We believe that the use of intravitreal corticosteroids post-operatively has the capacity to mitigate much of the residual swelling and retinal thickening that is seen after vitrectomy for epiretinal membranes. The unique pharmacokinetics of the sustained released dexamethasone implant (Ozurdex®) makes it an ideal delivery system to use post-vitrectomy for epiretinal membrane surgery. Its duration of action and its drug delivery characteristics over 6 months approximately match the post-operative time course of healing and remodeling in an edematous retina.
This is a prospective, multicentre, pilot study evaluating the efficacy of an intravitreal sustained release dexamethasone implant (Ozurdex®) injected at the conclusion of surgery in 15 patients undergoing vitrectomy and membrane peeling for idiopathic epiretinal membranes.

biodegradable 0.7mg dexamethasone implant
Other Name: 0.7mg dexamethasone implant
- Best corrected visual acuity [ Time Frame: 3 Months ]Best corrected visual acuity measured before surgery and 3 months after surgery using an early treatment diabetic retinopathy study (ETDRS) chart.
- Best corrected visual acuity at 1,4 and 6 months [ Time Frame: 6 months ]Best corrected visual acuity measured at 1,4 and 6 months after surgery using an early treatment diabetic retinopathy study (ETDRS) chart.
- Retinal thickness and volume [ Time Frame: 6 months ]Measure the change in retinal thickness and volume from baseline and at 1, 3, 4, 6 months using optical coherence tomography (OCT).
- Intraocular pressure (IOP) [ Time Frame: 6 months ]Change of IOP from baseline will be monitored.
- Cataract progression (if applicable) [ Time Frame: 6 months ]For phakic patients, cataract progression from baseline to the 6 months visit will also be monitored.
