OSDx test
Meibography
Meibography uses near-infrared imaging to document meibomian gland structure and quantify gland-area loss.
It complements lipimetry by assessing the glandular source of the tear-film lipid layer.
What OSDx measures
OSDx images the upper and lower lids with near-infrared illumination. The structure of the ducts and acini
can be reviewed, and the report provides quantitative gland-area information.
- Meibomian gland area.
- Gland loss percentage.
- Image-enhancement and segmentation tools for gland visualisation.
- Upper and lower lid documentation for each eye.
Clinical relevance
Meibography helps document gland dropout, altered gland morphology and changes associated with meibomian
gland dysfunction. It is especially useful when reviewed together with lipid-layer thickness and lid-margin findings.
