The relationship between chronic ICP and BM margin displacement into the globe. ICP was measured by LP opening pressure performed less than 1 hour following OCT imaging. BM margin displacement was calculated relative to a secant line connecting BM points 1540 μm on either side of the optic nerve head on OCT B-scan of each optic nerve head. Negative values represent location posterior to the reference line. Markers represent temporal (open) and nasal (closed) displacements in 39 eyes in 20 participants.
