Check image quality.

Check continuous OCT image continuously by pressing play image icon ( ) if needed.
③ Check SSI for image quality if needed.
SSI (Scan Signal Index) indicates level of image quality. SSI means signal to background ratio and
displayed on a scale of 10 with a bar graph. SSI larger than 8 means ‘Good’, 5~8 means ‘Normal’,
less than 5 means ‘Poor’ in general.
We recommend capture normal or good status in general. But, you don’t have to retry when image is
satisfactory but SSI is low, because SSI depends on patient’s eye conditions.
