Implantation und Explantation von inaktiven, epiretinal fixierten Retina Implant Systemen am Minipig
… where stimulation of the retina is performed via epiretinal, subretinal or transscleral electrodes. Preliminary studies suggest that electric stimulation at the level of the retina via a chronically implanted micro-contact-foil is able to induce stable visual phenomenons in patients over an …

Investigating the role of artificial intelligence in the screening, classification, diagnosis and management of epiretinal membrane
Η επιαμφιβληστροειδική μεμβράνη (ERM) αποτελεί μια συχνή παθολογία του αμφιβληστροειδούς που σχετίζεται με προοδευτική μείωση της όρασης, απαιτώντας έγκαιρη και ακριβή εκτίμηση. Οι πρόσφατες εξελίξεις στην τεχνητή νοημοσύνη (AI) έχουν καταστήσει δυνατές αυτοματοποιημένες μεθόδους για την ανίχνευση, …

Genetic, Cellular and Ultrastructural Mechanisms in Retinal Detachment
… detachment or vitreomaculopathies, including epiretinal membrane and macular hole. Using RNA-Seq, the transcriptome was analysed in surgical samples from patients having 1) vitrectomy for uncomplicated PVD, 2)_RRD, 3) epiretinal membrane, 4) macular hole and 5) vitreomacular traction. Limited …

The Transformation of Human Retinal Pigment Epithelial Cells
… and participate in the formation of contractile epiretinal membrane.</p> <p>In vitro, human RPE cells in the presence of vitreous undergo a similar transformation as they do in PVR in vivo. In 25% vitreous, RPE cells become fibrotic, migratory and invasive. Besides, EMT-related genes (Snail, …

Corneal complications related to retinal surgical patients including analysis on silicone oil use
… corneal complications. Retinal detachment and epiretinal membrane were largest quantities of a specific retinal problem with low percentages of fewer than 15% with complications postoperatively. The study found that in our patient demographic silicone oil did not seem to be a factor in causing …

Physikochemische und biologische Charakterisierung von texturiertem Silikon als Grundlage für die Entwicklung eines Retina-Patchs
… is intended that the Retina-Patch will be placed epiretinally at the retinal break and be fixed by proliferation of Müller cells (glial cells) located in the retina in the pores of the Retina-Patch. In this study, it was investigated whether textured silicone (TS) complies with the basic …

Analyse verschiedener Netzhautkulturmodelle an der Netzhaut vom adulten Hausschwein
… in histological characteristics similar to epiretinal and intraretinal gliosis observed in vivo. Therefore this culture system can be used as in vitro model for retinal gliosis. Immunohistochemistry of Co-Cultures with Muller cells showed an increase in all glial specific proteins such as …

Profili di espressione dei miRNA nelle patologie vitreoretiniche.
I microRNA (miRNA) sono piccoli RNA non codificanti, in grado di regolare l'espressione genica a livello post-trascrizione e traslazionale. Diversi studi hanno dimostrato che i miRNA regolano vari processi cellulari, tra cui la differenziazione, lo sviluppo, l’invecchiamento, l’apoptosi, …

Caracterización de membranas epiretinianas en oclusiones venosas de la retina mediante angiotomografía de coherencia óptica
Objetivo: Evaluar las características clínicas y angiotomográficas (OCT-A) de los pacientes con membranas epiretinianas (MER) secundarias a oclusiones venosas de la retina (OVR). Métodos: Estudio observacional de corte transversal. Se revisaron retrospectivamente imágenes de OCT-A e historias …
