Light and electron microscopy of the anterior iris surface in eyes with and without pseudo-exfoliation syndrome

The anterior iris surface of 12 human eyes were studied by light and electron microscopy. Seven of these specimens were from eyes with capsular glaucoma, whereas the remaining 5 served as controls. In light microscopic sections large extracellular aggregates appeared within the anterior iris surface of the glaucomatous eyes, and in some cases such deposits formed a 25 μ broad zone along the anterior iris border. In the electron microscope these extracellular aggregates turned out to be pseudo-exfoliation material. It seems that the amounts of pseudo-exfoliation deposits within the anterior iris surface increase parallel with the progress of glaucoma.
