  1. Measuring visual symptoms in British cataract patients : the cataract symptom scale.

    Article - En anglais

    Aims-To develop and validate a scale for the measurement of visual symptoms and functional disability due to cataract in older UK residents.

    Methods-In depth semistructured interviews were undertaken with 44 consecutive patients awaiting cataract surgery.

    Patients were asked to describe visual symptoms and problems with social functioning which were then incorporated into a questionnaire, the cataract symptom scale (CSS).

    The CSS was further examined in a cohort of 118 consecutive cataract patients awaiting surgery.

    Further assessments in these patients included visual acuity, visual function using an existing scale (the VF-14), activities of daily living, perceived health status, anxiety and depression, and a global assessment of how much patients felt their visual symptoms affected their daily life.


    A 15 item scale was derived which was simple to administer to older patients and had a high internal consistency.

    The test-retest correlation coefficient for the total instrument score was r=0.91 (p<0.0001).

    The CSS correlated well with the VF-14 and to a lesser extent with visual acuity in the better eye, activities of daily living, perceived health status, anxiety and depression, and the patients'global assessment of visual symptoms.

    Conclusion-The CSS provides information regarding the symptomatic and functional status of older cataract patients resident in the UK which cannot be obtained by measurement of visual acuity alone.
