Raeder's syndrome was first described by the Norwegian ophthalmologist J.G. Raeder in 1918 and again in 1924 by the same author. The seminal report was a description of a young male patient with unilateral periocular pain combined with ipsilateral miosis and ptosis, and with slight objective signs of trigeminal nerve involvement. Autopsy demonstrated a tumour at the base of the skull in the middle cranial fossa. Raeder coined the term "paratrigeminal" for the reported clinical picture. Later case reports by Raeder and other authors have included patients experiencing a more benign clinical course, some with spontaneous remissions, with unilateral periocular pain and ipsilateral signs of oculosympathetic paresis as the common denominator. This article is a chronological survey of the main contributions to the medical literature. Various definitions of the syndrome are outlined, including the more recent classification, as well as some pathophysiological and prognostic considerations.
