    Abstract: Eyelid illumination systems and methods for imaging meibomian glands for meibomian gland analysis are disclosed. In one embodiment, a patient's eyelid is IR trans-illuminated with an infrared (IR) light. A trans-illumination image of the patient's eyelid is captured showing meibomian glands in dark outlined areas, whereas non-gland material is shown in light areas. This provides a high contrast image of the meibomian glands that is X-ray like. The lid trans-illumination image of the meibomian glands can be analyzed to determine to diagnose the meibomian glands in the patient's eyelid. The eyelid may be trans-illuminated by a lid-flipping device configured to grasp and flip the eyelid for imaging the interior surface of the eyelid. Also, an IR surface meibography image of the meibomian glands may also be captured and combined with the trans-illumination image of the meibomian glands to provide a higher contrast image of the meibomian glands.

    Abstract: An apparatus providing heat for treatment of an eyelid includes a heater unit configured to apply heat directly to an outer surface of the eyelid when an electrical signal is applied to the heater unit. The heater unit is affixed directly to the outer surface of the eyelid using an adhesive. A temperature regulator applies the electrical signal to the heater unit in order to achieve heating of the outer surface of the eyelid to a specified temperature range. A method is also disclosed that comprises affixing a heater unit directly into contact with the outer surface of the eyelid using an the adhesive. A control signal is applied to the heater unit to generate heat to the outer surface of the eyelid and is maintained for a period of time until the outer surface of the eyelid is heated to a specified temperature range.

    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 lipid layer thickness (LLT) and/or aqueous layer thickness (ALT). The measured TFLT can be used to diagnosis dry eye syndrome (DES). In certain disclosed embodiments, a multi-wavelength light source can be controlled to illuminate the ocular tear film. Light emitted from the multi-wavelength light source undergoes optical wave interference interactions in the tear film. An imaging device can be focused on the lipid layer of the tear film to capture optical wave interference interactions of specularly reflected light from the tear film combined with a background signal(s) in a first image. The imaging device can also be focused on the lipid layer of the tear film to capture a second image containing the background signal(s) present in the first image. The second image can be subtracted from the first image to reduce and/or eliminate the background signal(s) in the first image to produce a resulting image. The resulting image can be processed and analyzed to measure a tear film layer thickness (TFLT), including lipid layer thickness (LLT) and/or aqueous layer thickness (ALT).

    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.

    Abstract: A method of treating dry eye includes delivering light energy from outside an eyelid toward the eyelid, and maintaining the delivery of the light energy toward the eyelid for a period of time sufficient to soften an obstruction of at least one meibomian gland. The light energy may be delivered specifically to the obstruction within the at least one meibomian gland without physically contacting the at least one meibomian gland, or the light energy delivered toward the eyelid may conductively apply heat to the meibomain gland sufficient to melt the obstruction. A corresponding apparatus includes a light energy source positionable outside an eyelid and configured to deliver the light energy from outside an eyelid toward the eyelid, and a controller configured to control the light energy source to maintain the delivery of the light energy toward the eyelid for a period of time sufficient to soften the obstruction.
