Outcome Measures

Primary Outcomes (1)

  • Changes in visual acuity from baseline to 104 weeks

    Visual acuity is assessed using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. The ETDRS chart includes 100 letters as the maximum possible score, and 0 letters read as the minimum possible score. Visual acuity of 85 letters is equivalent to 20/20. Higher scores represents better functioning.

    baseline and 104 weeks

Secondary Outcomes (7)

  • Changes in visual acuity from baseline to 52 weeks

    baseline and 52 weeks

  • Changes in CSMT from baseline to 104 weeks

    baseline and 104 weeks

  • Number of injections for 52 and 104 weeks

    52 and 104 weeks

  • Injection interval

    52 and 104 weeks.

  • Percentage of patients with injection interval of 12 weeks or more

    104 weeks.

  • +2 more secondary outcomes

Study Arms (1)

treat-and-extend

EXPERIMENTAL

Aflibercept 2mg is injected into the vitreous cavity. An injection is given every 4 weeks five times and then the Treat-and-Extend process begins. If 1mm central subfield macular thickness (CSMT) improved (10% or more reduction) compared to the previous visit, the next treatment will be performed at the same interval. If CSMT is maintained (less than 10% changes), the next interval will be extended by two weeks (up to 12 weeks). If CSMT is worsened (10% or more increase), the next interval will be shortened by two weeks (minimum 4 weeks). If CSMT is stable two times at 12 weeks-interval, the injection will be deferred, and the next visit will be 8 weeks later. These process will be continued for 2 years.

Drug: aflibercept

Interventions

Aflibercept 2mg is injected into the vitreous cavity through the pars plana using 30 gauge needle-attached syringe.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Type I or II diabetes older than 18 years old
  • Patients with DME secondary to diabetes mellitus involving the center of the macula (defined as CSMT \>= 300μm measured using OCT) in the study eye.
  • Decreased visual acuity to 20/40 - 20/300 to be primarily the results of DME in the study eye.
  • Willing and able to comply with clinic visits and study-related procedures, and provide a signed informed consent form.

You may not qualify if:

  • History of vitreoretinal surgery including scleral buckling in the study eye.
  • Laser photocoagulation (panretinal or macular) in the study eye within 90 days of day 1.
  • More than two previous macular laser treatments in the study eye.
  • Previous use of intraocular or periocular corticosteroids in the study eye within 120 days of day 1.
  • Previous treatment with anti-angiogenic drugs in the study eye within 90 days of day 1.
  • Active proliferative diabetic retinopathy in the study eye.
  • History of idiopathic or autoimmune uveitis in the study eye.
  • Cataract surgery within 90 days before day 1 in the study eye.
  • Aphakia in the study eye.
  • Yttrium-aluminium-garnet capsulotomy in the study eye within 30 days before day 1.
  • Vitreomacular traction or epiretinal membrane in the study eye evident biomicroscopically or on OCT that is thought to affect central vision.
  • Current iris neovascularization, vitreous hemorrhage, or tractional retinal detachment in the study eye.
  • Structural damage to the center of the macula in the study eye that is likely to preclude improvement in best-corrected visual acuity (BCVA) following the resolution of macular edema including atrophy of the retinal pigment epithelium, subretinal fibrosis or scar, significant macular ischemia or organized hard exudates.
  • Evidence of infection including infectious blepharitis, keratitis, scleritis, or conjunctivitis in either eye.
  • Uncontrolled glaucoma in the study eye (\>25mmHg) or filtration surgery and/or valve surgery for glaucoma in the past on the study eye.
  • +15 more criteria
