The clinical study of primary pars plana vitrectomy for simple forms rhegmatogenous retinal detachment

Objective To evaluate the clinical results of primary pars plana vitrectomy as the first treatment methods for simple forms rhegmatogenous retinal detachment. Methods In this prospective consecutive clinical trial, 26 eyes of 26 patients with superior retinal break and proliferative vitreoretinopathy(PVR) stage C1 or less were enrolled. Patients underwent pars plana vitrectomy with cryotherapy and C3F8 tamponade. All patients were followed from 2 to 16 months with an average follow-up of 9 months. Reattachment of the retina and best corrected visual acuity(BCVA) and complications were recorded. Results Reattachment was achieved in all eyes(100%) with a single operation. Final BCVA was improved. VA was 0.2 to 0.3 in 9 eyes(34.6%) and 0.3 to 1.0 in 17 eyes(65.4%). Insufficient cryotherapy were found postoperatively in 8 eyes(30.8%). These retinal breaks were treated with photocoagulation. One patient(3.8%) had posterior subcapsular opacity at the 1-month postoperative visit. 12 eyes(46.2%) were present with higher intraocular pressure and recovered after 1 week. Conclusion The primary vitrectomy as the first option for simple rhegmatogenous retinal detachment with superior break can be applied to the patient with enough economic support.
