Modified meibography in malignant eyelid tumors of epithelial origin
Vestnik oftal'mologii, 2019Eyelid tumors can be diagnosed using various diagnostic techniques. However, capability of existing methods for determining the type and margins of the tumor at the preoperative stage remains insufficiently studied.To improve the noncontact infrared meibography technique and determine its diagnostic capabilities for studying structural changes in ...

Automatic Lid Segmentation in Meibography Images
2019This work presents an evaluation of two machine learning schemes for lid segmentation on meibography images. Both schemes use same input features based on pixel gray levels, laplacian and entropy filters, and also distances to anatomical landmarks like pupil and eye lashes.

Meibography of the Upper Eyelids in Cats. Correlations With Age, Body Weight and Tear Parameters
Anatomia, Histologia, Embryologia. Journal of Veterinary Medicine Series CMeibomian glands are responsible for the production and secretion of lipids into the precorneal tear film, which limits its evaporation. This study aimed to evaluate the percentage of Meibomian gland loss rate (MGLR) in the upper eyelid of cats of ...
