Is histogram manipulation always beneficial when trying to improve model performance across devices? Experiments using a Meibomian gland segmentation model

Frontiers in Cell and Developmental Biology, 2022
Meibomian gland dysfunction (MGD) is caused by abnormalities of the meibomian glands (MG) and is one of the causes of evaporative dry eye (DED). Precise MG segmentation is crucial for MGD-related DED diagnosis because the morphological parameters of MG ...

Plexiform Neurofibroma With Activating KRAS Mutation and Segmental Presentation Involving the Unilateral Eyelid

Ophthalmic Plastic & Reconstructive Surgery, 2022
Plexiform neurofibromas are classically thought to be pathognomonic for neurofibromatosis type 1. However, isolated forms may occur, particularly as a manifestation of segmental neurofibromatosis related to postzygotic mosaicism in the NF1 gene.
