Spontaneous epiretinal membrane resolution: mechanisms, outcomes, and implications for clinical management

To review the phenomenon of spontaneous epiretinal membrane (ERM) resolution focusing on the clinical settings, mechanisms of resolution, and implications for management.

A comprehensive review of case reports and studies describing spontaneous ERM resolution was conducted. Data were extracted regarding ERM type, patient demographics, visual outcomes, and suspected mechanisms. Findings were analyzed to identify trends and to compare cases of spontaneous resolution across different ERM types.

Spontaneous ERM resolution was more frequently observed in younger patients or cases associated with posterior vitreous detachment (PVD). In idiopathic ERMs, spontaneous separation often involved PVD and extracellular matrix remodeling. Inflammatory ERMs demonstrated resolution due to reduced inflammation and traction, while secondary ERMs linked to vascular or traumatic events benefited from mechanisms such as photocoagulation-induced PVD or gliotic contraction. Visual outcomes varied, with improvements in best-corrected visual acuity (BCVA) and metamorphopsia in most cases, though persistent structural changes occasionally limited functional recovery.

Spontaneous ERM resolution is a rare but clinically significant event influenced by vitreoretinal interface dynamics and patient-specific factors. Younger age, the presence of PVD, and underlying inflammatory or vascular conditions may contribute to natural resolution. Recognizing these cases allows for tailored management strategies supporting observation in selected patients while minimizing unnecessary surgical interventions. These insights may guide future research into therapeutic approaches that mimic natural resolution mechanisms.
