Visual Field Defects Caused by Craniopharyngioma in 34 Cases
Craniopharyngioma is a common tumor in the sellar region, which accounts for 1.2–3% of the intracranial tumors. It is a benign epithelial tumor and derived from the residual squamous cells in the craniopharyngeal duct. Patients with craniopharyngioma often present a series of systemic symptoms, such as increased intracranial pressure, loss of pituitary function, and damage to the hypothalamic-pituitary axis, thus resulting in hypogonadism, growth retardation, edema, obesity, and diabetes insipidus. Some patients with craniopharyngiomas may be initially admitted to the department of ophthalmology due to decreased vision and visual field defects. This section focuses on the characteristics of visual field defects caused by the craniopharyngioma and introduces the research progresses in the pathogenesis of this disease at the molecular level.
