[Proliferative vitreoretinopathy as a cause of early recurrence of retinal detachment]

Analysed were the results of surgical treatment, causes of the failure and early recurrence in 108 patients with retinal detachment in whom was performed an indentation of the sclera by means of a balloon (1st group--50) or by an episcleral implant (2d group--58). In the first group the apposition was achieved in 92 p.c., in the 2d group in 90 p.c. An early recurrence (2 weeks to 2 months) was observed in 9 eyes which were operated again achieving an apposition of the retina in 6 eyes. There were following causes of the failure: the existence of a second hole, rupture of the balloon, PVR before surgery and traction of the retina in the region of the hole. An early recurrence occurred in the consequence of intensification of the PVR together with inaccurate localization of the implant, existence of the PVR before the operation and traction of the retina in the vicinity of the hole, formation of a new hole.
