The PC-based treatment approach was originally developed by Prof. Zihl (1988, 1990) and has since been used with various modifications in 13 studies on a total of 551 patients with homonymous visual field loss and persistent visual disabilities.

The main outcome of saccadic training is a significant improvement in visual search performance accompanied by more efficient oculomotor strategies, and a reduction in visual disability as assessed by standardized questionnaires and behavioural measures. These include measures of improvements in navigation skills and object finding. The efficacy of this treatment approach to improving of visual overview and visual exploration is superior to practice with reading (Schuett et al., 2012), non-specific visual training (Roth et al., 2009), standard occupational therapy (Mödden et al., 2012) or counselling with regards to coping strategies (Zihl, 2011). Importantly, time since brain injury (Zihl, 2011) and age of hemianopic patients (Schuett & Zihl, 2012) do not play a significant role in the treatment effect.
