Abstract
Pituitary tumours are a common cause of functional impairment and degeneration of
the anterior visual pathway. Depending on localization and size, they clinically manifest
as initially reversible visual field defects. As part of interdisciplinary tumour
management, ophthalmologic examinations are of particular importance concerning diagnostics,
indication for tumour resection and documentation of functional surgical results.
Based on the relationship between clinical dysfunction and manifest atrophy, together
with the patientʼs age and the duration of symptoms, the ophthalmologist can provide
insights into the postoperative visual prognosis. Under good conditions, surgical
tumour resection often results in significant improvements to visual fields and acuity.
Long-term ophthalmological controls are required in cases of persistent visual loss,
radiotherapy or tumour remnants abutting the visual pathway.
