About

The purpose of this study is to assess whether preoperative pegaptanib sodium safely improves vitreous hemorrhage prior to surgical intervention and to evaluate the stability of pre-existing tractional retinal detachment.

Full description

Patients undergoing pars plana vitrectomy for active PDR with TRD will receive a single intravitreal pre-operative 0.3mg Macugen™ prior to surgery versus sham injection.

Specific timing of the injection will be at no sooner than 7 days and no longer than 14 days prior to surgery.

Patients will receive a preinjection fundus photo and another post injection photo the day of surgery as dictated by the operative schedule.

Some photos may be limited secondary to vitreous hemorrhage. Follow up visits after surgery will be one day, one week, one month, and three months.
