We present a patient with known metastatic ACC presented with a rapidly declining vision with visual acuity oculus dexter (OD) equal to counting fingers at two feet. On imaging, she was found to have a right orbital apex tumor causing compressive optic neuropathy. She received the intensity modulated radiation therapy (IMRT). After completion of the therapy, she had regained essentially a full vision with visual acuity OD of 20/30 without corrective lenses. The treatment rationale and pertinent literature are discussed in this article.en-USAttribution 3.0 United StatesAdenoid cystic carcinomaCompressive optic neuropathyIntensity modulated radiation therapyLoss of visionOrbital metastasisRecovery of visionArticle
