Schwannoma is a benign tumor of the myelin sheath composed of Schwann cells. It represents from 8 to 10% of all intracranial tumors. The case of a female, 37 years old patient, who attended the Ophthalmology Service because of non-specific pain mostly when performing ocular movements of the eye, proptosis and loss of vision in the left eye, is presented. Physical examination confirmed ocular visual acuity, left eye proptosis of 23 mm, pupillary hypokinesia with a relative afferent pupillary defect and fundus signs of papillary stasis. In imaging studies it was found: exophthalmos of the left eye and retro-ocular hyperdense lesion of 25 x 20 mm. Surgical procedure was performed with biopsy of the lesion. Schwannoma was diagnosed as partially encapsulated. Three months after surgery symptoms and proptosis disappeared. The patient achieved visual and fundoscopic recovery.
