    Abstract:
    PURPOSE: To describe the findings of enhanced depth imaging (EDI) optical coherence tomography (OCT) of the lamina cribrosa (LC) in glaucoma and pachychoroid spectrum diseases associated with peripapillary retinoschisis. DESIGN: Retrospective, observational case series. PARTICIPANTS: A total of 16 patients from 1 institution. METHODS: Detailed medical case histories, optic disc and retinal imaging with EDI using the Spectralis OCT (Heidelberg Engineering, Heidelberg, Germany), and clinical course were reviewed for patients with peripapillary retinoschisis without a known predisposing condition. MAIN OUTCOME MEASURES: Clinical features and findings of the EDI OCT. RESULTS: Among the 16 eyes with peripapillary retinoschisis that had abnormal findings on EDI of the LC, 8 had glaucoma and 8 had pachychoroid spectrum diseases, including chronic central serous chorioretinopathy (CSC) (6 eyes), small pigment epithelium detachment (1 eye), and polypoidal choroidal vasculopathy (PCV) (1 eye). The abnormal LC findings were central or peripheral focal LC defects in eyes with glaucoma and LC disinsertions or peripheral focal LC defects in eyes with pachychoroid spectrum diseases. Central LC defects were related to inner layer retinoschisis, whereas LC disinsertions and peripheral LC defects were related to outer layer retinoschisis. The peripapillary retinoschisis did not show a topographic association with the underlying chronic CSC- or PCV-associated lesions. In 6 treated eyes with pachychoroid, peripapillary retinoschisis resolved along with subretinal fluid after anti-vascular endothelial growth factor injection in 4 eyes, whereas retinoschisis persisted after the resolution of subretinal fluid in 2 eyes. CONCLUSIONS: Enhanced depth imaging OCT of the LC demonstrated alterations associated with peripapillary retinoschisis, pachychoroid spectrum diseases, and glaucoma.
