Acute Blindness in the Elderly With Craniopharyngioma.

The afferent visual system is one of the most common structures involved in patients with craniopharyngioma, and the manifestations include deficits in visual acuity, color vision, and visual fields. Here, we report a case of craniopharyngioma that presented with acute blindness in an elderly man. A healthy 54-year-old man presented with an acute progressive blurring of vision and became blind in six weeks. He developed symptoms of increased intracranial pressure only a week after becoming blind. On examination, visual acuity in both eyes was no perception of light (NPL). He also had left esotropia with restriction of left eye abduction. Both pupils were not responsive to light. The anterior segment was normal in both eyes. Fundoscopy showed bilateral pale optic discs. Computed tomography scan and magnetic resonance imaging revealed a suprasellar mass consistent with craniopharyngioma that compressed the optic chiasma and adjacent brain structures with the presence of hydrocephalus. He underwent uneventful tumor debulking surgery. However, his vision remained NPL postoperatively. Ocular manifestations could be the only symptoms in craniopharyngioma. The delayed presentation may lead to a guarded prognosis.
