Summary
Pars-plana vitrectomy with epiretinal membrane peeling (PPV-MP) significantly improves best-corrected visual acuity (BCVA) over 10 years. Outer retinal layer integrity on OCT correlates with visual gains after PPV-MP.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Visual Acuity Research
Background:
- Epiretinal membranes (ERMs) can impair vision.
- Pars-plana vitrectomy with epiretinal membrane peeling (PPV-MP) is a surgical option for ERM.
Purpose of the Study:
- To evaluate long-term visual acuity and anatomical outcomes after PPV-MP.
- To assess the correlation between retinal structure and visual function post-surgery.
Main Methods:
- Retrospective case series of patients undergoing PPV-MP.
- LogMAR best-corrected visual acuity (BCVA) tracked preoperatively and up to 10 years postoperatively.
- Spectral domain optical coherence tomography (SD-OCT) used to assess outer retinal layer integrity.
Main Results:
- Mean BCVA improved significantly from 0.56 preoperatively to 0.28 at 10 years (p<0.001).
- Visual acuity improved for the first 3 years and remained stable thereafter.
- Enhanced integrity of the external limiting membrane (ELM) and external limiting membrane (EZ) correlated with improved BCVA.
Conclusions:
- PPV-MP leads to sustained visual acuity improvement over 10 years.
- Outer retinal layer integrity is a key factor in visual recovery after ERM surgery.
