Eligibility Criteria

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

You may qualify if:

  • persistent new vessels,defined as fine retinal vessels with dilated buds or tips covered with hemorrhage or associated with recurrent vitreous hemorrhage or paucity of accompanying fibrous tissue and/or increased in extent compared to previous visit,unresponsive to complete panretinal laser photocoagulation performed at least 4 months prior;
  • logarithm of minimum angle of resolution (logMAR) best-corrected visual acuity of 0.17 (Snellen equivalent, 20/30) or worse.

You may not qualify if:

  • history of vitrectomy in the study eye;
  • history of thromboembolic event (including myocardial infarction or cerebral vascular accident);
  • major surgery within the prior 6 months or planned within the next 28 days;
  • uncontrolled hypertension;
  • known coagulation abnormalities or current use of anticoagulative medication other than aspirin.
