hyalocytes, RPE, glial cells
three cell types implicated in ERMs
rhegmatogenous PVD
term for when a rent in the posterior vitreous cortex causes a rapid PVD
trauma, uveitis, retinal breaks, retinal vascular occlusions, intraocular surgery
five causes of secondary ERM
20%
incidence of idiopathic ERM after age 75 based on autopsy studies
20%
percentage of ERMs that are bilateral
20/50
usual cutoff for vitrectomy and membrane peel in epiretinal membrane
PVD
thought to be necessary for ERM formation in most cases
pseudohole
term for when an ERM is discontinuous, giving the appearance of a macular hole
true
TRUE or FALSE: Return to normal vision is rare following removal of an ERM
