Multifocal Electroretinography Before and After Silicone Oil Removal

Multifocal Electroretinography Before and After Silicone Oil Removal

This is a prospective observational study to investigate the changes in multifocal electroretinogram signal before and after silicone oil removal in silicone-filled eyes.

Inclusion Criteria:

• Patients 18 years of age or older who underwent pars plana vitrectomy for the repair of rhegmatogenous retinal detachment (RRD) and received silicone oil as an intraocular tamponade.

Exclusion Criteria:

• Patients will be excluded if they have a significant corneal opacity, uncontrolled intraocular pressure, a confounding macular pathology or optic nerve pathology or if silicone oil has been in the eye for longer than 6 months.
