An adaptive algorithm for the cornea modeling from keratometric data [PDF]
, 2010 In this paper we describe an adaptive and multi-scale algorithm for the parsimonious fit of the corneal surface data that allows to adapt the number of functions used in the reconstruction to the conditions of each cornea. The method implements also a dynamical selection of the parameters and the management of noise.

Elongated Physiological Structure Segmentation via Spatial and Scale Uncertainty-aware Network [PDF]
arXiv, 2023 Robust and accurate segmentation for elongated physiological structures is challenging, especially in the ambiguous region, such as the corneal endothelium microscope image with uneven illumination or the fundus image with disease interference. In this paper, we present a spatial and scale uncertainty-aware network (SSU-Net) that fully uses both ...

Managing ocular surface disease: a common sense approach
Community Eye Health Journal, 2017 Many diseases can cause ocular surface disorders. The poster on pages 50–51 provides an overview of the most common diseases, and other articles in this issue focus on the management of individual diseases. In this article, the authors offer a systematic

Advanced Healthcare Materials, Volume 14, Issue 9, April 4, 2025.This study optimizes sterilization methods for bioprinted 3D corneal stroma patches made from cornea‐derived decellularized extracellular matrix (Co‐dECM) hydrogels and human keratocytes. It demonstrates the superiority of electron beam sterilization in preserving the mechanical, biochemical, and immunomodulatory properties of hydrogels, ensuring ...

The elusive scleral cartilages: Comparative anatomy and development in teleosts and avians
The Anatomical Record, EarlyView., 2023 Abstract The sclera of all vertebrate eyes is comprised of connective tissue, with some organisms developing cartilage within this tissue. A review of the cartilages that have been described in the vertebrate sclera and their anatomical relationships is discussed together with their potential homology.

Overexpression of MMPs in Corneas Requiring Penetrating and Deep Anterior Lamellar Keratoplasty. [PDF]
, 2019 PurposeMatrix metalloproteinases (MMPs) comprise a family of zinc-dependent endopeptidases involved in wound healing processes, including neovascularization and fibrosis. We assessed MMP protein expression levels in diseased corneas of patients requiring

Advanced Healthcare Materials, EarlyView.Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Corneal Pachymetry by AS-OCT after Descemet's Membrane Endothelial Keratoplasty [PDF]
arXiv, 2021 Corneal thickness (pachymetry) maps can be used to monitor restoration of corneal endothelial function, for example after Descemet's membrane endothelial keratoplasty (DMEK). Automated delineation of the corneal interfaces in anterior segment optical coherence tomography (AS-OCT) can be challenging for corneas that are irregularly shaped due to ...

Limbal stem cell transplantation: clinical results, limits, and perspectives [PDF]
, 2018 Limbal stem cell deficiency (LSCD) is a clinical condition characterized by damage of cornea limbal stem cells, which results in an impairment of corneal epithelium turnover and in an invasion of the cornea by the conjunctival epithelium.
