Changes in Visual Field Defect : Post-Pituitary Tumor Resection Comparison Between Transphenoidal and Transcranial Approaches

To compare patients with pituitary adenoma who underwent transphenoidal (TS) and transcranial (TC) surgery, the visual outcome and postoperative complications. Retrospective analysis of case notes of 45 patients {(90 eyes) 14 TC, 31 TS} with pituitary adenoma who underwent pituitary tumour resection between 1998 and May 2002. The patients’ age ranged from 16 to 66 years with a mean ± SD of 41.7 ± 31.1 years. 56% are male. Fourteen patients were operated by TC. Preoperatively, visual acuity deficit occurred in 64% vs 96% (TS vs TC, p =0.011).
