The purpose was to document changes in attentional visual field (AVF) over time and analyse the possible baseline characteristics predicting a decline in AVF size over time. Data was taken from a sample of 968 individuals. The authors found a significant loss of horizontal and average AVF from baseline to two years follow-up. No significant loss of vertical AVF was noted. A greater than five degree decline in AVF score over two years was significantly associated with lower baseline scores of visual search and executive function, visual acuity and visual field, history of stroke and depression at baseline, and being female.
