IntroductionTo evaluate the effect of postoperative posture on the retinal shift after retinal detachment repair.MethodsPatients who underwent pars plana vitrectomy (PPV) for macula-off rhegmatogenous retinal detachment (RRD) were included prospectively in the current study. Patients were randomized into two groups: group A included patients who did a log roll postoperatively, and group B included patients who had to lie flat on their backs for 6 h postoperatively before moving into the end position. Patients in group A and patients in group B were reviewed after 3 weeks and after 6 weeks, respectively, and fundus autofluorescence images (FAF) were obtained to visualize the retinal rotation.ResultsThe sample included 50 eyes from 49 patients. Retinal shift occurred after RRD repair in 17 patients (34%). There was no statistically significant difference between the two groups (p = 0.94). Postoperative macular shift occurred significantly less often (p  = 0.049) in participants in whom heavy fluid was used in the procedure. Metamorphopsia was reported postoperatively by 10 of 17 patients with retinal shift (p < 0.001).ConclusionIn our study, postoperative posture did not significantly influence postoperative macular slippage after RRD repair. The use of intraoperative heavy liquid appears to be associated with a lower occurrence of retinal shift.

PurposeTo investigate the outcome after combined phaco-vitrectomy in rhegmatogenous retinal detachment (RRD) repair.Patients and methodsIn this retrospective study, we included all patients who underwent pars plana vitrectomy (PPV) for RRD between January 2013 and December 2017. The main outcome measure was the retinal re-detachment rate after combined phaco-vitrectomy.ResultsOverall, 1017 eyes with RRD were included. All eyes received PPV, while in 516 eyes additional phacoemulsification was performed. A retinal re-detachment occurred in 103 patients (10.1%). No significant difference in the rate of re-detachment was found if additional phacoemulsification was performed (p=0.641). Subgroup calculations showed a significant higher rate of re-detachment in patients with a PVR (p=0.0003) and in patients where silicone oil was used as primary tamponade (p=0.0001) as well as in macula off RRDs (p=0.034).ConclusionAdditional phacoemulsification during vitrectomy for RRD is not associated with higher rate of retinal re-detachment.
