Table 3 Mean values of retinal sensitivity in decibel (dB) measurements obtained by postoperative microperimetry (MP) divided into 9 sectors plus the mean sensitivity, with the respective values of the areas under the ROC curve

From: Correlation between retinal sensitivity assessed by microperimetry and structural abnormalities on optical coherence tomography after successful epiretinal membrane surgery
