To examine the predictive findings of preoperative spectral-domain optical coherence tomography (SD-OCT) finding to pre- and postoperative best corrected visual acuity (BCVA) in macular-off rhegmatogenous retinal detachment (RRD).
18 eyes of 18 patients with macular-off RRD were retrospectively reviewed. All eyes were performed scleral buckling (8 eyes) or vitrectomy with gas tamponade (9 eyes) or both (1 eye). As preoperative SD-OCT finding, central foveal thickness (CFT), the height of foveal detachment and pre- and postoperative BCVA were measured in all patients.
Preoperatively, outer plexiform layer cyst (9 eyes: 50 %), inner nuclear layer cyst (2 eyes: 11%), outer retinal edema (12 eyes: 67%), outer retinal undulance change (9 eyes: 50%) and defect of foveal photoreceptor inner and outer segment junction (IS/OS; 4 eyes: 22%) were seen in the detached retina. Presence of outer plexiform layer cyst, outer retinal edema and outer retinal undulance change significantly worsened preoperative BCVA, though there is no correlation with postoperative BCVA. Inner nuclear layer cyst and defect of IS/OS also had no correlation with pre- and postoperative BCVA. In one eye with wide defect of foveal IS/OS, pre- and postoperative BCVA was poor. The height of foveal detachment had mild correlation with preoperative BCVA. CFT had no correlation with pre- and postoperative BCVA.
In macular-off rhegmatogenous retinal detachment, preoperative outer retinal change of detached retina correlated with preoperative BCVA but had no correlation with postoperative BCVA. Preoperative wide defect of foveal IS/OS affected pre and postoperative BCVA.
