Theses & Dissertations
The optic nerve head (ONH) is located at the interface of intracranial and intraocular compartments. It is comprised of lamina cribrosa (LC), a fenestrated connective tissue tethered to the posterior sclera across the scleral canal. Since LC is exposed to intraocular pressure (IOP) anteriorly and intracranial pressure (ICP) posteriorly, it is an ideal site for noninvasively detecting intracranial pressure (ICP) fluctuation. We hypothesized that the pressure differential between IOP and ICP across LC, will determine LC position and meridional diameter of scleral canal (also called Bruch’s membrane opening- BMOD). We tested our hypothesis in 19 human subjects undergoing medically necessary …
