Purpose To describe a case of a patient with acute systemic lupus erythematous (SLE) causing choroidal effusions and to report a novel technique for evaluation of the choroidal fluid which sheds light on effusion pathogenesis. Observations A 37 year-old woman was referred for decreased vision, eye pain and shortness of breath. The patient had bilateral angle closure glaucoma from choroidal effusions and bilateral pleural effusions. Work-up revealed new onset acute SLE. A technique for obtaining suprachoroidal fluid is described, and the fluid was analyzed using Light's criteria and found to be exudative in nature. Conclusions and importance There has been speculation as to pathogenesis of choroidal effusions in a variety of conditions, and many authors believe the most likely process to be transudative. The exudative nature of the fluid in our patient suggests that choroidal effusions in acute SLE are likely caused by inflammation, and not secondary to hypoalbuminemia or another transudative process. Similar analyses of suprachoroidal fluid in other disease processes may help elucidate the underlying pathogenesis and may possibly guide treatment.
