    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: Methods and apparatuses for determining contact lens intolerance in contact lens wearer patients based on tear film characteristics analysis and dry eye symptoms are disclosed. In embodiments herein, imaging of the ocular tear film is performed during contact lens wear. An analysis of the image of the ocular tear film is performed to determine one or more tear film characteristics of the ocular tear film. The tear film characteristics can be used to determine the effect or possible effect of contact lens wear on the ocular tear film, and thus be used to determine contact lens intolerance of the patient. The tear film characteristics used to analyze contact lens intolerance based on images of the ocular tear film involving contact lens wear may include dry eye symptoms, including but not limited to tear film (e.g., lipid and/or aqueous) thickness, tear film viscosity, and tear film movement rate in the eye.
