Purpose: This study aimed to evaluate fixation stability and position changes after epiretinal membrane (ERM) surgery. Methods: This is a retrospective study that included 60 consecutive eyes with idiopathic ERM. All patients received comprehensive ophthalmic examinations preoperatively and 1, 4, and 10 months postoperatively. Main outcome measures included fixation stability and position, bivariate contour ellipse area, and preferred retinal locus. Results: The number of patients with stable fixation and predominantly central fixation was increased significantly after ERM surgery (61.7 vs. 73.3%, P = 0.001; 41.7 vs. 71.7%, P = 0.037). The correlation analysis showed that the preoperative factors associated with improved postoperative fixation stability were a larger bivariate contour ellipse area value (P < 0.001), poorer visual acuity (P = 0.002), advanced stage (P = 0.002), thicker central fovea thickness (P = 0.015), and a longer preferred retinal locus-fovea distance (P = 0.025). As for the improved fixation location, the associated preoperative factors were age (P = 0.003), central fovea thickness (P = 0.044), and preferred retinal locus-fovea distance (P < 0.001). Conclusion: Our observations point to the changes of fixation parameters in patients after ERM surgery. We found that patients with preoperative unstable, eccentric fixation and poor BCVA can significantly benefit from the surgery. This result indicates that even in patients with severe macular damage, the ERM surgery still has great benefits in recovering visual function.
