[Morphological characteristics of Descemet's membrane removed during endothelial keratoplasty (case study)].

Vestn Oftalmol 2022 ;138(2):81-86

Research Institute of Eye Diseases, Moscow, Russia.

The two most used modifications of endothelial keratoplasty (EK) are Descemet's membrane endothelial keratoplasty (DMEK) and Descemet's stripping automated endothelial keratoplasty (DSAEK). The leading complication of EK surgeries is graft detachment in the early postoperative period. This article reports on two cases of endothelial graft adhesion depending on morphological characteristics of the Descemet's membrane (DM) removed during EK. Read More

Beneficial Effects of Polydeoxyribonucleotide (PDRN) in an In Vitro Model of Fuchs Endothelial Corneal Dystrophy.

Pharmaceuticals (Basel) 2022 Apr 3;15(4). Epub 2022 Apr 3.

Department of Clinical and Experimental Medicine, University of Messina, Via C. Valeria, 98125 Messina, Italy.

Fuchs endothelial corneal dystrophy (FECD) is a bilateral, hereditary syndrome characterized by progressive irreversible injury in the corneal endothelium; it is the most frequent cause for corneal transplantation worldwide. Oxidative stress induces the apoptosis of corneal endothelial cells (CECs), and has a crucial function in FECD pathogenesis. The stimulation of the adenosine A receptor (A) inhibits oxidative stress, reduces inflammation and modulates apoptosis. Read More

Cataract Surgeries in Patients with Fuchs Endothelial Dystrophy.

Klin Monbl Augenheilkd 2022 Apr 14. Epub 2022 Apr 14.

Klinik für Augenheilkunde, Universitätsklinikum Freiburg, Medizinische Fakultät, Albert-Ludwigs-Universität Freiburg, Freiburg, Deutschland.

Patients with Fuchs endothelial dystrophy often develop visual symptoms between 50 - 60 years of age, which is the same time that the first symptoms of a developing cataract start to appear. On the other hand, in patients with a clinically significant cataract, corneal guttata may be detected by chance during a routine clinical workup. In both situations, the surgeon has to decide whether DMEK or cataract surgery should be performed alone or in combination. Read More

Endophthalmitis secondary to donor to host infection in posterior lamellar keratoplasties: A systematic review.

Eur J Ophthalmol 2022 Mar 11:11206721221085853. Epub 2022 Mar 11.

Department of Ophthalmology, 27968Universidad Autónoma de Bucaramanga UNAB, Bucaramanga, Colombia.

Donor to host transmission of infectious agents is a well-recognized entity, more commonly related to Endothelial Keratoplasty (EK) than to Penetrating Keratoplasty (PK), that involves complications ranging from interface keratitis to endophthalmitis. A systematic review of the literature was conducted to identify the published articles until December 2020 reporting cases of endophthalmitis secondary to corneal graft contamination in posterior lamellar keratoplasties (DSAEK and DMEK) along with donor characteristics, microbiological profile, treatment and outcomes. Each identified article was assessed to meet donor to host infection criteria, defined as a post-procedural infection in which the same microbiological agent was identified in both the donor corneoscleral rim or preservation medium and receptor ocular tissue.
