title: [Assessment of visual acuity in patients with age-related macular degeneration 1 year after photodynamic therapy].
abstract: OBJECTIVE
  To evaluate visual acuity in patients who underwent photodynamic therapy (PDT) for exudative age-related macular degeneration (AMD).
  
  
  METHODS
  138 eyes undergoing PDT were studied retrospectively. 101 eyes with AMD (AMD group) and 37 eyes with polypoidal choroidal vasculopathy (PCV group) were evaluated.
  
  
  RESULTS
  In the AMD group, one year after PDT, the log MAR visual acuity improved by 2 lines or more in 23 eyes (22.8%), and decreased by 2 lines or more in 27 eyes (26.7%). In the PCV group, one year after PDT the log MAR visual acuity improved by 2 lines or more in 13 eyes (35.1%), and decreased by 2 lines or more in 8 eyes (21.6%). Out of the 138 eyes, 30 eyes showed improvement in visual acuity by 0.6 or more, one year after PDT (AMD group : 17 eyes; PCV group: 13 eyes)
  
  
  CONCLUSIONS
  Patients with PCV who had good primary visual acuity improved their visual acuity by 0.6 or more one year after PDT.
