title: [Acute blepharoptosis caused by fibrous dysplasia].
abstract: We report a case of fibrous dysplasia revealed by acute ptosis in a 38-year-old patient. Ophthalmologic examination disclosed a moderate right ptosis. The rest of the results were strictly normal except for a known facial asymmetry. Visual acuity was 20/20 in both eyes, there was no extrinsic or intrinsic oculomotor disorder, and funduscopy was normal. Given this acute presentation, emergency cerebral imagery was carried out, providing a diagnosis of fibrous dysplasia with orbital and cavernous repercussions, with no sign of cerebral disorder or obvious vascular lesion. Progression was marked by a regression of the ptosis. Fibrous dysplasia is a rare pathology but presents varied clinical presentations. The authors present the broad characteristics of this pathology and the management of an acquired ptosis. They discuss the possible mechanisms involved in the drop of the right upper eyelid of this patient and the therapeutic solutions.
