Influence of Postoperative Posture on Macular Slippage after Macula-Off Retinal Detachment: A Randomized Controlled Trial

Abstract

Abstract Introduction To evaluate the effect of postoperative posture on the retinal shift after retinal detachment repair. Methods Patients 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. Results The 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). Conclusion In 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.
