Aortic dissection presenting as uniocular blindness

A patient presented with uniocular blindness and headache, which was initially suspected to be subarachnoid hemorrhage. The patient had a seven-year history of diabetes mellitus, hypertension and hypothyroidism, as well as a two-year history of congestive cardiac failure with aortic regurgitation. Upon autopsy, the patient was diagnosed with aortic dissection. There are no other known reports of such a presentation. This case demonstrates that aortic dissection can present without any classical features, and hence it is important to consider the possibility of dissection in patients with long-standing hypertension and acute neurologic symptoms associated with pain.
