Fig 1. Enhanced depth imaging OCT image and converted binary image of the eye of a glaucoma patient.

The EDI-OCT images in the macular area (A) or the peripapillary area (C) were converted to binary images (B, D) using the ImageJ software. The luminal area (dark area) and the interstitial area are seen. The area between the blues lines indicates the measurement area of the choroid.
