Spectralis OCT at baseline and 3 months after treatment. Subfoveal choroidal thickness (SFCT) and 1500 mu temporal and nasally measured vertically from the outer border of the RPE to the inner border of the sclera in micrometers (Figure 1).
The fovea avascular zone (FAZ) area has been manually plotted using the polygon selection tool in the superficial capillary plexus (SCP) and its dimension is reported in square micrometers. The end tip vessels at SCP were manually marked and these areas were connected and the area of the central area was calculated by the device.

The fovea avascular zone (FAZ) area has been manually plotted using the polygon selection tool in SCP and its dimension in square micrometers has been calculated (Figure 2).
Vessel density at SCP was automatically calculated by the device and reported as a percentage in the central area and four quadrants (superior, nasal, temporal, and inferior). Areas with blood vessels and flow are shown in warm colors (red) and areas without blood vessels are shown in cold colors (blue).

Vessel density at SCP and choriocapillaris layer was automatically calculated by the device and reported as a percentage in the central area and four quadrants (Figure 3).
