Multimodal imaging for detecting metamorphopsia after successful retinal detachment repair

To investigate the etiologies of metamorphopsia after successful retinal detachment repair.
In this retrospective study, we included patients who underwent pars plana vitrectomy (PPV) for macula-off rhegmatogenous retinal detachment (RRD). Patients were reviewed after 3 to 6 weeks. Best-corrected visual acuity (BCVA), fundus biomicroscopy, Amsler grid test, spectral-domain optical coherence tomography (SD-OCT), and fundus autofluorescence images (FAF) were obtained from all patients to visualize abnormalities in retinal layers and retinal rotation.
A total of 50 eyes from 49 consecutive patients were included, of whom 12 (24%) complained of postoperative metamorphopsia. The main cause of metamorphopsia was retinal shift after RRD repair (p < 0.001).
Distorted vision after macula-off RRD is a common and retinal shift was found to be the main reason patients experience metamorphopsia after a successful macula-off RRD repair.
