Abstract:
Ocular surface interferometry (OSI) devices, systems, and methods are disclosed for measuring a tear film layer thickness (TFLT) of the ocular tear film, including the lipid layer thickness (LLT) and/or the aqueous layer thickness (ALT). The TFLT can be used to diagnose dry eye syndrome (DES). Certain embodiments also include ocular topography devices, systems and methods for deducing corneal shape by capturing an image of a target reflecting from the surface of the cornea. The image of the target contains topography information that is reviewable by a clinician to diagnose the health of the patient's eye by detecting corneal aberrations and/or abnormalities in corneal shape. Certain embodiments also include a combination of the OSI and ocular topography devices, systems and methods to provide imaging that can be used to yield a combined diagnosis of the patient's tear film and corneal shape.

Claim (Index 1):
An apparatus for imaging an eye, comprising:\n a control system configured to:\n (a) modulate light from a multi-wavelength light source to project a first pattern onto the eye; \n (b) receive at an imaging device, at least one first image containing at least one first signal associated with an ocular property of the eye comprising emitted light reflected from at least one first portion of the eye; \n (c) modulate light from the multi-wavelength light source to project a second pattern onto the eye, such that at least one second portion of the eye receives the emitted light from the multi-wavelength light source; and \n (d) receive at the imaging device, at least one second image containing at least one second signal associated with the ocular property of the eye comprising the emitted light reflected from the at least one second portion of the eye; \n wherein:\n the at least one first signal is optical wave interference of specularly reflected light from an ocular tear film combined with at least one background signal; and \n the control system is configured to receive the at least one first image by being configured to:\n capture a first pattern of the specularly reflected light including the at least one background signal from the at least one first portion of the ocular tear film in the at least one first image by the imaging device; and \n capture a second pattern of the specularly reflected light including the at least one background signal from the at least one second portion of the ocular tear film in the at least one second image by the imaging device.
