Iris Bombe

Iris Bombe

Iris bombe is a condition in which there is apposition of the iris to the lens or anterior vitreous, preventing aqueous from flowing from the posterior to the anterior chamber. The pressure in the posterior chamber rises, resulting in anterior bowing of the peripheral iris and obstruction of the trabecular meshwork. This may result in an acute attack of angle closure glaucoma. Also note in this photograph a Seton tube inferiorly that is occluded by the iris bowing forward and the iris contacting the corneal endothelium peripherally.
