Flammer syndrome

Flammer syndrome is a described clinical entity encompassing a group of features caused mainly by dysregulation of blood supply throughout the body, previously known as vascular dysregulation. It can produce symptoms such as cold hands and feet and is often associated with low blood pressure, and in some cases it is associated with, or predisposes a person to, conditions such as normal tension glaucoma. The syndrome is named after the Swiss ophthalmologist Josef Flammer, who first described it.
