Visual Field Training

About this app

for people living with post-stroke visual impairments — hemianopia, quadrantanopia, visual neglect, and scotoma. It is not a medical device and does not replace professional rehabilitation. Use it alongside guidance from your neuro-optometrist, stroke rehabilitation team, or low-vision specialist.

Stop and consult your clinician if you experience increased headaches, dizziness, nausea, or visual symptoms during or after exercises.

Our approach to visual rehabilitation

After a stroke, different visual and attentional changes can occur depending on which part of the brain is affected. These exercises target the most common consequences — loss of part of the visual field, reduced awareness of one side of space, and blind spots within the remaining field — using approaches supported by clinical evidence.

The exercises

Hemianopia & Quadrantanopia

• Anchor & Scan — saccadic eye movement training
• Reading Line Scan — visual scanning for reading
• Peripheral Flicker — peripheral awareness stimulation
• Visual Search Grid — systematic scanning practice

Visual Neglect

• Smooth Pursuit — smooth pursuit eye movement training
• Line Bisection — spatial bias calibration
• Visual Search Grid — also used for neglect

Scotoma

• Blind Spot Tracker — awareness training around the blind spot
• Gap Fill — perceptual completion practice

How to use this app

• 15–30 minutes daily, at least 5 days per week, for 4–6 weeks. Two shorter sessions may be more effective than one long one.
• Start with Peripheral Flicker if fatigue is high.
• Show your Progress tab to your therapist at appointments.
• This app works fully offline — no internet needed after first save.

Important

This app is a supplement to professional rehabilitation, not a replacement. Recovery from stroke-related visual field loss varies greatly between individuals. Always follow your clinical team's guidance.

Clinical basis

Hemianopia exercises (Anchor & Scan, Reading Line Scan, Peripheral Flicker, Visual Search Grid) are based on compensatory saccadic scanning training — the approach supported by NICE NG236 and 40+ years of research from Zihl, Kerkhoff, Pambakian, and Trauzettel-Klosinski. Visual neglect exercises (Smooth Pursuit, Line Bisection calibration) follow the smooth pursuit eye movement training tradition recommended by the German Neurological Society guidelines and receiving the highest evidence grade in the Klinke et al. (2015) systematic review. Spatial auditory cues draw on the multisensory stimulation research of Bolognini and Tinelli. Scotoma exercises (Blind Spot Tracker, Gap Fill) provide awareness training and perceptual completion practice around the blind spot area. This complements — but does not replace — the eccentric viewing and Preferred Retinal Locus training offered by low-vision specialists.
