title: Argon laser iridotomy in the treatment of patients with primary angle-closure or pupillary block glaucoma: a clinicopathologic study.
abstract: A "pulsed" argon laser was successful in 48 of 64 (75%) attempted laser iridotomies. Scanning and transmission electron microscopy performed on specimens taken at varying intervals following laser treatment revealed progressive scarring of iris tissue. The complications appear minimal at this time, but longer follow-up is required before it can be stated that laser and surgical peripheral iridectomies are comparable. However, the laser's simplicity and ease of administration appear to warrant its continued use at this time.
