Vossius Ring

is a circular deposit of pigment resulted from blunt trauma that forms a complete or incomplete ring on the anterior lens capsule surface.Vossius ring is a well-circumscribed complete or incomplete ring of pigment deposition on the anterior lens capsule surface, usually as a result of significant blunt eye trauma. The disease was first described by Vossius in 1903, at which time he discussed both a pigmented variety of the ring and a non-pigmented variety that he thought was the result of degeneration of anterior lens epithelial cells. The non-pigmented form is no longer considered to be a Vossius ring.
