title: Intractable glaucoma following intravitreal triamcinolone in central retinal vein occlusion.
abstract: OBJECTIVE
  To document secondary glaucoma observed after intravitreal injection of triamcinolone for cystoid macular edema in central retinal vein occlusion.
  
  
  METHODS
  An interventional case series.
  
  
  METHODS
  Retrospective study. The setting was a tertiary care referral institute. Nine patients with central retinal vein occlusion and cystoid macular edema received 4.0 mg/0.1 ml of intravitreal triamcinolone acetate injected through the inferior pars plana under topical anesthesia. Baseline intraocular pressures were normal in all, and no patients had glaucoma.
  
  
  RESULTS
  Seven of the nine patients had a post-injection rise in intraocular pressures, of which one had intractable secondary glaucoma requiring removal of the depot corticosteroid by pars plana vitrectomy combined with trabeculectomy. Two patients were controlled only by maximal medical therapy.
  
  
  CONCLUSIONS
  The occurrence of intractable glaucoma after intravitreal triamcinolone in central retinal vein occlusion is a serious concern and warrants caution in the use of this modality for these patients.
