Study of OCT Peripapillary Angiography in Patients With Advanced Glaucoma
Glaucoma is a chronic disease of the optic nerve, characterized by progressive loss of nerve cells in the retina, leading to progressive loss of peripheral and central vision. There are in fact several types of glaucoma, which is the world's second leading cause of blindness after cataracts, and the leading cause of irreversible blindness.

To date, to our knowledge, there is no work analyzing the progression of angiographic OCT in patients with glaucoma.

The main aim of this study is to compare the 3-year progression rate of 3 examinations in advanced glaucoma patients: one functional (visual field) and two anatomical (OCTa and OCTrnfl).
- EligibilityCriteria: 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) - Gender: All - MinimumAge: 18 Years - StdAgeList: Adult, Older Adult - StudyPopulation: Patients followed at Nantes University Hospital for advanced glaucoma (MD>10dB in visual field) who had peripapillary angiography OCT, OCTrnfl and visual field at their follow-up consultation. - SamplingMethod: Non-Probability Sample
