Detection of meibomian glands and classification of meibography images.
Computational methods are presented that can automatically detect the length and width of meibomian glands imaged by infrared meibography without requiring any input from the user. The images are then automatically classified. The length of the glands are detected by first normalizing the pixel intensity, extracting stationary points, and then applying morphological operations. Gland widths are detected using
Do you remember when the term "Non Obvious MGD" emerged?
Well, here's a new term for its counterpart. Dr. Suzuki of Kyoto Pref. U. has coined the elegant, dignified term Meibomitis Related KeratoConjunctivitis (MRKC). Though personally I'd prefer to stick with what I've always used: Obvious MGD. Kind of a nice ring to it, wouldn't you say?
I can just hear the conversations now.
"Well," (snickers the patient during a visit to
Lid margins: sensitivity, staining, meibomian gland dysfunction, and symptoms.
PURPOSE.: Ocular surface sensitivity plays a role in dry eye and ocular comfort through its probable influence on the neural feedback loop that regulates tear secretion, but little is known specifically about the role of lid or lid margin sensitivity in ocular surface health. The aim of this study was to characterize the eyelid margin and explore the relationships between lid margin sensitivity and staining,
Kind of a nice blurb summarizing some barebones facts most of us know :-)
[Meibomian gland dysfunction]. [Article in German]
Meibomian gland dysfunction (MGD) is a chronic disease, usually caused by obstruction of the secretory Meibomian glands. The subsequent reduction of gland secretion results in a decreased amount of lipids in the tear film. This results in a faster evaporation of the tear film and thus an evaporative dry eye. MGD alone is responsible for about
Quantification of human sebum on skin and human meibum on the eye lid margin using Sebutape®, spectroscopy and chemical analysis.
The purpose of this study was to determine if the variability in the amount of lid margin meibum is from donor-to-donor or from day-to-day variations and to determine if meibum from donors with meibomian gland dysfunction (MGD) had altered levels of casual eyelid meibum or skin sebum.
