Background: Tumours in the superior orbital region can cause hypoglobus. We compare the preand postoperative globe position in two patients with different tumour types.
History and Signs: A29-year-old man and a 58- year-old woman presented with pronounced hypoglobus. In both patients time-scale and importance of the lesion were comparable. Imaging suggested a pleomorphic adenoma in the younger patient, whereas the female patient was radiologically diagnosed with a hemangioma.
Therapy and Outcome: Both radiological diagnoses could be histologically proven. Both lesions were excised in toto. The adenoma patient showed a full recovery of the preoperatively reduced vision. However, the hypoglobus persisted even after ten months. The hemangioma patient had an immediate full recovery of her hypoglobus.
Conclusion: The histological type of a tumor in the superior orbita is of importance regarding the degree of reversibility of the accompanying hypoglobus.
