Erratum

In the article that appeared on page 259 of the September 2015 issue of the Journal of Neuro-Ophthalmology, a sentence within the Results section listed the wrong reference. The corrected sentence and reference are below.

Linking the reported difficulties to the ICF: Classifying the reported difficulties according to the ICF linking rules (21) resulted in 268 concepts for the open-ended question and 248 concepts for the standardized questionnaires.

Additionally, the following sentence within the Results section had a link to the incorrect Supplemental Digital Content table. The corrected link is below.

During the process of linking these concepts, in 4 of 516 concepts, no unanimous decision was reached, and the fourth evaluator was involved in the decision process, resulting in agreement (see Supplemental Digital Content, Table E4, http://links.lww.com/WNO/A211).

Original Contribution

Background: Homonymous visual field defects (HVFD) are common after postchiasmatic acquired brain injury and may have a significant impact on independent living and participation in society. Vision-related difficulties experienced in daily life are usually assessed using questionnaires. The current study 1) links the content of 3 of these questionnaires to the International Classification of Functioning, Disability and Health (ICF) and 2) provides analyses of vision-related difficulties reported by patients with HVFD and minimal comorbidities.

Methods: Fifty-four patients with homonymous hemianopia or quadrantanopia were asked about difficulties experienced in daily life because of their HVFD. This was performed during a structured interview including 3 standardized questionnaires: National Eye Institute Visual Functioning Questionnaire, Independent Mobility Questionnaire, and Cerebral Visual Disorders Questionnaire. The reported difficulties were linked to the ICF according to the ICF linking rules. Main outcome measures were presence or absence of experienced difficulties.

Results: The ICF linking procedure resulted in a classification table that can be used in future studies of vision-related difficulties. Besides well-known difficulties related to reading, orientation, and mobility, a high proportion of patients with HVFD reported problems that previously have not been documented in the literature, such as impaired light sensitivity, color vision, and perception of depth.

Conclusions: A systematic inventory of difficulties experienced in daily life by patients with HVFD was performed using the ICF. These findings have implications for future study, assessment and rehabilitation of patients with HVFD.
