title: [Study of the effect of intravitreal dexamethasone implant in pseudophakic macular edema. Preliminary].
abstract: OBJECTIVE
  To evaluate the efficacy of intravitreal dexamethasone implant on the treatment of pseudophakic macular edema (PME).
  
  
  METHODS
  A retrospective, observational, descriptive study was conducted on 4 patients who received an intravitreal injection of dexamethasone implant due to PME in the period from 1st January 2013 to 31st December 2013 in the Hospital Universitario de La Ribera (Alzira, Valencia, Spain). A complete ophthalmic examination was performed on these patients. Best-corrected visual acuity (BCVA), macular thickness), and duration of the effect of the treatment were studied.
  
  
  RESULTS
  At baseline, the mean MT was 414μm. After dexamethasone implant, mean values of MT decreased to 330.25μm at month one. The mean change from baseline MT was 83.75μm. The baseline mean BCVA was 0.3 and improved to 0.575 at month one and 3. The mean duration of the effect of the treatment was 3.5 months.
  
  
  CONCLUSIONS
  Intravitreal dexamethasone implant is a possible treatment for Irvine-Gass syndrome as it improved visual acuity and reduced the macular thickness of these patients.
