Bilateral choroidal detachment and fluctuating proptosis secondary to bilateral dural arteriovenous fistulas treated with transcranial orbital decompression with resolution: report of a case.

BOTH SPONTANEOUS CHOROIDAL DETACHMENT AND DURAL ARTERIOVENOUS fistulae of the cavernous sinus are uncommon clinical entities. Each pro-duces a relatively characteristic syndrome manifest by a constellation of ocular signs and symptoms. We believe their occurrence together has been previously reported in the literature on only a single occasion.' We have recently had the opportunity to study extensively a patient with this rare clinical combination. The results of this investigation have led us to believe that this association may not be as unusual as the literature would suggest. It is our plan, by presentation of this case in detail, to indicate a plausible basis for the relationship of spontaneous choroidal detachment to dural arteriovenous fistulae in the region of the cavernous sinus.
