Positional variation of the ciliary ganglion and its clinical relevance

Ciliary ganglion is one of the peripheral parasympathetic ganglion situated near the apex of the orbit betweenlateral rectus and optic nerve. During routine dissection of a human cadaver for the medical students at KasturbaMedical College, Manipal, India, we found a rare and unreported case, where, the ciliary ganglion was placedbetween the medial rectus and the optic nerve, lateral to the ophthalmic artery. In this report we also discussthe course, relations of the branches/roots of the ganglion, histological study and the clinical relevance of thispositional variation.
