Bilateral occlusion of the central retinal artery in a homocystinuric patient: the role of echography.

The authors describe a case presented by a homocystinuric 26-year-old male patient with bilateral occlusion of the central retinal artery. Echography carried out the same day of the occlusion and the following days identified and monitored a mass located in the orbit of the OD. Characteristics and dimension of the mass were confirmed and measured by a CT scan and NMR examination. The orbital mass of the OD appeared to be a swelling of the central retinal artery with echo-refracting opacities, which, in light of recent studies, can be interpreted as multiple arterial thrombi, composed predominantly most likely by platelets. Therapeutic possibilities are discussed.
