Visual Improvement Following Stereotactic Radiosurgery for Orbital Apex Vascular Tumor.

Orbital apex lesions represent a clinical challenge since they are difficult to remove surgically and may induce significant functional defects. The orbital apex is an area of convergence of neurovascular elements passing through the various local osseous foramina and the congestion of several critical anatomical structures in a confined space increases the risk of intraoperative complications. Radiotherapy is an alternative treatment option in such cases but may also induce radiation toxicity. We present a case of a vascular orbital apex lesion, which caused vision loss and was treated with stereotactic radiosurgery, resulting in significant visual restoration.
