Computer-assisted analysis of meibomian gland (MG) morphology.

<p>The MG length, thickness, and gap are marked as thick yellow line, green line, and red lines, respectively. The photos in the left column show MG loss in the upper eyelids of three eyes of 58.2%, 57.8%, and 67.9%, from top to bottom, respectively, whereas the photos in the right column show MG loss in the lower eyelids of the same eyes of 58.6%, 47.1%, and 64.9%, from top to bottom, respectively.
