title: [Intravitreal bevacizumab versus verteporfin and intravitreal triamcinolone acetonide in patients with neovascular age-related macula degeneration].
abstract: OBJECTIVE
  The aim of this study was to compare intravitreal bevacizumab (IVB) and verteporfin therapy in combination with 4 mg intravitreal triamcinolone (PDT-IVTA) in patients with neovascular age-related macular degeneration (AMD).
  
  
  METHODS
  A total of 30 eyes of 30 patients with neovascular AMD were included in a prospective, randomized study. Ten eyes received PDT-IVTA with a standard light fluence of 50 J/cm(2) (SPDT-IVTA), ten were treated with PDT-IVTA with a reduced light fluence of 25 J/cm(2) (RPDT-IVTA) and ten received IVB. The main outcome was evaluated using early treatment diabetic retinopathy study (ETDRS) visual acuity, fluorescein angiography and optical coherence tomography (OCT) at baseline as well as at day 1, week 1, 1 month and 3 months after therapy.
  
  
  RESULTS
  At the beginning of therapy, the distribution of the groups was balanced. After 3 months, the SPDT-IVTA group showed a non-significant vision loss of seven letters (p<0.3) while a vision loss of 0.5 letters (p<0.9) was found in the RPDT-IVTA group. At the same time, the IVB group had a vision improvement of 11.8 letters (p<0.001). This vision improvement was statistically significant compared to the results of both PDT-IVTA groups (p<0.005). Central retinal thickness (CRT) decreased up to month 3 in the SPDT-IVTA group by 132 microm, in the RPDT-IVTA group by 78 mum and in the IVB group by 138 microm, (p<0.05 in the three groups). No significant difference in the decrease of CRT was found between the treatment groups after 3 months.
  
  
  CONCLUSIONS
  IVB shows significantly better results in vision improvement in the short-term compared to the two PDT-IVTA groups. Within 3 months, all groups showed a comparable decrease in CRT. Long-term follow-up is required to evaluate the safety and treatment efficacy of all treatment modalities.
