Non-contact meibography. a Non-contact infrared meibography of an upper eyelid with normal meibomian glands. b An upper eyelid affected by MGD. The eyelid margin is characterized by diffused ductal occlusion and plugging of the MGs orifices (dotted arrows). The eyelid mucocutaneous junction is moved posteriorly with retroplacement of ductal openings (multiple arrows). Areas characterized by cystic dilatation of the ducts filled with extremely dense opaque secretion (black arrows and ovals) alternate with darker areas due to the diffused atrophy of the acini detected as gland dropout on infrared meibography (white ovals)
