A method of trans-illuminating a meibomian gland in an eyelid of a patient to image the meibomian gland, comprising: directing a first infrared light from a first IR light source to the eyelid (22, 24) to IR trans-illuminate meibomian glands in the eyelid; imaging the eyelid with an imaging device during IR trans-illumination to produce an IR trans-illumination image of the meibomian glands in the eyelid; receiving the IR trans-illumination image of the eyelid at a computer control system associated with the imaging device; storing the IR trans-illumination image in a memory associated with the imaging device, the method being characterized in further comprising: directing a second IR light from a second IR light source to an interior portion of an interior surface of the eyelid to surface illuminate the interior portion of the interior surface of the eyelid; imaging the interior portion of the interior surface of the eyelid with the imaging device when the interior portion is illuminated with the second IR light to produce a surface meibography image of the meibomian glands in the eyelid; and combining the IR trans-illumination image and the surface meibography image to produce a resultant image, wherein directing the first IR light from the first IR light source to the eyelid comprises directing the first IR light from the first IR light source to an exterior portion of an exterior surface of the eyelid to IR trans-illuminate the meibomian glands in the eyelid, and wherein imaging the eyelid with the imaging device during IR trans-illumination comprises imaging the interior portion of the interior surface of the eyelid with the imaging device during IR trans-illumination to produce the IR trans-illumination image of the meibomian glands in the eyelid, the method further comprising flipping the eyelid to expose the interior portion of the interior surface of the eyelid to an imaging path of the imaging device; wherein imaging the interior portion of the interior surface of the eyelid with the imaging device during IR trans-illumination is performed when the eyelid is flipped. directing a first infrared light from a first IR light source to the eyelid (22, 24) to IR trans-illuminate meibomian glands in the eyelid;
