TLDR
This paper is an attempt to evaluate the clinical application of laser iridotomy from the results of treating more than forty eyes.Abstract:
Extensive experience with animals has shown that it is possible to irradiate the iris with a ruby laser without damage to the cornea, lens, or retina (Hallman, Perkins, Watts, and Wheeler, I 968, I969). The possible use of a laser to make an iridotomy for therapeutic purposes was appreciated by Flocks and Zweng (i964), and Zweng, Flocks, Kampany, Silbertrust, and Peppers (I964) reported two attempts to perform this in human eyes. In neither case was a complete iridotomy produced, but holes were produced in two pigmented irides by Zweng, Paris, Vassiliadis, Rose, and Hayes (I970). Some success in treating a small series of cases of closed-angle glaucoma and secondary glaucoma due to iris bombe has been reported (Perkins, I970, I971), and this paper is an attempt to evaluate the clinical application of laser iridotomy from the results of treating more than forty eyes.read more

The response of the rabbit eye to laser irradiation of the iris
TL;DR: Intravenous injection of a carbon suspension or fluorescein afforded evidence that the increased permeability to plasma protein occurs in the ciliary processes and not in the iris, and prevented prostaglandin formation.

Continuous Wave Argon Laser Iridectomy in Angle-Closure Glaucoma
TL;DR: By using a continuous wave argon laser in a multiburn fashion, successful iridectomies were achieved in 42 out of 45 phakic eyes with either acute or chronic angle-closure glaucoma, although long-term evaluation of this modality of therapy is presently unavailable.

TL;DR: Pupillary-block glaucoma is the first postoperative complication seen following the implantation of an intraocular lens, and in this series occurred at an incidence of 3-8%.

Laser Iridotomy for Aphakic Pupillary Block
TL;DR: In six patients with aphakic pupillary block, argon laser produced full-thickness iridotomies that succeeded in restoring anterior chamber and intraocular pressure to normal.

Neodymium: YAG laser iridotomy
TL;DR: Although longterm follow-up of large numbers of patients is lacking, Nd:YAG laser iridotomy appears to be a safe and effective alternative to Argon laser iriridotomy in selected patients.

Laser Photocoagulation of the Iris
TL;DR: A method for producing iridotomy in the tan-brown iris by ruby photocoagulation had a high success rate and was directly related to the degree of iris pigmentation.
