Purpose: To evaluate spectral-domain optical coherence tomography (OCT) findings based on preferential hyperacuity perimeter (PHP) in patients after idiopathic epiretinal membrane surgery. Methods: Forty eyes of 40 patients undergoing surgery for idiopathic epiretinal membrane were included in the study. The best-corrected visual acuity, PHP, Amsler grid test, and OCT were assessed 3 months after surgery. Results: Patients were classified based on the defect of hyperacuity by PHP, as follows:

The average macular thickness and inner nuclear layer thickness in the hyperacuity defect group was thicker than the hyperacuity intact group (P = 0.041 and P = 0.045, respectively). A disrupted photoreceptor layer was more common in the hyperacuity defect group compared with the hyperacuity intact group (P = 0.001). Conclusion: With regard to metamorphopsia, a hyperacuity defect after epiretinal membrane surgery was associated with inner nuclear layer edema and photoreceptor disarrangement.
