Membrane épirétinienne
A membrane on the vitreal surface of the retina resulting from the proliferation of one or more of three retinal elements: (1) fibrous astrocytes; (2) fibrocytes; and (3) retinal pigment epithelial cells. Localized epiretinal membranes may occur at the posterior pole of the eye without clinical signs or may cause marked loss of vision as a result of covering, distorting, or detaching the fovea centralis. Epiretinal membranes may cause vascular leakage and secondary retinal edema. In younger individuals some membranes appear to be developmental in origin and occur in otherwise normal eyes. The majority occur in association with retinal holes, ocular concussions, retinal inflammation, or after ocular surgery. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p291)

[Thésaurus HELB]:Paramédical:Coronavirus 2 du syndrome respiratoire aiguRésumé : SIGNIFICANCE: This analysis and review demonstrate that, although emerging data indicate that the prevalence of severe acute respiratory coronavirus 2 (SARS-CoV-2) on the ocular surface and coronavirus disease 2019 (COVID-19) conjunctivitis is rare, the ocular surface remains of interest as a potential inoculation and transmission site for SARS-CoV-2. Continued safety precautions should be taken as more data become available. COVID-19, caused by SARS-CoV-2, is a novel, global pandemic that has infected millions and, up to this point, caused more than two million fatalities worldwide. The ocular surface has become of interest as a possible vector for transmission by acting as a direct inoculation site, being a conduit for the virus into the respiratory system or as a method of transmission from potentially infected conjunctiva or tears. The components necessary for SARS-CoV-2 to theoretically infect ocular tissues are present: binding receptors (angiotensin-converting enzyme 2 and cluster of differentiation 147) and mechanisms for cell entry (transmembrane protease serine 2 and cathepsin L). This meta-analysis of COVID-19 prevalence data indicates that SARS-CoV-2 RNA has been infrequently found in conjunctival samples when tested with reverse transcriptase–polymerase chain reaction. This review estimates the prevalence of SARS-CoV-2 on the ocular surface and prevalence of conjunctivitis in patients with laboratory-confirmed COVID-19. There is much to be learned regarding ocular tropism of SARS-CoV-2. Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Tomographie par cohérence optiqueRésumé : SIGNIFICANCE
Epiretinal membrane is a common macular pathology known to cause morphologic changes observed on macular optical coherence tomography (OCT) and retinal nerve fiber layer (RNFL) OCT. However, the longitudinal effect of epiretinal membrane progression on RNFL OCT morphology is not well studied.
PURPOSE
This report documents a case of epiretinal membrane progression with associated quantifiable changes to the RNFL OCT over time.
CASE REPORT
A 63-year-old man initially presented in 2014 with a grade 0 epiretinal membrane in his left eye and low suspicion of glaucoma in both eyes. Over the next 6 years, his left eye's epiretinal membrane gradually worsened. Along with this change, the RNFL OCT started to show areas of adjacent suspected RNFL thickening and thinning compared with baseline per guided progression analysis (GPA). Despite this, clinical suspicion for actual glaucomatous progression was low. Closer retrospective analysis suggested that the RNFL was continuously dragged temporally toward the macula over this period. Because of traction, values such as the angular location, width, and peak thickness of the inferior RNFL bundles changed. This dynamic shift of a typically stationary structure contributed to an inability to rely on the RNFL OCT GPA to correctly stratify concern for glaucomatous progression.
CONCLUSIONS
Both macular and RNFL OCT allow us to observe morphologic changes to the retina caused by epiretinal membrane. Other authors have described this phenomenon, but this case demonstrates the continual change over time, suggestive of a dynamic process that requires continuous awareness and monitoring. Clinicians should be especially aware of this phenomenon when a patient is also suspicious of glaucoma. These RNFL changes can make it more problematic to rely on the OCT GPA to determine early progressive glaucomatous changes to the RNFL.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
