Wide-field en-face SS-OCT image of the inner limiting membrane, showing our method to measure the RNFLD angle.
A: Original B-scan image with the ILM highlighted in green. B: The image aligned to the ILM. C: Method of measuring the angle of the RNFLD in the en-face flattened image.
Fig 2.
RNFLD angle in different layers.
En-face images of horizontal planes at different depths below the ILM, and measurement of the RNFLD angle in each image. (A) En-face image 1 was averaged from the ILM plane down to 18.2 μm. (B) En-face image 2 was averaged at the range of 20.8 to 36.4 μm from ILM plane. (C) En-face image 3 was averaged at the range of 39.0 to 54.6 μm from ILM plane. (D) Boxplot showing the RNFLD angle in each en-face image. Boxplot is of RNFLD angles for each depth across the entire population.
