Which of the following ophthalmologic condition shows 'vossius ring' during examination?
In traumatic iritis, the inflammatory cells and flare in the anterior chamber, and finely dispersed cellular keratic precipitates on the corneal endothelium. There may be a 'Vossius ring' on the anterior lens capsule. It is a circular ring of brown pigment which occurs due to striking of the contracted pupillary margin against the crystalline lens. It is always smaller than the size of the pupil. Ref: Augsburger J.J., Correa Z.M. (2011). Chapter 19. Ophthalmic Trauma. In P. Riordan-Eva, E.T.
