Abstract
Background
This study aimed to evaluate the long-term change of postoperative retinal shift after pars plana vitrectomy for macular off retinal detachment.
Methods
In this retrospective study, patients with retinal shift after pars plana vitrectomy for macula-off rhegmatogenous retinal detachment (RRD) were examined at 3 weeks and 12 months postoperatively. Fundus autofluorescence images were obtained to visualize retinal rotation. Best-corrected visual acuity was measured and metamorphopsia assessed using the Amsler grid.
Results
Nine patients with postoperative retinal shift were included in the study. Retinal shift decreased significantly in these patients, on average by 1.07° (range 0.52–1.62, p = 0.002) after 12 months. However, more patients complained of distorted vision after 12 months (odds ratio for change = 3.0, 95% CI: 0.24 to 157.49). The main reason was the new formation of an epiretinal membrane (odds ratio for change = infinity, 95% CI: 0.41 to infinity). There was no change in visual acuity observed (p = 0.16).
Conclusion
Postoperative retinal shift after RRD repair decreases over a 1-year span. While retinal shift is the main cause for metamorphopsia in the early postoperative period, formation of an ERM is the main reason for distorted vision long term.
