Evaluating anterior corneal surface using Placido ring mires for irregular astigmatism in refractory corneal subepithelial infiltrates after adenoviral conjunctivitis

BMC Ophthalmology
Background Corneal subepithelial infiltrates (SEIs) are characteristic clinical findings of adenoviral keratoconjunctivitis (AKC). In eyes with SEIs, both corneal opacity and irregular astigmatism may interfere with vision. However, irregular astigmatism

Learning to Segment Corneal Tissue Interfaces in OCT Images [PDF]

arXiv, 2018
Accurate and repeatable delineation of corneal tissue interfaces is necessary for surgical planning during anterior segment interventions, such as Keratoplasty. Designing an approach to identify interfaces, which generalizes to datasets acquired from different Optical Coherence Tomographic (OCT) scanners, is paramount.

How to Study the Mechanobiology of Intestinal Epithelial Organoids? A Review of Culture Supports, Imaging Techniques, and Analysis Methods

Biology of the Cell, Volume 117, Issue 4, April 2025.
Mechanical forces can influence biological processes in both healthy and pathological contexts. Organoids are 3D structures derived from stem cells that can be used to model tissues and organs in vitro. The objective of this review is to present the different ways to culture and observe organoids under a microscope to study mechanical interactions in ...
