Vossius ring
Vossius ring (also called Vossius's ring or Vossius' ring) is due to blunt trauma to the eye. During injury to eye a circular ring of fainted or stippled opacity is seen on the anterior surface of the lens due to brown amorphous granules of pigment lying on the capsule. It has the same diameter as of the contracted pupil and is due to impression of iris on the lens produced by the force of concussion injury which drives the cornea and iris backward.
