Visual field defect (VFD) is one of the most common impairments that can occur after the brain damage. Different approaches: optical aids, compensatory training and restorative training were extensively evaluated, however each of these therapies still leave much to be desired, since they did not always accomplish the expected result. The aim of the presented case is to demonstrate that optometric vision therapy (OVT) in open space, commonly used in patients with binocular vision disorders, may be an alternative and efficient treatment of VFD, since it focuses on the integration of sensory and motor functions with the strong engagement of visual attention.
This report describes the case of young patient diagnosed with a bilateral tunnel vision defect and central sparing. This was caused by a cyst in the occipital area. OVT was implemented to improve the visual field, accommodation and vergence skills. After 8 months of the therapy (25 in-office sessions with home enhancement) all visual parameters and visual field were in normal range.
OVT appears to be a promising rehabilitation method especially in young patients with acquired brain injury. Further investigation however, of the effect of OVT on the visual field enlargement is needed.
