Epiretinal membrane formation in Terson syndrome.
Clinical features of epiretinal membranes were examined in 22 eyes of 13 patients with Terson syndrome who were treated with pars plana vitrectomy. The shape and localization of the epiretinal membranes were intraoperatively evaluated and correlated with the presence or absence of posterior vitreous detachment (PVD). Patients with complete PVD, but with no membrane found during surgery, were fo...
متن کاملInflammatory Mechanisms of Idiopathic Epiretinal Membrane Formation
The pathogenesis of idiopathic epiretinal membranes (iERMs), a common pathology found in retina clinics, still eludes researchers to date. Ultrastructural studies of iERMs in the past have failed to identify the cells of origin due to the striking morphologic changes of cells involved via transdifferentiation. Thus, immunohistochemical techniques that stain for the cytostructural components of ...
متن کاملVitreoretinal juncture; epiretinal membranes and vitreous.
This report reviews current knowledge of the ultrastructural features of the vitreoretinal juncture in its normal state, in eyes with posterior vitreous detachment (PVD), and in eyes with epiretinal membranes (ERM's) and then presents new concepts concerning the interrelationship of ERM's and the vitreous. Results show no vitreous residues on retinal surface following uncomplicated rhegmatogeno...
متن کاملAssessment of retinal pigment epithelial cells in epiretinal membrane formation.
BACKGROUND The definite etiology of epiretinal membrane (ERM) is unknown. Clinically, ERM may cause metamorphopsia and decreased vision during the disease exacerbation. Several theories of pathogenesis emphasize a glial tissue origin. However, in some studies, surgically removed ERM specimens were found to contain retinal pigment epithelial (RPE) cells. The actual mechanism by which RPE cells g...
متن کاملEpiretinal membrane formation associated with idiopathic macular telangiectasia: case report.
A 46-year-old woman complained of blurred and distorted vision in both eyes. Ophthalmic examination showed that visual acuity was 20/200 for the right eye and counting fingers left eye. Fundoscopy revealed perimacular hemorrhages, aneurismal dilatation of the vessels in the posterior pole, and a white and elevated lesion adjacent to vascular changes. We report a case of idiopathic macular telan...
