AB  - INTRODUCTION: Glaucoma is one of the leading causes of irreversible blindness 
      worldwide and can have a significant impact on patient quality of life and 
      vision-related functioning. The Glaucoma Quality of Life 15 (GQL-15) 
      questionnaire is a disease-specific instrument to evaluate and quantify 
      functional impairment of patients with glaucoma. This study evaluated the German 
      version of the GQL-15 including correlations with perimetric parameters. METHODS: 
      A German version of the GQL-15 containing 15 items was developed and evaluated in 
      98 patients with glaucoma in different stages of the disease. The GQL-15 results 
      were correlated with the perimetric parameters mean deviation (MD) and pattern 
      standard deviation (PSD) of the better and worse eye. Classical and probabilistic 
      test analyses (Rasch model) were performed. RESULTS: The mean GQL-15 value was 
      77.3 +/- 21.7 (SD) and most items of the GQL-15 correlated significantly with the 
      MD of the worse eye (r = -0.416; p = 0.0014) and the better eye (r = -0.304; p = 
      0.02). There was also a highly significant correlation between glaucoma-specific 
      QoL and visual acuity. A short version containing nine items yielding a higher 
      psychometric performance can also be used. CONCLUSIONS: The German version of the 
      GQL-15 is a potent instrument to evaluate impairment in vision-specific 
      functioning of patients with glaucoma. The GQL-15 values are better correlated 
      with the sensitivity of the eye with the more severe glaucomatous damage. The 
      data can help for a better understanding of individual patient impairment to 
      improve medical advice and therapy of patients with glaucoma.
