Sequentially Combined Vitrectomy, IVTA and Macular Focal Laser Photocoagulation for Diabetic Macular Edema

• Status: Completed
• Trial end date: 2007-10-01
• Target enrollment: 0
• Participant gender: All

Summary

Macular edema constitutes the primary cause of visual impairment in diabetic patients with a disease duration of 20 years or more. Intravitreal triamcinolone (IVTA) and macular focal laser photocoagulation were reported to generate favorable results in the treatment of diabetic macular edema, but there have been patients with diffuse diabetic macular edema refractory to such treatment modalities. The present study will test the safety and the efficacy of the combined treatment of vitrectomy, IVTA and macular focal laser photocoagulation in the treatment of intractable diffuse diabetic macular edema.
