Interface Fluid Syndrome (IFS) following Toxic Anterior Segment Syndrome (TASS): not related to high intraocular pressure but to endothelial failure.

Saudi J Ophthalmol 2019 Jan-Mar;33(1):88-93. Epub 2018 Jul 7.

Centro Oftalmológico Virgilio Galvis, Floridablanca, Colombia.

We describe the case of a 52-year-old female with past history of LASIK, 21 years earlier, without Fuchs' endothelial dystrophy, who underwent phacoemulsification and intraocular lens (IOL) implantation. During the early postoperative period severe corneal edema, anterior chamber cellularity and iris inflammation presented, accompanied by a clear space along the LASIK interface. Those findings were interpreted as part of a Toxic Anterior Segment Syndrome (TASS) and secondary interface fluid syndrome (IFS). Read More

Duplex RNAs and ss-siRNAs Block RNA Foci Associated with Fuchs' Endothelial Corneal Dystrophy.

Nucleic Acid Ther 2019 Apr 24;29(2):73-81. Epub 2019 Jan 24.

1 Department of Pharmacology and Biochemistry, UT Southwestern Medical Center at Dallas, Dallas, Texas.

Fuchs' endothelial corneal dystrophy (FECD) leads to vision loss and is one of the most common inherited eye diseases. Corneal transplants are the only curative treatment available, and there is a major unmet need for treatments that are less invasive and independent of donor tissue. Most cases of FECD are associated with an expanded CUG repeat within the intronic region of TCF4 and the mutant RNA has been implicated as the cause of the disease. Read More

Born in Vienna, in mid 19th century, Ernst Fuchs became an innovative ophthalmologist and is currently considered as the father of modern ophthalmology. Conditions like heterochromic uveitis and endothelial dystrophy were discovered by Fuchs and a series of ocular diseases are named after him. His work dealing with eye pathology, entitled: "Textbook of Ophthalmology", became known as the masterpiece of the 19th century ophthalmology. Read More

A transparent cornea is essential for the formation of a clear image on the retina. The human cornea is arranged into well-organized layers, and each layer plays a significant role in maintaining the transparency and viability of the tissue. The endothelium has both barrier and pump functions, which are important for the maintenance of corneal clarity. Read More

R125H, W240S, C386R, and V507I SLC4A11 mutations associated with corneal endothelial dystrophy affect the transporter function but not trafficking in PS120 cells.

Exp Eye Res 2019 03 14;180:86-91. Epub 2018 Dec 14.

School of Optometry, Indiana University Bloomington, Bloomington, IN, USA. Electronic address:

SLC4A11 mutations are associated with Fuchs' endothelial corneal dystrophy (FECD), congenital hereditary endothelial dystrophy (CHED) and Harboyan syndrome (endothelial dystrophy with auditory deficiency). Mice with genetically ablated Slc4a11 recapitulate CHED, exhibiting significant corneal edema and altered endothelial morphology. We recently demonstrated that SLC4A11 functions as an NH sensitive, electrogenic H transporter. Read More

[Descemet membrane endothelial keratoplasty in complex eyes].

Ophthalmologe 2019 Mar;116(3):228-235

Zentrum für Augenheilkunde, Universität zu Köln, Kerpenerstr. 62, 50924, Köln, Deutschland.

Background: Descemet membrane endothelial keratoplasty (DMEK) has become the standard surgical treatment for Fuchs' endothelial corneal dystrophy (FECD) in Germany. In addition to classical FECD, there are endothelial disorders amenable to DMEK associated with complex changes in the anterior segment of the eye, such as anterior synechia of the iris, larger iris defects, after glaucoma surgery, after vitrectomy and after trauma.

Objective: This article provides an overview of the possibilities to treat patients with complex anterior segment situations in the presence of corneal endothelial decompensation with DMEK. Read More

Biomechanical changes to Descemet's membrane precede endothelial cell loss in an early-onset murine model of Fuchs endothelial corneal dystrophy.

Exp Eye Res 2019 03 22;180:18-22. Epub 2018 Nov 22.

Department of Surgical and Radiological Sciences, School of Veterinary Medicine, University of California, Davis, CA, United States; Department of Ophthalmology & Vision Sciences, School of Medicine, University of California, Davis, CA, United States. Electronic address:

Early-onset Fuchs endothelial corneal dystrophy (FECD) has been associated with nonsynonymous mutations in collagen VIII α2 (COL8A2), a key extracellular matrix (ECM) protein in Descemet's membrane (DM). Two knock-in strains of mice have been generated to each express a mutant COL8A2 protein (Col8a2 and Col8a2) that recapitulate the clinical phenotype of early-onset FECD including endothelial cell loss, cellular polymegathism and pleomorphism, and guttae. Due to abnormalities in ECM protein composition and structure in FECD, the stiffness of DM in Col8a2 knock-in mice and wildtype (WT) controls was measured using atomic force microscopy at 5 and 10 months of age, coinciding with the onset of FECD phenotypic abnormalities.

We provide the evidence for G protein-coupled receptor 35 (GPR35) presence and distribution in the human cornea. The initial data on GPR35 gene expression were retrieved from microarray repositories and were further confirmed by western blotting and immunohistochemical analysis. Immunoblotting suggested that GPR35 exists predominantly as a dimer in corneal tissue. Read More

"Ghost DMEK" Technique: Circular Peripheral Staining of Descemet's Membrane Endothelial Keratoplasty Grafts.

Cornea 2019 Feb;38(2):252-255

Department of Ophthalmology, Rabin Medical Center, Petach Tikva, Israel.

Purpose: To describe the ghost Descemet's membrane endothelial keratoplasty (DMEK) technique that allows for real-time evaluation of DMEK graft orientation, location, and folding status within the anterior chamber, by simple observation at the surgical microscope.

Methods: This is a retrospective case series done in a university hospital. The study included 10 patients who underwent ghost DMEK surgery because of corneal endothelial insufficiency for Fuchs' endothelial dystrophy (N = 5), pseudophakic bullous keratopathy (N = 2), and failed previous posterior lamellar keratoplasty (N = 3).
