Modern Diagnostic Modalities for Fuchs’ Endothelial Corneal Dystrophy: A Comparative Analysis Using Scheimpflug Tomography

Medicina
Background and Objectives: Fuchs’ endothelial corneal dystrophy (FECD) is a progressive disorder characterized by endothelial cell loss, corneal edema, and reduced transparency. Scheimpflug tomography enables objective evaluation of the corneal structure,

Buyang Huanwu Decoction Alleviates Chronic Intermittent Hypoxia–Induced Myocardial Inflammation and Fibrosis via the NF‐κB/LOX Signaling Pathway

Human Mutation, Volume 2026, Issue 1, 2026.
Objective To investigate the protective effects of Buyang Huanwu decoction (BYHW) on myocardial injury induced by chronic intermittent hypoxia (CIH) in rats and to analyze its potential regulatory mechanism through the NF‐κB/LOX signaling pathway. Methods Then, 36 adult male Sprague–Dawley (SD) rats (weighing 200–250 g) were randomly divided into six ...

Comparative Topographic and Tomographic Assessment of Post‐LASIK Corneal Ectasia

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To evaluate and compare the topographic and tomographic characteristics of post–laser in situ keratomileusis (LASIK) ectasia (PLE) with keratoconus (KC) and normal control eyes using the Sirius imaging system. Methods This comparative cross‐sectional study included eyes with KC, PLE ectasia, and normal control eyes.

Evaluation of interface quality in organ-cultured lamellar corneal transplants [PDF]

, 2012
Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical

Corneal densitometry changes in keratoconus patients after intrastromal corneal ring segments implantation

Journal of the Egyptian Ophthalmological Society
Background Keratoconus (KC) is an ectatic corneal disorder characterized by progressive corneal thinning with myopic astigmatism. Intrastromal corneal ring segments (ICRS) have been broadly selected as a surgical intervention for KC correction to delay ...
