛkspɛkt afta di tɛst?

If yu dɔktɔ yuz ay drɔp (sayklɔplejik mɛrɛsin) fɔ mek yu yay big ɔ fɔ stɔp yu yay fɔ fos, yu yay go kɔntinyu fɔ dilayt fɔ sɔm tɛm afta di tɛst. Di tɛm we dɛn mɛrɛsin ya kin tek kin difrɛn. Bɔku tɛm, i kin tek sɔm awa. Yu ay spɛshal dɔktɔ go tɛl yu aw lɔng dis go las.

Yu kin si smɔl smɔl dis tɛm, ɛn yu kin fil se yu de si tin na do. So, yu dɔktɔ kin gi yu tɛmporari sanglas (`sanshades`) fɔ wɛr. Bikɔs di ay drɔp dɛn de mek yu ayris nɔ shrink we brayt layt ɛn i de mek di layt we de kam insay yu yay nɔ bɔku.

Ɛni risk de fɔ dis tɛst?
