title: Intravitreal triamcinolone acetonide in exudative age-related macular degeneration.
abstract: OBJECTIVE
  To examine the effects of intravitreal injection of 4.0 mg triamcinolone acetonide on the visual and clinical course of exudative age-related macular degeneration.
  
  
  METHODS
  A randomized clinical trial of a single injection of triamcinolone acetonide into the vitreous cavity of experimental eyes at baseline versus observation of untreated subjects was performed in 27 patients followed up for 6 months. Inclusion criteria included exudative age-related macular degeneration with subfoveal or occult choroidal neovascularization, and visual acuity between 20/40 and 20/400. Examination, acuity assessment, fundus photography, and fluorescein angiography were performed at baseline and at 3 and 6 months after enrollment. LogMAR visual acuity was compared between groups by a repeated measures analysis of variance model. Masked assessment of photographic studies was performed and groups were compared with Fisher's exact test.
  
  
  RESULTS
  Visual acuity was significantly better in the treated group compared with control subjects at 3 and 6 months (P < 0.005). Fundus photography and angiography were more likely to show stability or improvement at 3 and 6 months in the treated group (P = 0.05). Intraocular pressure elevation was seen in 25% of treated patients, but was controlled with topical medications. Progression of cataract was more frequently seen in the treated group.
  
  
  CONCLUSIONS
  Intravitreal triamcinolone acetonide may provide short-term improvement in visual acuity and fundus findings in exudative macular degeneration. These findings must be considered preliminary and should be followed by multicenter, masked, placebo-controlled trials with long-term follow-up.
