Vitreous Detachment and Glaucoma Progression

Rate of Visual Field Progression Before and After Posterior Vitreous Detachment

Posterior vitreous detachment is a common event. With optical coherence tomography, the investigators can precisely follow the stage of posterior vitrous detachment. In this study, the investigators investigate if the loss of contact between the vitreous and the fovea is the start of glaucoma progression.

Inclusion criteria:

• Patient with glaucoma
• at least 4 years of follow up
• at least 6 visual fields
• at least 4 optical coherence tomographies

Exclusion criteria:

• pars plana vitrectomy
• others ophtalmological or neurological disease which can modify visual fields
