A Pilot Study of the Effectiveness of Intra-operative Ozurdex® in Vitrectomy Surgery for Epiretinal Membranes

ClinConnect Summary

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.
