Anterior PVR is the most common cause of failure to reattach the retina after vitrectomy for PVR. Anterior PVR does usually not occur in primary detachment. It occurs typically in recurrent detachments after vitrectomy. Anterior PVR is PVR occurring at the height of the peripheral retina and the vitreous base. Three major tractional forces are present in anterior PVR. The first one is an anteroposterior tractional force, the second is a circumferential tractional force, and the third minor force is a perpendicular tractional force.
