Anatomical and Functional Outcomes After Surgery for Primary Rhegmatogenous Retinal Detachments (RD) in Phakic and Pseudophakic Patients. Preliminary Results of a Multicentric Prospective Study: The Retina 1 Project

Abstract

Purpose: : To compare anatomical and functional outcomes in 546 phakic and pseudophakic primary rhegmatogenous RD treated

Methods: : Prospective, non-randomized, interventional study in sixteen centres in Spain and Portugal, with data from RD consecutively treated from January 2005 to May 2007. Cases with pre-operative proliferative vitreoretinopathy (PVR) grade C-1 or higher, and perforating trauma were excluded. Minimum follow-up was 3 months. Twenty-seven pre-, intra-, and post-surgical variables from each patient were analysed. Multivariate analysis was carried out by logistic regression analysis with stepwise selection of variables

Results: : Data from 546 patients were analysed. Global anatomic success was 94.7%. Logistic regression analysis showed only relationship of the variables with post-operative development of PVR. Poorest functional results were associated with macular involvement, extension of RD, existence of previous RD surgery, time of evolution of RD, and age of patient. By hierarchical log-linear analysis, lens status (phakic versus pseudophakic) had no affect on the functional results. However, PPV was most often performed in pseudophakic eyes and resulted in worse final visual acuity (p<0.001)by pars plana vitrectomy (PPV) or scleral buckling surgery (SB)

Conclusions: : No differences between PPV and SB were found in anatomical success in this series. PPV was most often performed in pseudophakic eyes and had a greater probability of a worse final VA than SB
