Brief Summary:
The aim of this pilot study was to investigate the effects of an intravitreal combination therapy using triamcinolone and bevacizumab in patients with macular edema due to diabetic retinopathy.

Condition or disease Intervention/treatment Phase
Macular Edema Diabetic Retinopathy Drug: triamcinolone and bevacizumab Phase 3

Detailed Description:
This prospective, monocenter pilot case series was conducted between May 2006 and November 2008. Patients were included because of DME and signs of pre- and early proliferation because of diabetic retinopathy.73 eyes of 56 patients were included, all of which had signed an informed consent to perform a pharmacosurgical procedure consisting of a 23 gauge core Pars Plana Vitrectomy (sutureless single stitch sclerotomy, cutter with 300 cuts/minute) with removement of 1.5ml vitreous and substitution with 1ml BSS, 8mg triamcinolone, and 1.25 mg bevacizumab. At baseline and follow-up, the best corrected visual acuity (BCVA; 6 m Snellen), and intraocular pressure (IOP; Goldmann tonometry), and central macular thickness (optical coherence tomography) were determined. In addition, the need for further treatment and adverse events were monitored.
