Fig. 32. A case of retinal detachment. A. In this case, the iris has become incarcerated into a limbal wound. A series of events leads to total retinal detachment (morning glory detachment). The presence of multiple areas of macrocystic degeneration of the detached retina indicates that the situation is chronic and probably not repairable. B. The histologic section of this case indicates the extent of iris incarceration and the fragility of the wound. (Hematoxylin-eosin stain; × 40.)
