17. A method of estimating a pressure in a subject, comprising:
- imaging an intraocular blood vessel while applying a force to the subject'"'"'s ocular globe,the force being applied through a component having a contact surface that osculates a portion of the subject'"'"'s ocular globe,the force being sufficient to collapse an intraocular blood vessel.

Abstract
Provided are systems and methods for noninvasively assessing intracranial pressure by controllably osculating at least a portion of a subject'"'"'s ocular globe while applying a force sufficient to collapse an intraocular blood vessel and correlating the collapse pressure to intracranial pressure. Also provided are ophthalmic components useful in ophthalmic imaging applications, such as retinal, corneal, and pupil imaging. The components may include an optical contact surface that has a radius of curvature that is greater than the radius of curvature of a subject'"'"'s cornea.

35-1. The system of claim 31, wherein the component comprises a reflective portion adapted to deflect when the osculating optical surface of the component is exerted against a subject'"'"'s ocular globe.
-
36-2. The system of claim 35, further comprising a device configured to illuminate the reflective portion.
-
37-3. The system of claim 35, wherein the system is configured to measure radiation reflected from the reflective portion of the component, to measure a change in radiation reflected from the reflective portion of the component, or both.
