Central retinal artery occlusion and central retinal venous occlusion are rare entities of retinal vascular disorders that can cause sudden visual loss and combined occurrence results in devastating outcomes. The role of protein C deficiency is well established in venous thrombosis however the occurrence of concurrent arterial thrombosis is rare and the combination in association with carotid artery occlusion is an exceptionally rare occurrence. Here we report a case of protein C deficiency presenting as combined central retinal artery occlusion and central retinal venous occlusion with bilateral carotid artery disease

Wallenberg syndrome (lateral medullary syndrome) is a type of posterior circulation stroke resulting in brainstem infarction which is most often caused by occlusion of vertebral artery or posterior inferior cerebellar artery or both.1 Here we report a case of right lateral medullary syndrome secondary to vertebral artery occlusion with associated left cerebellar and cervical cord infarct resulting in quadriparesis.
