1 point

Any boundary detection error (deviation of at least 4×10 pixels [height x width])

1 point

Any boundary detection error within the area of the fovea (central 1 mm of the 5 mm long scan)

1 point

The sum of horizontal errors exceeds 1 mm

1 point

The sum of horizontal errors exceeds 3 mm

1 point

The sum of vertical errors exceeds 1/3 of total retinal thickness

1 point

The sum of vertical errors exceeds 1/3 of total retinal thickness
