Acute central retinal artery occlusion associated with livedoid vasculopathy: a variant of Sneddon's syndrome.

Livedoid vasculopathy (LV) is characterized by a long history of ulceration of the feet and legs and histopathology indicating a thrombotic process. We report a case of acute central retinal artery occlusion in a 32-year-old woman who had LV. She showed no discernible laboratory abnormalities such as antiphospholipid antibodies and no history of cerebrovascular accidents. Attempted intra-arterial thrombolysis showed no effect in restoring retinal arterial perfusion or vision. The central retinal artery occlusion accompanied by LV in this case could be regarded as a variant form of Sneddon's syndrome, which is characterized by livedo reticularis and cerebrovascular accidents.
