Abstract

See full text

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.
