Prognosis and Treatment of Visual Field Defects.

Abstract:

:Visual field deficits are common in neurologic disease conditions such as cerebrovascular disease, traumatic brain injury, and brain tumors. Loss of visual fields may lead to impairment of reading skills (hemianopic dyslexia) and limitations of daily activities such as driving, which can have a significant impact on an individual's socioeconomic status and quality of life. Moreover, patients with motor deficits from neurologic diseases have a 20% decreased likelihood of achieving independence in ambulation and self-care activities with coexisting hemianopia. Studies on the natural history of homonymous hemianopia have shown that spontaneous improvement of visual fields may occur in less than 40% of individuals early in the disease process. Improvement is usually incomplete, which implies that a significant number of individuals will be left with a disabling visual deficit. Although several methods of rehabilitation (optical, compensatory, and restitution therapy) are used in practice, none, unfortunately, have shown consistent and significant benefits. In this review, the authors focus on the natural history, impact, prognosis, and treatment modalities for neurologic field defects.
