Abstrakt:	Aim This study addresses the examination of the factorial validity of the National Eye Institute Visual Function Questionnaire 39 (NEI-VFQ 39) and the neuro-ophthalmological supplement in a German sample. Method Eighty-one patients with visual field defects affecting at least one eye answered the NEI-VFQ 39 and the supplement. Theoretical factor structures reported in the manuals were examined in confirmatory factor analysis. Because of a misfit, items retained after item analysis were subjected to exploratory factor analysis. Results The originally postulated factor structures could not be replicated. Many items revealed floor effects. The 21 remaining items could be assigned to two factors - "visual functioning" and "socio-emotional impairment". Conclusion The weakness of the theoretical factors can be avoided by using the 2-scale model. (Georg Thieme Verlag KG Stuttgart · New York.)
