Top: color photographs of the left eye at the initial examination (a), 1 month after the initial examination (b), and before surgery (c). Bottom: the corresponding vertical OCT scans. a The OCT scan demonstrates a partially rolled-up hyperreflective ERM. Diffuse retinal thickening with areas of hyporeflective cystic spaces is also seen. b The OCT scan demonstrates reduced foveal thickness and smooth retinal surface. c The color photograph shows a semi-transparent ERM. The OCT scan demonstrates macular thickening with areas of hyporeflective intraretinal cystic spaces and an undulating retinal surface.

A fundus examination of the left eye revealed a distinct ERM, but PVD was not confirmed (fig. 1a). Optical coherence tomography (OCT) demonstrated a partially rolled-up ERM, diffuse retinal thickening, and the absence of foveal pit (fig. 1a). A fundus examination showed that PVD had occurred and ERM had spontaneously resolved with minimal retinal folds remaining (fig. 1b). OCT clearly showed reduced foveal thickness and a smooth retinal surface (fig. 1b). A fundus examination revealed a semi-transparent ERM with a size of about 2 disk diameters (fig. 1c). An OCT scan demonstrated macular thickening with areas of hyporeflective intraretinal cystic spaces and an undulating retinal surface (fig. 1c).
A hematoxylin-eosin-stained section of the excised specimen. The asterisks indicate the ILMs, closed arrowheads indicate the inner surface (vitreal side), and open arrowheads indicate the irregular outer surface (retinal side) of the ILMs. The surgical specimen consists of undulating ILMs and a continuous sheet of cells overlying the inner surface of the ILMs (arrow). Scale bar = 25 microm.

A microscopic examination of the excised specimen showed the characteristic undulating internal limiting membrane (ILM) and a continuous sheet of cells overlying the inner surface of the ILM (fig. 2).
