title: Trans-tenon retrobulbar triamcinolone injection for macular edema associated with branch retinal vein occlusion remaining after vitrectomy.
abstract: OBJECTIVE
  To evaluate the effectiveness and safety of trans-Tenon retrobulbar triamcinolone injection for macular edema associated with branch retinal vein occlusion (BRVO) after vitrectomy.
  
  
  METHODS
  Prospective interventional case series.
  
  
  METHODS
  The study included 20 eyes of 20 patients with BRVO, characterized by macular edema lasting more than 3 months after vitrectomy. Trans-Tenon retrobulbar injection of 40 mg triamcinolone was performed, and visual and anatomic responses were evaluated.
  
  
  RESULTS
  Mean foveal thickness was 499.4 +/- 209.1 microm preoperatively, 281.8 +/- 110.1 microm at 2-week follow-up, and 196.9 +/- 92.1 microm at 6-month follow-up (P < .0001, at 2 weeks and 6 months, paired t test). Improvement of visual acuity by at least 0.2 logMAR (logarithm of the minimum angle of resolution) was seen in 14 (70%) of the 20 eyes.
  
  
  CONCLUSIONS
  Trans-Tenon retrobulbar injection of triamcinolone may be an alternative for additional treatment of eyes with BRVO that remains after vitrectomy.
