Hediger A Landau K Chaloupka K 2008 BACKGROUND Tumours in the superior orbital region can cause hypoglobus. We compare the pre- and postoperative globe position in two patients with different tumour types. HISTORY AND SIGNS A 29-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 orbit is of importance regarding the degree of reversibility of the accompanying hypoglobus. https://sonar.ch/global/documents/280426 eng info:eu-repo/semantics/altIdentifier/doi/10.1055/s-2008-1027308 info:eu-repo/semantics/altIdentifier/pmid/18454387 Klinische Monatsblatter fur Augenheilkunde. - 2008 Adenoma Adult Eye Diseases Female Hemangioma Humans Male Middle Aged Orbital Neoplasms Hypoglobus due to tumours in the superior orbital region. http://purl.org/coar/resource_type/c_6501
