Telomerase Immortalization of Human Corneal Endothelial Cells Yields Functional Hexagonal Monolayers [PDF]

, 2012
Human corneal endothelial cells (HCEnCs) form a monolayer of hexagonal cells whose main function is to maintain corneal clarity by regulating corneal hydration. HCEnCs are derived from neural crest and are arrested in the post-mitotic state.

Stromal Curvature, Power and Corneal‐Stromal Curvature Ratios From a Hybrid AS‐OCT in Eyes With Keratoconus

Clinical &Experimental Ophthalmology, Volume 54, Issue 1, Page 9-20, January/February 2026.
ABSTRACT Background To characterise stromal curvature and curvature ratios in keratoconus (KCN) using anterior segment OCT, and to evaluate the implications of using single‐, two‐, and three‐surface refractive models for corneal power estimation in ectatic eyes. Methods Retrospective observational study.

Evolution of Ocular Organ‐On‐Chip Systems for Disease Modelling and Drug Testing: Where are We Now?

Advanced Therapeutics, Volume 8, Issue 9, September 2025.
The rise in ophthalmic diseases due to aging, screen use, and environmental factors has driven demand for better ocular models. Traditional systems fall short, encouraging the development of organ‐on‐chip devices. These microfluidic platforms replicate eye tissue architecture, enable drug screening, and simulate ocular diseases.

Biocompatibility of Genetically‐Engineered Pig Cornea in Corneal Xenotransplantation: Preliminary In Vitro Study

Xenotransplantation, Volume 32, Issue 5, September/October 2025.
ABSTRACT Introduction We aimed to evaluate biophysical compatibility of corneal endothelial cells in genetically‐engineered (GE) pigs to identify the best candidate for in vivo nonhuman primate (NHP) study and to collect baseline data for future clinical trials from a biological function perspective.

Corneal amyloid staining after trypan blue in Descemet's membrane endothelial keratoplasty

American Journal of Ophthalmology Case Reports
Purpose: This case report seeks to highlight impressive photographs of amyloid staining with trypan blue that persisted after DMEK surgery with 3 years follow-up. This has only been reported in the literature twice previously, and may have contributed to
