Vitrectomy and silicone oil injection were performed for treatment of 43 patients with complicated retinal detachment (RD, n=21 ) or subsequent atrophia bulbi (AB, n=22). Retinal reattachment was achieved in 14 (66.7%) of 21 patients with RD, including 11 with idiopathic proliferative
vitreoretinopathy (PVR),6 with traumatic PVR, 3 with congenital uveal coloboma or Marfan syndrome. The visual acuity was better than 0.05 in 7(50%) of successful cases,and better than 0.02 in 11 (78.6%).Only 6(27.3%) patients had retina reattached with visual improvement in 22 cases of AB, including 13 of traumatic PVR,8 of idiopathic PVR.However,the intraoccular pressure was stable and shrinkage of the globe was controlled in 21 (95.5%) of 22 patients with AB.The results indicate that silicone off injection following vitrectomy may provide advanced severe PVR with a chance of successful treatment.
