The occupational therapist selects one or more frame of reference or treatment approach for the guidelines and clinical reasoning of the treatment plan. People with hemianopia will be involved throughout the study. Various scanning training strategies may be employed, including ocular motor exercises for improved accuracy of pursuits and saccades, including large saccades into the affected side, developing an organized horizontal or vertical method to scan for a target, and identifying targets on the affected side while walking or multitasking.

This may also explain why we see that some patients with recent visual field loss, who do not need optical visual field expanders because saccadic movements alone compensate well while others are struggling years after the original field loss and greatly benefit from optical visual field expanders. Scanning laser ophthalmoscopy (SLO) with microperimetry allows the investigator to observe simultaneously a display of the retina, a fixation cross and the presented stimulus.
