Unilateral lid retraction during pregnancy.

A 32-year-old woman noted left lid retraction during pregnancy. Examination revealed unilateral enophthalmos without symptoms of diplopia or sinus disease. Orbital imaging showed characteristic features of the silent sinus syndrome, which were confirmed intraoperatively. The clinical and imaging attributes of this syndrome are discussed, including possible mechanisms of disease development. Management strategies are summarized. A brief discussion of the differential diagnosis of enophthalmos is also included.

Lung cancer, proptosis, and decreased vision.

A 48-year-old man presented to the emergency department with a 3-day history of decreased vision in a painful proptotic right eye. The patient was being treated with chemotherapy and radiation for non-small cell lung carcinoma. Examination showed visual acuity of hand motions, decreased motility, and an afferent pupillary defect on the right, consistent with an orbital apex syndrome. Neuroimaging revealed "dirty" orbital fat and no paranasal sinus disease. Orbital biopsy initially showed only fibrosis; however, on subsequent biopsies, nonseptate hyphae later identified as mucormycosis was recovered. The patient survived with exenteration and systemic amphotericin B.

Progressive visual loss and ophthalmoplegia.

A 51-year-old woman with hyperthyroidism presented with a 4-week history of bilateral progressive visual loss despite treatment with oral prednisone. Her visual function improved after bilateral orbital decompression. The indications for and advantages and disadvantages of radiation therapy and orbital decompression in TAO are discussed. The management of intraocular pressure, strabismus, and lid abnormalities in TAO is also addressed.
