Peripapillary Retinoschisis: The Expanded Spectrum and New Insights From Multimodal Imaging

The 9 aetiologies of peripapillary retinoschisis can be classified into 5 groups: non-glaucomatous optic disc abnormalities (CDA, PP-coloboma, PP-atrophy), glaucomatous optic disc abnormalities, peripapillary choroidal diseases (PPS and PP-CNV), vitreous optic disc interface abnormalities and idiopathic. A new entity, "Focal Optic Disc Dome" (FODD) was identified. Understanding the full spectrum of PPRS can assist in correct diagnosis and management.
