Abstract:
The authors describe 5 patients who developed an orbital pseudotumor as a complication of retrobulbar anesthesia. Allergy tests revealed a hypersensitivity to hyaluronidase, suggesting an immunoallergic etiology of the pseudotumor, which needed to be differentiated from other causes of proptosis after retrobulbar injection.
