title: Pituitary adenoma and visual function. The prognostic value of clinical, ophthalmological and neuroradiologic findings in 51 patients subjected to operation.
abstract: The series studied included 51 patients subjected to operation for pituitary adenoma. The visual status was analysed both pre- and postoperatively. The pre- and postoperative parameters were compared with clinical information, ophthalmological and neuroradiological findings with a view to an evaluation of their prognostic value. In 36 patients with chromophobe adenoma, visual field defects were present in 92% before the operation; visual function improved in 62% and returned to normal in 24%. Among 15 patients with eosinophil or mixed adenoma, only two (13%) had visual field defects pre-operatively. In those patients where operation was followed by a distinct visual improvement, the pre-operative ophthalmological findings were as follows: visual acuity greater than 6/24, normal optic discs, visual field defects up to two quadrants, and pneumoencephalographic findings suggestive of only a small suprasellar tumour.
