Preoperative and postoperative fundus photographs and OCT images of a 62-year-old man’s right eye. a–e preoperative images; f–j one month postoperative images; k–o three month postoperative images. a, f, k colour fundus photographs; b, g, l B-scan images; c, h, m, en face images at the internal limiting membrane (ILM) level; d, i, n en face images at 10 μm below the ILM level; e, j, o en face images at the outer nuclear layer (ONL) level. At the initial visit the macula was slightly reddish with macular hole-like conformation in the right eye (arrow, a). B-scan imaging shows the retinal cleavage (white arrows, b) and LHEP (arrowheads, b) at the macula. The ellipsoid zone was almost continuous but showed an irregular reflection intensity (black arrows, b). En face imaging revealed ERM or LHEP at the level of the ILM (arrowheads, c). There was no retinal fold at 10 μm below the ILM level (d). There was a retinal cleavage at the ONL level (arrow, e). At 1 month after surgery, the retinal cleavage was no longer present (f and g). B-scan imaging shows the presence of the embedded LHEP and the inverted ILM, although it is difficult to distinguish the two because they seem to be integrated (arrowheads, g). At 3 months after surgery, the foveal contour was further improved (k–o). B-scan imaging shows complete recovery of the ellipsoid zone (black arrows, l)
