Flammer syndrome is a recently described clinical entity comprising a complex of clinical features caused mainly by dysregulation of the blood supply which has previously been called vascular dysregulation. It can manifest itself in many symptoms such as cold hands and feet and is often associated with low blood pressure. In certain cases it is associated with or predisposes for the development of diseases such as a normal tension glaucoma.[1] Flammer syndrome is named after the Swiss ophthalmologist Josef Flammer.
