Introduction:
This report describes a case of spontaneous epiretinal membrane (ERM) separation following an acute symptomatic posterior vitreous detachment (PVD) that was captured on imaging.
Case Presentation:
A 55-year-old female with a history of an ERM and chronic metamorphopsias in the right eye presented with 2 days of new flashes and floaters. Dilated fundus examination revealed an ERM unchanged from prior and a new Weiss ring. Optical coherence tomography (OCT) demonstrated a new detachment of the posterior hyaloid from the retina with a focal break in the ERM and an area of attachment between the posterior hyaloid and ERM. Six weeks later, OCT revealed complete ERM separation from the retina with restoration of foveal contour.
Conclusion:
This case contributes to the existing literature on spontaneous ERM separation via PVD with the mechanism of separation uniquely demonstrated on OCT. Observation may be a reasonable approach for patients with mildly symptomatic ERM who have an attached posterior hyaloid on initial imaging.
