Meibography is used to image which ocular structure?

• A. Cornea
• B. Lens
• C. Meibomian glands
• D. Retina

Answer: (C)

Meibography is imaging designed to visualize the Meibomian glands, which sit in the eyelid tarsal plates and produce the lipid layer of the tear film. Using infrared light, this method images the glands through the eyelids to assess their appearance, including dropout, atrophy, or distortion that can occur with meibomian gland dysfunction. This is particularly helpful for diagnosing evaporative dry eye related to MG dysfunction. The cornea, lens, and retina are examined with other modalities or structural assessments (such as slit-lamp examination with corneal assessment, lens imaging, or retinal fundus imaging), not with meibography. Therefore, the structure specifically imaged by meibography is the Meibomian glands.
