Purpose During posterior vitreous detachment ( PVD ) the posterior hyaloid remains, for a certain period, attached to the optic disc. It can exert traction with development of optic nerve head hemorrhages ( ONHH ). ONHH are known to be associated with glaucomatous progression and retinal nerve fiber layer ( RNFL ) defects. Therefore this study aims at investigating the relationship between PVD formation and ONHH in open angle glaucoma patients. Methods Patients presenting with an ONHH , from November 2014 on, were included. They underwent a comprehensive ophthalmological investigation, automated visual field test, confocal scanner ( HRT III ), OCT ( HRT ‐Spectralis) scan and stereographic photos of the optic nerve head. This study is part of a larger, clinicaltrial.gov ( NCT 02290795) registered, study investigating vitreopapillary traction ( VPT ). Results Eighteen eyes of 18 patients (11 normal tension, 6 primary open angle and 1 secondary open angle glaucoma) were included. Seven out of 18 (38.9%) eyes had concomitant VPT and 7 had a complete PVD . Seven ONHH were located infero‐, 5 supero‐ and 6 temporal. In the non‐ VPT subgroup 5 out of 11 (45.5%) eyes showed matching retinal nerve fiber layer defects, with 2 out of 7 (28.6%) in the VPT subgroup. Conclusions VPT could be a confounding factor in glaucoma assessment and ONHH development.
