Predictive Factors of Functional Prognosis in Patients with Rhegmatogenous Retinal Detachment Treated by Pars Plana Vitrectomy—A Retrospective Study

Background/Objectives: Rhegmatogenous retinal detachment (RRD) is a surgical emergency that causes vision loss if not properly treated. Pars plana vitrectomy (PPV) is the preferred procedure for most complex RRD cases, with a high success rate. This study aimed to evaluate the significance of predictive factors and their impact on postoperative best corrected visual acuity (BCVA) in patients undergoing PPV for RRD. Methods: In this retrospective study, 136 eyes from 135 patients who underwent PPV for RRD were examined. A robust fitting algorithm for linear models was used to assess the influence of preoperative patient-related factors on the functional outcomes of PPV for RRD. Results: Various factors were analyzed, ranging from demographic parameters, such as gender and residency, to more complex ocular findings, including BCVA, duration of symptoms, description of the RRD, retinal tears, macular status, presence of proliferative vitreoretinopathy (PVR), epiretinal membrane, or macular hole. Conclusions: Duration of symptoms, phacoemulsification during follow-up, and preoperative BCVA showed a statistically significant correlation with postoperative BCVA. Lens status, macular status, extent of retinal detachment, number of tears, and PVR did not influence the postoperative outcome.
