Abstract:
A 27-year-old woman with a known suprasellar dermoid cyst and stable idiopathic intracranial hypertension (IIH) presented with new monocular vision change and new-onset headaches. Formal visual field testing accurately identified progressive chiasmal compression due to her suprasellar dermoid cyst before radiographic change was appreciable on magnetic resonance imaging. Accurate interpretation of her visual field findings avoided the common pitfall of attributing new visual symptoms to her IIH diagnosis. This case highlights the value of recognizing visual field changes that localize to the chiasm even in patients with history of other ophthalmologic conditions.
