Primary Outcome Measures:
  • Changes in best corrected visual acuity [ Time Frame: 6 months ] [ Designated as safety issue: No ]

    At all study visits:

    ETDRS visual acuity will be measured visit excluding post op day 1 (snellen visual acuity will be measured).

    Intraocular pressure (IOP) will be checked. Spectral Domain Optical Coherence Tomography (OCT). Dilated fundus exam.

    At Pre Op, Post Op Week 4, 8, 12, 16, 20 and 24 visits:

    ETDRS visual acuity will be measured. IOP check. Spectral Domain OCT. Fundus photography. Fundus Autofluorescence (AF). Fluorescein Angiography (FA). Dilated Fundus exam.



Secondary Outcome Measures:
  • Incidence of persistent macular edema on Central OCT thickness in treatment (PPV + MP + DEX) versus non-treatment (PPV + MP) groups [ Time Frame: 6 months ] [ Designated as safety issue: No ]

    At all visits: ETDRS visual acuity will be measured except post op day 1 (snellen visual acuity will be measured) Intraocular pressure (IOP) will be checked Spectral Domain Optical Coherence Tomography (OCT) Dilated fundus exam

    At Pre Op, Post Op Week 4, 8, 12, 16, 20, and 24:

    ETDRS visual acuity will be measured IOP will be checked Spectral Domain OCT Fundus Photography Fundus Auto Fluorescence (AF) Fluorescein Angiography (FA) Dilated Fundus exam

Arms Assigned Interventions
Experimental: PPV + MP + DEX
Patients will undergo pars plana vitrectomy, membrane peel, and concomitant Ozurdex implant (0.7 mg dose).
Drug: Dexamethasone Intravtireal Implant
Half of the study participants (15 out of 30) will receive one - Dexamethasone Intravitreal Implant 0.7 mg.
Other Names:
  • Pars Plana Vitrectomy
  • Membrane Peel
  • Dexamethasone Intravitreal Implant (Ozurdex)
Active Comparator: PPV + MP
Patients will undergo pars plana vitrectomy with membrane peel, without Ozurdex implant.
Drug: Dexamethasone Intravtireal Implant
Half of the study participants (15 out of 30) will receive one - Dexamethasone Intravitreal Implant 0.7 mg.
Other Names:
  • Pars Plana Vitrectomy
  • Membrane Peel
  • Dexamethasone Intravitreal Implant (Ozurdex)

Detailed Description:

Pars plana vitrectomy with membrane peeling has been used for years to successfully to treat ERM (epiretinal membrane). However, despite successful surgery, approximately 10-30% of patients may not experience any improvement in visual acuity (ref. 1-7). Macular causes of unsatisfactory visual outcome following vitrectomy include persistent macular edema and reoccurrence of epiretinal membrane (ref. 1-7). Concomitant administration of intravitreal corticosteroids (triamcinolone acetonide) after pars plana vitrectomy and membrane peeling for epiretinal membrane has been reported to speed up and improve the anatomic and functional outcome (ref 8). Given that intravitreal triamcinolone has been reported to last approximately 113 days ina post-vitrectomy eye (ref. 9); the investigators postulate that a longer-acting corticosteroid such as Ozurdex could not only have the benefits of improved anatomic and functional outcomes, but also a longer sustained effect.
