A 51-year-old woman with Sneddon's disease presented with transient right hemifield loss of vision and transient right-sided weakness. Over the preceding decade she had experienced a slow decline in mental function. She also had hypertension, migraine, and a mixed seizure disorder. She had skin changes typical for generalized livedo reticularis but she did not have Raynaud's phenomenon or winter ulcerations. Her disease was not understood until the stroke-related symptoms were associated with the skin abnormalities. We review the neuro-ophthalmic manifestations of Sneddon's disease and add data from our case to the growing body of fact that suggests that Sneddon's disease may be an immunologically mediated vasculopathy.
