title: [Comparison of outcomes of conventional laser versus pascal laser for diabetic retinopathy].
abstract: OBJECTIVE
  To assess the efficacy and outcomes of PASCAL laser versus conventional laser for panretinal photocoagulation (PRP) in the treatment of diabetic retinopathy.
  
  
  METHODS
  A retrospective chart review of 26 eyes at Nagoya City University Hospital which had undergone PRP with a follow-up of at least 6 months. The study endpoints were change in visual outcome, central retinal thickness (CRT), laser setting parameters, and total number of PRP and complications.
  
  
  RESULTS
  Ten eyes of conventional laser-treated patients and 16 eyes of PASCAL-treated patients were reviewed. There were significant differences in the laser treating parameters between the PASCAL laser treatment and conventional laser treatment in power, duration, number of sessions and total spot counts including additional treatments (p < 0.01). Among the patients who had undergone PRP in the PASCAL group there was an average of 4195 spots, larger than the conventional laser group (p < 0.0001). There were no significant differences between PASCAL group and conventional laser group in complications and in ability to prevent visual loss and CRT.
  
  
  CONCLUSIONS
  Our data suggested that PASCAL laser might need tighter spacing and more total spot counts to achieve an effect equal to traditional conventional laser treatment.
