A missense mutation of collagen type VIII alpha 2 chain ( COL8A2 ) gene leads to early-onset Fuchs’ endothelial corneal dystrophy (FECD), which progressively impairs vision through the loss cells. We demonstrate that CRISPR/Cas9-based postnatal editing achieves structural and functional rescue in a mouse model FECD. single intraocular injection an adenovirus encoding both Cas9 guide RNA (Ad-Cas...

PURPOSE The aim of this study was to describe the aims, methods, donor and recipient cohort characteristics, and potential impact of the Cornea Preservation Time Study (CPTS). METHODS The CPTS is a randomized clinical trial conducted at 40 clinical sites (70 surgeons) designed to assess the effect of donor cornea preservation time (PT) on graft survival 3 years after Descemet stripping automa...

Oxidative stress is implicated in the pathogenesis of many diseases, including serious ocular diseases, keratoconus (KC) and Fuchs endothelial corneal dystrophy (FECD). Flap endonuclease 1 (FEN1) plays an important role in the repair of oxidative DNA damage in the base excision repair pathway. We determined the association between two single nucleotide polymorphisms (SNPs), c.-441G>A (rs174538)...

PURPOSE To evaluate the leading indications for penetrating keratoplasty (PKP) and their trends in Greece during the period 1982 to 2006. METHODS Retrospective data review of 1,929 patients (2233 eyes) who underwent PKP in the period between 1982 and 2006 at three cornea transplantation units of three hospitals in Greece (Athens General Hospital, Heraklion University Hospital of Crete, and Th...

Fuchs endothelial corneal dystrophy (FECD) is characterized by pleomorphic, attenuated, dysfunctional, and degenerated corneal endothel ium together with progressive formation of corneal guttae. The condition may show familial clustering but is usually sporadic and predominantly affects women. Family based studies have mapped late onset FECD susceptibility to 13ptel-13q12.13 and 18q21.2-q21.32....

We read with great interest the article by Mootha et al. concerning a possible correlation between Fuchs’ endothelial corneal dystrophy (FECD) and myotonic dystrophy (MD). We thank the authors because, among the studies we made trying to understand the reason of low intraocular pressure in patients with MD, they cited one study we published in 2010 where we examined the endothelial cells charac...

In Alzheimer's disease (AD), β-amyloid (Aβ) plaques are tightly enveloped by microglia processes, but the significance of this phenomenon is unknown. Here we show that microglia constitute a barrier with profound impact on plaque composition and toxicity. Using high-resolution confocal and in vivo two-photon imaging in AD mouse models, we demonstrate that this barrier prevents outward plaque ex...

Corneal diseases are one of the major causes of blindness worldwide. Conservative medical agents, which may prevent sight-threatening corneal disease progression, are urgently desired. Numerous evidences have revealed the involvement of oxidative stress in various corneal diseases, such as corneal wound healing and Fuchs endothelial corneal dystrophy (FECD). Nuclear factor (erythroid-derived 2)...
