The vitreous fills the posterior chamber of the eye and is firmly attached, at the posterior pole, to the macula and the optic nerve head (ONH). With formation of a stepwise posterior vitreous detachment (PVD) exerted tractional forces could influence retinal functioning. Especially in patients with glaucoma the influence of vitreous traction to the ONH could mask progression, interfere with current imaging techniques and even be a cause of ONH hemorrhages. Therefore the aim of this study is to investigate whether vitreopapillary traction has a significant effect on diagnosis and follow up of glaucoma patients.
