Fig. 29. Iris and lens capsule have been incarcerated in this limbal wound performed because of cataract surgery. The displaced anatomy completely altered anterior chamber physiology and lead to loss of the eye from intractable glaucoma. Because the material of Descemet's membrane cannot be remodeled by the proteolytic enzymes of the wound healing process, the wound with incarcerated materials such as this will remain unhealed and weak, and will be a possible route for microbial infection.
