研究目的
To report the anatomic and functional outcomes of retinectomy for the management of rhegmatogenous retinal detachment complicated by proliferative vitreoretinopathy (PVR), comparing them with previously reported data and determining prognostic factors.
研究成果
Retinectomy is a surgical option providing good anatomical and reasonable visual outcomes in complicated retinal detachment with PVR. Better preoperative visual acuity, lesser extension of PVR, and the use of gas tamponade during the primary repair are relevant factors for a successful outcome whereas re-proliferation of epiretinal membranes seems to be the main reason of anatomical failure.
研究不足
The retrospective collection of the data is the most important limitation. In addition, no direct comparison with a control group including eyes undergoing combined vitrectomy and scleral buckle surgery for the treatment of advanced PVR was performed.
1:Experimental Design and Method Selection:
A retrospective study of 51 eyes of 51 patients with established PVR grade C who underwent retinectomy. The study evaluated anatomic success rate, final visual acuity, intraoperative complications, number of re-operations, and postoperative hypotony.
2:Sample Selection and Data Sources:
Fifty-one consecutive patients undergoing surgery for RRD at a university teaching center and a private clinical center specialized in retinal disorders were included.
3:List of Experimental Equipment and Materials:
Standard 20G and 23G three-port pars plana vitrectomy system, membrane blue (DORC, Zuidland, the Netherlands), perfluoro-n-octane (PFCL), silicone oil (SO) 5,700 or 1,300 cS.
4:Experimental Procedures and Operational Workflow:
All operations were performed using a standard 20G and 23G three-port pars plana vitrectomy system. Meticulous removal of all preretinal membranes was performed with forceps after staining them with membrane blue. Retinectomy was performed using vertical scissors or a vitreous cutter.
5:Data Analysis Methods:
Statistical analysis was performed with SPSS software for Windows (version 16.0, SPSS, Inc, Chicago, IL, USA).
