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):
A method of imaging an eye, comprising:\n modulating light from a multi-wavelength light source to project the light onto the eye; receiving at an imaging device, at least one first image comprising at least one first signal associated with an ocular property of the eye comprising a first pattern of optical wave interference of specularly reflected light and at least one background signal from at least one first portion of an ocular tear film of the eye, and a second pattern of optical wave interference of specularly reflected light and the at least one background signal from at least one second portion of the ocular tear film different from the at least one first portion; modulating light from the multi-wavelength light source to project a second light onto the eye; and receiving at the imaging device, at least one second image containing at least one second signal associated with the ocular property of the eye comprising optical wave interference of specularly reflected second light including at least one second background signal reflected from the at least one second portion of the eye different from the at least one first portion of the eye.
