Representative cases of preoperative intraretinal fluid (IRF) (a, b), new IRF (cg) and IRF(−) groups (h, i). a IRF (yellow dotted line) was observed in the baseline OCT image. b At 3 months postoperatively, IRF disappeared and disrupted ellipsoid zone (yellow arrowheads) was observed. ce Serial changes in optical coherence tomography (OCT) findings in a patient without preoperative IRF. c No IRF was observed in the baseline OCT images. d Intraretinal fluid first appeared 1 month postoperatively and persisted up to (e) 1 year. Visual acuity improved from 20/200 at baseline to 20/125 at 1 year. f Fluorescein angiography, performed before surgery, demonstrated mild perifoveal microvascular leakage without disc leakage. g Prominent parafoveal microvascular leakage was noted in fluorescein angiography at 1 year postoperatively. h There was no IRF before surgery in patients of the IRF (−) group. i Until 6 months postoperatively, the OCT image showed no IRF
