Evaluation of Retinal Parameters in Patients With Epiretinal Membrane After Vitrectomy

Laser-treated group will receive additional subthreshold micropulse laser therapy (SMLT) 1 month after pars plana vitrectomy (PPV), using a 577 nm solid-state yellow diode laser applied to the macular area (thirty 5 × 5 spot sizes of 160 µm, zero-spot spacing, including the fovea; fixed power 250 mW; exposure time 200 ms; micropulse mode, 5% duty cycle). Control group (nonlaser group) will not receive additional laser treatment.

Both groups will undergo pars plana vitrectomy (PPV) with epiretinal membrane (ERM) and internal limiting membrane (ILM) peeling prior to allocation to study arms.
