Subtherhold 532 nm laser

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with central diabetic macular edema Best corrected visual acuity is 20/30 or more
  • Non central Macular thickness more than 250 microns
  • Patients who are able to come for all follow-up

You may not qualify if:

  • Significant renal disease, defined as a history of chronic renal failure requiring dialysis or kidney transplant.
  • Myocardial infarction, other acute cardiac event requiring hospitalization, stroke, transient ischemic attack, or treatment for acute congestive heart failure within 4 months prior to randomization
  • For women of child-bearing potential: pregnant or lactating or intending to become pregnant within the next 3 years.
  • Macular edema is present that is considered to be related to ocular surgery such as cataract extraction
  • Substantial cataract that, in the opinion of the investigator, is likely to be decreasing visual acuity by 3 lines or more
  • History of major ocular surgery (including vitrectomy, scleral buckle, any intraocular surgery, etc.) within prior 4 months or anticipated within the next 6 months following randomization.
  • Exam evidence of severe external ocular infection, including conjunctivitis, chalazion, or substantial blepharitis
