• How long should dilating drops be in the eyes before an OCT imaging scan?


    Question:

    How long should dilating drops be in the eyes before taking optical coherence tomography (OCT) photos?


    Answer:

    OCT (an imaging test that uses light waves to take highly detailed pictures inside the eye) can be done with or without dilating drops. If drops are used, there is no certain time, but often at least 15 minutes is required.
