title: Triamcinolone-assisted 3D-vitrectomy in diabetic vitreomacular traction.
abstract: OBJECTIVE
  To evaluate the efficacy of triamcinolone as an aid in vitreous visualization during 3D-vitrectomy for the treatment of diabetic vitreomacular traction.
  
  
  METHODS
  Prospective interventional study in patients with symptomatic vitreomacular traction. Pre- and postoperative assessments included visual acuity, retinography, intraocular pressure and optical coherence tomography. All patients were operated by the same surgeon (OOMJ). Triamcinolone was used as a visual enhancer during surgery. The parameters of the vitreophage (Accurus 800CS, Alcon) were set to the 3D-system (dual dynamic drive), contact lenses (plain and wide angle) being used for visualization. Peripheral 360 masculine vitreous circumcision at high cut rate was performed, carefully releasing the vitreomacular adhesion at the posterior pole by means of an appropriate pic or vitreoretinal forceps.
  
  
  RESULTS
  The sample consisted of five consecutive patients (five eyes), three female and two male, with symptomatic vitreomacular traction. Their age ranged from 54 to 71 years (mean 62.6 +/- 6.3 years). During the surgical procedure, the areas with vitreomacular traction were properly visualized and identified after the application of triamcinolone. No complications were recorded during or after surgery. There was a statistically significant improvement in visual acuity after the surgical procedure (p=0.0313).
  
  
  CONCLUSIONS
  Triamcinolone facilitates the surgical treatment of vitreomacular traction by improving visibility of both the vitreous humor and the vitreous-retina interface. Triamcinolone-assisted 3D vitrectomy proved to be an effective procedure in these cases.
