Clinical Significance of Tumor-Related Edema of Optic Tract Affecting Visual Function in Patients with Sellar and Suprasellar Tumors.

Objective: Preoperative tumor-related edema of the optic tract (EOT) is often found along the white matter tract of the visual system. However, the relationship of EOT with visual function and outcome remains unclear. Therefore we aimed to elucidate whether the presence of EOT is associated with visual outcome in patients with sellar and suprasellar tumors.
