Purpose:
To investigate the etiologies of metamorphopsia after successful retinal detachment repair.
Methods:
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.
Results:
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).
Conclusion:
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.
