    Peripapillary Microvascularization Analysis Using Swept-Source Optical Coherence Tomography Angiography in Optic Chiasmal Compression by Inès Ben Ghezala, Déa Haddad, Julie Blanc, Cyril Meillon, Rachid Madkouri, François Borsotti, Alain M. Bron, Catherine Creuzot-Garcher

    Published 2021-01-01
    “…All patients with chiasmal compression underwent a neuro-ophthalmological examination one week before and 6 months after brain surgery, including static automated perimetry as well as measurement of the thickness of the retinal nerve fiber layer (RNFL) and the ganglion cell complex (GCC) with spectral-domain optical coherence tomography (SD-OCT). Based on this neuro-ophthalmological examination, the presence of an optic neuropathy (ON) was evaluated. …”
