Idiopathic epiretinal membrane (iERM) surgery alters the vitreomacular interface, reducing folds and changing hyperreflective structures. Adaptive optics imaging reveals these changes, aiding treatment outcome monitoring.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Surgical Outcomes
Background:
- Idiopathic epiretinal membrane (iERM) affects the vitreomacular interface.
- Understanding post-surgical changes is crucial for patient outcomes.
Purpose of the Study:
- To investigate changes in the vitreomacular interface after iERM surgery over one year.
- To correlate adaptive optics (AO) and optical coherence tomography (OCT) findings.
Main Methods:
- Pilot study of six patients with fovea-attached iERM undergoing pars plana vitrectomy.
- AO and spectral domain OCT imaging pre- and post-surgery (1, 3, 6, 12 months).
- Inner limiting membrane removal in four cases using Brilliant blue G.
Main Results:
- Preoperatively, AO showed macrofolds, microfolds, and hyperreflective structures, defining radial and grid iERM types.
- Post-surgery, macrofolds and microfolds decreased; hyperreflective structures persisted with altered morphology.
- Differences observed between eyes with and without inner limiting membrane removal.
Conclusions:
- AO imaging provides novel insights into vitreomacular interface changes post-iERM surgery.
- Multimodal imaging is valuable for monitoring iERM treatment efficacy.
