Serous Choroidal Detachment Associated with Suspected Contralateral Cavernous Sinus Thrombosis.

ABSTRACT

PURPOSE: To describe a case of choroidal detachment (CD) secondary to cavernous sinus thrombosis (CST). METHODS: Case report. RESULTS: A 73-year-old male with a history of primary open angle glaucoma and pseudophakia presented with retrobulbar pain, blurred vision, and diplopia of the right eye. Exam revealed severe non-hemorrhagic bullous chemosis, tortuous retinal vessels, and elevated intraocular pressure (IOP) in the right eye. Although computed tomography venography findings initially raised suspicion of a carotid-cavernous fistula (CCF), the diagnostic angiogram showed no such evidence, instead raising concern for cavernous sinus thrombosis (CST). Dilated fundus exam and MRI were notable for multiple serous choroidal detachments in the right eye, which resolved with systemic management of CST and topical steroids. CONCLUSION: The possibility of choroidal detachment during the clinical course of a CST should be recognized. CST may be related to impaired venous drainage that forces transudate into perivascular spaces and results in choroidal effusion.
