Primary Outcome Measures :
  1. A Change Between Two Time Points is Reported for Maximum Reading Speed [ Time Frame: Month 12 ]
    A change between two time points (Baseline and 12 months) is reported for Maximum Reading Speed.

Secondary Outcome Measures :
  1. Change in Activity Productivity [ Time Frame: Month 12 ]
    To evaluate the mean change in activity impairment from baseline to 12 months using and activity impairment questionnaire. Scale is from 0-10 with 0 being lowest (no effect on my daily activities) and 10 being highest (completely prevented me from doing my daily activities).

  2. Change in Visual Acuity [ Time Frame: Month 12 ]
    To determine the mean change in best-corrected visual acuity on ETDRS visual acuity chart at a starting distance of 4 meters from baseline. Visual function of the study eye was assessed using the ETDRS protocol, which is a widely accepted international standard. A higher letter score represents better functioning.

  3. Change in Contrast Sensitivity [ Time Frame: 12 months ]
    To measure the mean change in contrast sensitivity scores on Pelli-Robson charts from baseline. Scale in assessing the log of the contract sensitivity score (CS score) is from 0-2.25, with 0 being no letters read on the contrast sensitivity chart, and 2.25 being all letters read on the contrast sensitivity chart. Total CS score = [(total # letters correct - 3) x 0.05].

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Ability to provide written informed consent and comply with study assessments for the full duration of the study
  • Age 18 ≤ x ≤ 65 years and currently employed at the baseline study visit
  • Diagnosis of diabetes mellitus (type 1 or 2)

    o Any one of the following will be considered to be sufficient evidence that diabetes is present:

  • Current regular use of insulin for treatment of diabetes
  • Current regular use of oral anti-hyperglycemia agent for the treatment of diabetes
  • Clinical evidence of retinal thickening due to macular edema involving the center of the macula, associated with diabetic retinopathy.
  • Central diabetic macular edema present on clinical examination or or evidence indicating disease activity on spectral domain OCT.
  • Visual acuity score greater than or equal to 19 letters (20/400) and less than or equal to 73 letters (20/40) by the ETDRS visual acuity protocol.
  • Media clarity, pupillary dilation and patient cooperation sufficient to allow OCT testing and retinal photography

Exclusion Criteria:

  • Pregnancy (positive pregnancy test) or known to be pregnant; also pre-menopausal women not using adequate contraception.
  • Participation in another ocular investigation or trial simultaneously
  • Blood pressure > 180/110 (systolic above 180 OR diastolic above 110)
  • Any condition that, in the opinion of the investigator, would preclude participation in the study (e.g. chronic alcoholism, drug abuse)
  • Evidence of vitreoretinal interface abnormality after ocular exam or OCT that may be contributing to the macular edema
  • An eye that, in the investigator's opinion, has no chance of improving in visual acuity following resolution of macular edema (e.g. presence of subretinal fibrosis or geographic atrophy)
  • Presence of another ocular condition that may affect the visual acuity or macular edema during the course of the study (e.g. AMD, uveitis, Irvine-Gas)
  • Evidence of active neovascularization of the iris or retina
  • Evidence of central atrophy or fibrosis in the study eye
  • Presence of substantial cataract, one that might decrease the vision by 3 or more lines of vision at sometime during the study.
  • Previous use of intraocular or periocular corticosteroids in the study eye in the previous 120 days
  • Previous treatment with anti-angiogenic drugs in the study eye i.e. pegaptanib sodium, bevacizumab, ranibizumab, aflibercept within 120 days prior to baseline
  • History of vitreous surgery in the study eye
  • History of cataract surgery within 3 months of enrollment.
  • History of YAG capsulotomy within 2 months of enrollment.
  • Visual acuity <20/400 in the fellow eye
  • Uncontrolled glaucoma (pressure >30) despite treatment with glaucoma medications.
  • History of cerebral vascular accident or myocardial infarction within 3 months prior to Day 0.
