Aw dɛn kin du dis tɛst? Yu tink se i at lɛk aw yu tink?
Nɔto so atɔl! OCT skan na simpul tin we nɔ de mek pɔsin fil pen ɛn i kin dɔn insay sɔm minit . I nɔ nid ɛni spɛshal pripiamɛnt ɔ fɔ stɔp fɔ it. Yu kin ivin du am jɔs afta yu de chɛk yu yay ɔltɛm.
Na dis na wetin kin apin stɛp bay stɛp:
1. Dilayt: Sɔntɛnde, fɔ mek yu gɛt klia pikchɔ dɛn bɔt di insay pat pan yu yay, yu dɔktɔ go put ay drɔp na yu yay fɔ mek di pupil dilayt. Nɔto ɔltɛm dis kin nid fɔ apin.
2. Sidɔm bifo di mashin: Dɔn yu go sidɔm na chia bifo di OCT skan. Dɛn go put yu chin ɛn fɔrɛst pan sɔpɔt we dɛn tay pan di mashin. Dis go ɛp fɔ mek yu ed stil ɛn nɔ muf.
3. Fɔ luk wan ples: Neks, dɛn go aks yu fɔ luk wan smɔl grɔn layt insay di mashin we yu nɔ blink.

Ɛni sayd ɛfɛkt de frɔm di OCT tɛst?
Dis na di bɛst tin. No risk ɔ sayd ɛfɛkt nɔ de fɔ di ɛgzam we dɛn du wit di OCT skan. I de 100% sef.
Bɔt lɛk aw wi bin dɔn tɔk, if yu yuz ay drɔp fɔ mek yu blak yay big bifo yu du di tɛst, i kin mek yu nɔ fil fayn fɔ sɔm tɛm.

If yu dɔn du OCT tɛst bifo, yu dɔktɔ go kɔmpia di nyu pikchɔ dɛn wit di ol wan dɛn. Dis go ɛp yu fɔ no kɔrɛkt wan aw yu sik dɔn chenj as tɛm de go (i dɔn wɔs, i dɔn bɛtɛ, ɔr i dɔn de di sem).
Afta we di dɔktɔ dɔn stɔdi di tin dɛn we dɔn apin, i go ɛksplen to yu bɔt di tin we apin. Bay di rizɔlt fɔ dis tɛst, dɛn go disayd bɔt di tritmɛnt we yu go gɛt tumara bambay ɛn if yu nid fɔ chenj di tritmɛnt we yu gɛt naw.
Ustɛm a fɔ go to di dɔktɔ?
Nɔ ɛva skip yu ay ɛgzam ɔltɛm. Dis kin ɛp yu fɔ kech bɔku siriɔs prɔblɛm dɛn kwik kwik wan. Apat frɔm dat, if yu si ɛni wan pan di sayn dɛn we de dɔŋ ya, go to yu dɔktɔ wantɛm wantɛm.
