Progressive optical coherence tomography (OCT) of a case of optic disc pit maculopathy, with spontaneous resolution after posterior vitreous detachment.. (a) En-face reconstruction of the posterior pole, showing a round-shaped defect nasally to the optic disc, corresponding to the optic disc pit. The horizontal OCT passing through the fovea (red arrow) showed a reduced foveal thickness, schisis-like changes, a broad vitreal adhesion in the optic nerve head area, a posterior hyaloid thickening, vitreal entrapment in the premacular space, and a focal subfoveal defect in the photoreceptor layer. (b) The horizontal OCT in the same position showed resolution of the vitreomacular traction and the weakening of the vitreal adhesion on the optic nerve head. (c), [d] The OCT scans at the last follow-up visit showed a completely released vitreal adhesion on the optic nerve head and a full restoration in the photoreceptor band subfoveally.

SD-OCT B-scans of the macular region revealed a reduced foveal thickness; intraretinal schisis-like changes between the outer nuclear layer and the outer plexiform layer; a broad vitreal adhesion in the optic nerve head area; a diffuse parafoveal vitreomacular traction due to a posterior hyaloid thickening, with significant neuroretinal distortion; and vitreal entrapment in the premacular space (Figure 1(a)). Subfoveal focal interruption of the inner segment-outer segment (IS-OS) band and a defect of the lamina cribrosa at the site of the ODP were also discernible on the tomographic scan. Over the next 3 months, the vision of the RE dramatically improved until a BCVA of 1.0, and the macular schisis progressively resolved and spontaneous posterior vitreous detachment from the optic nerve head was noted (Figure 1(b)). The macular anatomy, including the IS-OS band, was perfectly restored (Figure 1(c)).
