The provided text offers a comprehensive overview of homonymous hemianopia (HH), a visual impairment resulting from brain damage affecting the visual pathways. It explains the neurological basis of HH, detailing how lesions in specific brain regions lead to characteristic patterns of vision loss, such as macular sparing or quadrantanopia. The sources discuss the primary causes of HH, with stroke being the most common, followed by traumatic brain injury and tumors, and outline the diagnostic process from initial suspicion to confirmation via neuroimaging. Furthermore, the text addresses the profound functional and psychosocial impact of HH on daily life, including challenges with mobility, reading (hemianopic alexia), and the occurrence of associated perceptual phenomena like visual neglect and Charles Bonnet Syndrome. Finally, it explores the prognosis and management strategies, highlighting the limited potential for true vision restoration versus the effectiveness of compensatory rehabilitation methods, optical aids, and the complex considerations surrounding driving and HH in children.
