a OCT of the peripapillary area (top) shows retinoschisis at the level of the outer nuclear layer and, to a smaller degree, the inner nuclear layer. The retinoschisis does not extend to involve the fovea (bottom). b OCT angiography of the optic disc confirms the absence of peripapillary neovascularization in the retina or the choroid. Structural OCT B-scan shows peripapillary schisis involving both the temporal and nasal retina around the optic disc.

Optical coherence tomography (OCT) of the peripapillary and the macular area of the right eye (Fig. 1a) revealed schisis of the peripapillary retina, more prominent at the level of the outer nuclear layer and less so at the inner nuclear layer. It was also noted that the PPRS involved the retinal area nasally to the optic disc, with the presence of schitic fluid in the outer retinal layers. (Fig. 1b).
One month after presentation, OCT (left) shows complete resolution of PPRS and EDI-OCT (right) confirms the absence of any structural defect in the lamina cribrosa. EDI-OCT, enhanced depth imaging OCT.

Four weeks later, OCT showed complete resolution of the PPRS in the right eye (Fig. 2) and IOP measured 16 mm Hg.
