Applicability of Novel Laser Scanning Microscopy Techniques in Demonstrating Characteristic Features of Porokeratosis: In Vivo and Ex Vivo Investigation

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Porokeratoses represent a group of keratinization disorders characterized histopathologically by the presence of a cornoid lamella. The recognition of porokeratosis as a genodermatosis, along with its association with increased risk of skin cancer, underscores the importance of accurate and timely diagnosis.

Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging in Vivo

open access: yesLaser &Photonics Reviews, EarlyView.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...
