The Difference in Translaminar Pressure Gradient and Neuroretinal Rim Area in Glaucoma and Healthy Subjects

Figure 2

Noninvasive intracranial pressure absolute value measurement procedure. Time diagram of the externally applied pressure Pe(𝑡) when pressure step is equal to 2 mmHg (solid black step function) and intracranial pressure ICP(𝑡) (thin green line). Point (A) is pressure balance Pe = aICP point when pressure step is equal to 2 mmHg, respectively.
