Study of OCT Peripapillary Angiography in Patients With Advanced Glaucoma

Inclusion Criteria: * Men and women aged 18 and over * Patient with glaucoma followed in the ophthalmology department of Nantes University Hospital * mean visual field deficit (MD) \>10dB Exclusion Criteria: * Retinal vascular pathology (moderate to severe non-proliferative diabetic retinopathy, complicated diabetic retinopathy, OVCR/OBVR, OACR/OBAR, NOIAA...) Non-glaucomatous optic neuropathy, neurological pathology leading to visual field deficit (stroke with HLH, quadranopsia, chiasmatic Sd...) * PPR (retinal PanPhotocoagulation), retinal cerclage * Retinal pathology leading to visual field impairment (e.g. retinitis pigmentosa) * AMD and other macular pathologies that can lead to central visual field deficits * Significant environmental disorders impairing retinal imaging (e.g. active uveitis, dense cataract) * Loss of fixation point preventing visual field formation Pregnant or breast-feeding women * Protected adults under guardianship or curatorship * with unreliable visual fields (false positives and false negatives \> 33%) * with an uninterpretable OCTrnfl or OCTa (artifact, low quality score)
