Idiopathic ERM and Metamorphopsia: A New Tool for Pre- and Post-operative Evaluation

SCIENTIFIC POSTER 2016_Idiopathic ERM and Metamorphopsia A New Tool for Pre- and Post-operative Evaluation Elisa Buschini Idiopathic epiretinal membrane (IERM) is defined as an avascular proliferation of different types of cells between the posterior vitreous cortex (PVC) and the internal limiting membrane (ILM). A premacular membrane can remain asymptomatic for much time or it can cause blurred vision. Furthermore, IERM can contract...

ERM with Unusual Foveolar Adhesion

Purpose: Epiretinal membranes (ERM) are collections of collagenous cells that occur on the inner surface of the central retina and can lead to visual changes because of their effect on the underlying retina. This ocular pathology was first described by Iwanoff in 1865, and it has been shown to be a relatively common entity, occurring in about 7% of the population. ERM occur more frequently in the older population and both sexes appear to...

The Importance of Gas Injection in Idiopathic ERM Peeling Recovery

Advantages: Inner limiting membrane (ILM) removal has become a standard procedure in idiopathic epiretinal membrane (iERM) peeling over the last 15 years but some entities still respond poorly to surgery, like pseudo-lamellar holes, either in their final visual acuity or metamorphopsia reports. Herein, we propose to investigate the importance of gas injection as a tamponade in every instance of iERM peeling and examine the effect on...

What is an ERM; How Could ILM Peeling Work?

An idiopathic epiretinal membrane is a syndrome associating a macular oedema, a reactive astrocytic gliosis and an adherent plaque of posterior hyaloid. The astrocytic proliferation enters the hyaloid fibres so that the typical reflection can appear. When there is no adherent plaque of hyaloid, an aspect of pure oedema is observed. ILM removal has two functions: It removes the hyaloid fibres entirely and therefore treats the retraction...
