PUERTAS-BORDALLO, D. et al. Homonymous hemianopia due to arteriovenous malformations of the brain in infancy. Arch Soc Esp Oftalmol [online]. 2007, vol.82, n.10, pp.635-639. ISSN 0365-6691.

Introduction: Arteriovenous malformations (AVM) of the brain have a low prevalence but are responsible for a significant component of visual pathology in the young population. Vascular studies using selective angiography are necessary to identify arterial connections and venous drainage, and provide useful information for planning treatment. Clinical case: A 10-year-old child with a temporo-occipital vascular malformation resulting in a left homonymous hemianopia. Discussion: Arteriovenous malformations of the brain are lesions with a high morbidity and mortality. For the ophthalmologist, they are of special importance due to the possibility of causing a variety of visual defects, depending on their location.
