The dexamethasone suppression test for the diagnosis of Cushing syndrome in a patient with central serous chorioretinopathy.
To describe a case whereby the dexamethasone suppression test was used to diagnose Cushing syndrome in a patient presenting with central serous chorioretinopathy. A 60-year-old woman presented with central serous chorioretinopathy and was investigated with the dexamethasone suppression test; the result was positive and lead to a diagnosis of an adrenal tumor. The adrenal tumor was removed and her central serous chorioretinopathy resolved. The dexamethasone suppression test can be used safely in an outpatient procedure to investigate cases of central serous chorioretinopathy, and it may be a useful screening tool in these patients.
