Effects of Primary Vitrectomy for Complicated Pseudophakic Rhegmatogenous Retinal Detachment

[Objective] To investigate the results and complications of primary vitrectomy for treatment of complicated pseudophakic rhegmatogenous retinal detachment.[Methods] The study reviewed 106 cases of primary vitrectomy as the initial surgery for complicated pseudophakic rhegmatogenous retinal detachment, all cases had a minimum follow-up of 6 months. Preoperatively, 26 cases had a history of posterior capsulotomy used Nd:YAG and no retinal breaks were detected in 27 cases. [Results] The primary and final retinal reattachment were achieved in 72.6% (77/106) and 98.1% (104/106) of cases respectively. Postoperative visual acuities of 0.3 was achieved in 59.4% (63/106) and 0.1 in 15.1% (16/106), compared with preoperative visual acuity (0.3 only in 34% and 0.1 in 50%), there was a significant difference (χ2=23.31,P 0.001). The main complications of primary vitrectomy were intraoperative iatrogenic retinal breaks (6.6%), postoperative proliferative vitreoretinopathy (14.2%) and macular pucker (23.6%).[Conclusion] For complicated pseudophakic rhegmatogenous retinal detachment, a high final retinal reattachment rate and relatively good functional results could be achieved by primary vitrectomy. However, the complications such as iatrogenic retinal breaks should be avoided to occur by every means.
