title: Safety and efficacy of intravitreal triamcinolone acetonide for uveitic macular edema.
abstract: BACKGROUND
  To evaluate the safety and efficacy of intravitreal triamcinolone acetonide (TA) for treating macular edema secondary to non-infectious uveitis.
  
  
  METHODS
  Retrospective review of sixteen patients (20 eyes) with chronic cystoid macular edema (CME) as a consequence of controlled intermediate uveitis, posterior uveitis, or panuveitis who received at least one intravitreal injection of TA. Main outcome measures were visual acuity (VA), intraocular pressure (IOP), formation or progression of an existing cataract, and CME resolution during the follow-up period.
  
  
  RESULTS
  At last follow-up, VA showed improvement (compared to baseline) in 11 eyes (55%), deterioration in three eyes (15%), remained completely unchanged in one eye (5%), and showed improvement initially but returned to baseline levels in five eyes (25%). At last follow-up, CME had relapsed or was still present in 10 of the eyes (50%). The remaining eyes showed complete resolution of the CME, without evidence of recurrence during the follow-up time. Mean VA at last follow-up showed statistically significant improvement (p = 0.02) in nonvitrectomized eyes (mean baseline VA: 1.14 +/- 0.58; mean final VA: 0.96 +/- 0.66) compared to the almost unaltered mean visual acuity for vitrectomized eyes (mean baseline VA: 0.76 +/- 0.41; mean final VA: 0.71 +/- 0.48)(p = 0.40, paired samples t-test). Elevation of IOP was transient in all cases and responded well to topical medications, except for one patient who required placement of an Ahmed valve. Preexisting cataract progressed in three of the 15 phakic eyes (20%). One patient developed a retinal detachment and required additional surgery to reattach it. Patients were followed for a mean of 34 weeks (median: 32 weeks; range: 19-56 weeks).
  
  
  CONCLUSIONS
  Intravitreal TA may play a role in the treatment of uveitis-related CME. Further controlled studies are necessary to test this hypothesis.
