Predicting Surgical Success in Patients with Idiopathic Epiretinal Membrane Using the Spectral-Domain Optical...

Area of Science:

• Ophthalmology
• Retinal Surgery
• Medical Imaging

Background:

• Idiopathic epiretinal membrane (ERM) can cause gradual vision loss.
• Surgical intervention, like vitrectomy with ERM peeling, is common.

Purpose of the Study:

• To assess retinal layers using optical coherence tomography (OCT) before and after ERM peeling.
• To correlate preoperative retinal morphology with visual acuity (VA) changes post-surgery.
• To refine surgical decision-making for ERM.

Main Methods:

• Retrospective analysis of 47 eyes from 45 patients with ERM.
• Preoperative and postoperative OCT imaging.
• Automated all-layer segmentation of nine retinal surfaces.
• Correlation analysis between retinal morphology and VA outcomes.

Main Results:

• Significant correlation found between initial retinal morphology and postoperative VA improvement.
• Patients gaining ≥2 lines of VA had higher preoperative total retinal perimacular volume and retinal nerve fiber layer thickness (p < 0.0001).

Conclusions:

• Preoperative retinal volume and nerve fiber layer thickness are predictive of surgical success in ERM patients.
• Higher tractive components in the retina suggest greater benefit from ERM peeling surgery.
