Differences from G1: macula-on series. (%): number and percentage of patients in Retina 1 Project and macula-on groups G1, G2, G3, and G4. G1: macula-on group, G2: phakic and pseudophakic patients, G3: phakic patients, and G4: pseudophakic patients; CI: confidence interval; PVR: proliferative vitreoretinopathy; PVD: posterior vitreous detachment. VA: visual acuity, best corrected visual acuity.
