[Visual field defects after cerebral lesions from the patient's perspective: health- and vision-related quality of life assessed by SF-36 and NEI-VFQ] Nervenarzt. 2008 Feb;79(2):185-94 Authors: Gall C, Mueller I, Kaufmann C, Franke GH, Sabel BA BACKGROUND: In patients with visual field defects, measurement of health-related quality of life (hQoL) and vision-related quality of life (vQoL) is an important adjunct to clinical measures such as perimetry. The purpose of this study was to describe hQoL and vQoL of patients with visual field defects after cerebral lesions such as infarction, traumatic brain injury, and tumor. METHODS: The National Eye Institute -- Visual Function Questionnaire (NEI-VFQ) for vQoL and the SF-36 Health Survey for hQoL were administered to 24 patients about 2 years after occurrence of the visual field defect. Visual fields were measured by standard perimetry and a near-threshold campimetric method. Visual acuity was measured by the Landolt-Ring-Test. RESULTS: The NEI-VFQ scores -- but not SF-36 scores -- were not only lower than those of a disease-free group but also lower than those of patients with visual impairments not caused by cerebral damage. Rank correlations between the size of the visual field defect and NEI-VFQ subscales were significantly high or modest. With SF-36 scores these correlations were generally low and moderate at best. CONCLUSION: The NEI-VFQ is a valuable measure of self-reported visual impairment in patients with visual field defects after cerebral lesions. The measurement of unspecific hQoL is not sufficient to reflect the problems of patients with visual field defects. PMID: 17934709 [PubMed - indexed for MEDLINE]
