Histopathological characteristics of neodymium-YAG laser iridotomy in the human eye.
Light and electron microscopic studies of YAG laser iridotomies were performed in two human iridectomy specimens. Full-thickness defects were created and showed stromal and vascular necrosis. The light and electron microscopic configuration of the lesions was compatible with mechanical disruption from shockwaves. Thermal changes were absent in contrast to iridotomies created by argon laser photocoagulation.
