Summary
Metamorphopsia, or distorted vision, is common after retinal detachment repair. Retinal shift is the primary cause of this visual disturbance following successful macula-off rhegmatogenous retinal detachment surgery.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Visual Perception
Background:
- Macula-off rhegmatogenous retinal detachment (RRD) requires surgical intervention.
- Successful repair of RRD can still lead to visual disturbances like metamorphopsia.
- Understanding the causes of metamorphopsia is crucial for patient management.
Purpose of the Study:
- To investigate the etiologies of metamorphopsia after successful retinal detachment repair.
- To identify the primary cause of visual distortion post-macula-off RRD surgery.
Main Methods:
- Retrospective study of patients undergoing pars plana vitrectomy (PPV) for macula-off RRD.
- Postoperative assessment included best-corrected visual acuity (BCVA), biomicroscopy, Amsler grid, SD-OCT, and FAF.
- Evaluation focused on retinal layer abnormalities and retinal rotation.
Main Results:
- 12 out of 50 eyes (24%) reported postoperative metamorphopsia.
- Retinal shift was identified as the main cause of metamorphopsia (p < 0.001).
Conclusions:
- Metamorphopsia is a common complication after successful macula-off RRD repair.
- Retinal shift is the principal factor contributing to metamorphopsia in these patients.
