RESUMO
CASE PRESENTATION: A 45-year-old woman with a history of seizures, headaches, nausea, vomiting, and decreased visual acuity of 5 years. Visual field detected a bitemporal heteronymous hemianopia. Magnetic resonance imaging revealed basal cistern arachnoiditis and supratentorial hydrocephalus. Cranial computed tomography revealed supratentorial calcifications, scolex in the left occipital region, and hydrocephalus secondary to entrapment of the fourth ventricle. DISCUSSION: Neurocysticercosis can cause bitemporal hemianopsia due to chiasmatic compression secondary to obstructive hydrocephalus. The positivity of anti-cysticercus antibodies determined by ELISA evidence active disease. However patients with hydrocephalus and negative antigen may have sequelae of infection with non-living parasites.

El macroadenoma hipofisiario es un tumor de diámetro superior a 10 mm ubicado en la hipófisis, con una prevalencia del 0,20 % en población viva no seleccionada. Las manifestaciones clínicas incluyen alteraciones visuales tales como defectos en el campo visual (CV) debidos al desplazamiento del quiasma óptico de su posición inicial. La prevalencia de los defectos del CV varía del 32 % al 96 % y generalmente se encuentra hemianopsia bitemporal. Estos pacientes raramente se manejan de manera itegral y son considerados como pacientes con baja visión según la OMS. De aquí la importancia del conocimiento del manejo optpmétrico integral en estos casos.
Pituitary adenoma is a tumor with a diameter greater than 10 mm located in the pituitary gland, with a prevalence of 0.20 % in unselected living population. Clinical manifestations include visual disturbances such as visual field defects due to displacement of the optic chiasm from its normal position. The prevalence of visual field defects varies from 32% to 96%, and bitemporal hemianopsia is typically found. These lesions rarely have a full recovery, and so these patients are categorized as low vision patients according to the World Health Organization; hence the importance of knowing what the optometrist intervention and management are in such cases.
