Clinical history
88-year-old who died of nonocular causes. A surgical procedure had been performed at age 60.
Diagnosis
The surgical procedure was an iridencleisis. This is a type of glaucoma filtering procedure that is no longer used because of the risk of sympathetic ophthalmia. In this procedure, iris is intentionally pulled into the surgical wound so that it will never seal up the connection between the anterior chamber and the subconjunctival tissue. Aqueous humor will continually drain from the anterior chamber to the conjunctival substantia propria, forming a filtering bleb that is seen on the slide. Other manifestations of glaucoma are the attenuated ganglion cell layer of the retina and the deep cup of the optic nerve head. KEY WORDS: surgery, filtration surgery, glaucoma, optic atrophy.
