Department of Neurosurgery and Neuro-ophthalmology Unit, Hacettepe University School of Medicine, Ankara, TÜRKİYE Visual disturbances are common in patients with craniopharyngioma (CP). Thirty-five patients (17 adults and 18 children) with craniopharyngioma were examined neuro-ophthalmologically. Their visual acuity, visual fields, pupilla and fundoscopic examinations were evaluated in respect to intra-operative tumour localization, and age. Tumour localization and visual acuity were similar in both age groups. Normal fundi were more common in adult group, while papilloedema was more common in the paediatric group. Tumour localization was evaluated in four groups: Group I: intrasellar. Group II: parasellar extension. Group III: suprasellar extension. Group IV: extension into the third ventricle. There were more patients with normal visual acuity in Groups I and II. and more with defective visual fields in Group III. It is important for the ophthalmologist to recognize the visual findings of CP, which are usually the presenting complaint of this tumour.
