TI  - Intra- and interrater agreement and reliability of the Functional Field Score.
PG  - 136-42
AB  - In 2001, the American Medical Association adopted the Functional Vision Score 
      (FVS). It is built on Functional Acuity Scores (FAS) and Functional Field Scores 
      (FFS). The purpose of this study was to evaluate the intra- and interrater 
      reproducibility of the FFS. The study sample was composed of 62 persons, mean age 
      41.8 years, from the population of patients who visited a rehabilitation centre 
      for visually impaired adults. We analysed 30 FFSs of isopter III-4e and 58 of 
      isopter V-4e. Two raters independently scored the plots. The smallest detectable 
      difference (SDD) and the weighted kappa quantified agreement. The SDDs were 
      smaller than the minimal clinically important difference (MCID) of 10 points. 
      Thus, the MCID can be distinguished from measurement error. The intraclass 
      correlation coefficient (ICC) quantified reliability. The intra- and inter ICCs 
      were high (ICCs > 0.98). We concluded that both intra- and interrater reliability 
      of the FFS were excellent.
