Study of Impact of Air vs SF6 20% on Visual Acuity Improvement After Epiretinal Membrane Stripping

The purpose of this study is to determine if one of these gaz (air and sulfur hexafluoride) is better than the other in epiretinal membrane peeling surgery. Both are already used for this surgery and this study will tell us if one is better than the other.

Inclusion criteria

Clinical diagnosis of epiretinal membrane with corresponding optical coherence tomography
ETDRS visual acuity worse or equal to 20/30
Adult able to give consent

Exclusion criteria

Diagnosis of age-related macular degeneration

Treatment and study plan

Epiretinal membrane peeling with fluid-air exchange

Procedure

The intervention starts with a pars plana vitrectomy and then a epiretinal membrane peeling is performed. During the fluid-gaz exchange, the gaz used will be air. The remaining of the intervention is the same between the two arms.

Epiretinal membrane peeling with fluid-SF6 exchange

Procedure

The intervention starts with a pars plana vitrectomy and then a epiretinal membrane peeling is performed. During the fluid-gaz exchange, the gaz used will be SF6 (sulfur hexafluoride). The remaining of the intervention is the same between the two arms.
