Long-term structural changes of the anterior visual pathway after pituitary tumor resection

Optical coherence tomography has become a standard component in the neuro-ophthalmological assessment of patients with pituitary tumors. In particular, preoperative structural measurement of the anterior visual pathway has been shown to be predictive of early post-operative visual recovery in patients with compressive neuropathy. However, the course of long-term outcome remains heterogeneous with a subset of patients experiencing progressive dysfunction even after complete decompression of the optic apparatus. The purpose of this study was to characterize the long-term structural changes of the anterior visual pathway in patients who underwent pituitary tumor resection.
