Efficacy of vitrectomy for the pseudophakic retinal detachment

Objective To observe efficacy of 25 G+ vitrectomy system with non contact wide angle lens in the treatment of pseudophakic retinal detachment. Methods A total of 71 eyes of 71 cases with pseudophakic retinal detachment were enrolled and underwent 25 G+ vitrectomy with non contact wide angle lens. The postoperative condition of retina, postoperative vision and complications were observed and analyzed. Results The follow-up time was 3-12 months, the retina was reattached successfully after once operation in 66 eyes (92.96%). Two eyes received second operations and a third in 1 eye to achieve retinal reattachment.The retinal detachment of severe PVR occurred was untreatable in 2 eyes. Finally there were 69 eyes (97.18%) achieved retinal reattachment. Preoperative mean visual acuity (logMAR) was (1.95±0.95) compared with (1.69±0.81) at 3 months after surgery, the difference was significant between them (t=7.535, P=0.000). At 6 months after surgery, the mean visual acuity was (1.35±0.75) compared with the preoperative one the difference was statistically significant (t=14.547, P=0.000). The postoperative complications were ocular hypertonia in 2 eyes, 1 eye with macular epiretinal membrane and 1 eye with silicone oil in anterior chamber. Conclusion 25 G+ vitrectomy system with non contact wide angle lens for the treatment of pseudophakic retinal detachment is a safe and effective therapy to achieve a high anatomic and functional success rate with few complications.
