    Optom Vis Sci 84:775-84. 2007
    ..However, the questionnaire does not meet some psychometric quality criteria. The objectives of this study were first to obtain the factor structure of the VFQ-25, and second, to obtain interval scales by Rasch analysis...

    Maaike Langelaan
    Department of Ophthalmology, VU University Medical Centre, Amsterdam, The Netherlands
    Invest Ophthalmol Vis Sci 47:1817-23. 2006
    ..Although the visual field is generally evaluated using Goldmann isopter III-4e, it has the disadvantage that not all low-vision patients are able to see the stimulus corresponding to this isopter...

    Ruth M A van Nispen
    Department of Ophthalmology, Institute for Research in Extramural Medicine, VU University Medical Center, Amsterdam, The Netherlands
    Optom Vis Sci 84:710-20. 2007
    ..Instead of applying the usual longitudinal methods to assess the outcome of low-vision rehabilitation services in terms of vision-related quality of life, a three-level Item Response Theory (IRT) method was proposed...

    Department of Ophthalmology, Institute for Research in Extramural Medicine, VU University Medical Centre, Amsterdam, The Netherlands
    Int J Rehabil Res 32:12-9. 2009
    ..The results indicate that only age was a predictor for all domains of quality of life. Future research should aim at confirming these results. Ultimately, these findings should lead to adjustments in the rehabilitation programme...

    Maaike Langelaan
    Department of Ophthalmology, VU University Medical Center, Amsterdam, The Netherlands
    Ophthalmic Physiol Opt 25:136-42. 2005
    ..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...
