Laser iridotomy functions to relieve pupillary block by allowing an equalization of pressure between the anterior and posterior chambers. Patients should have had nonindentation gonioscopy that demonstrated contact between the iris and the trabecular meshwork typically for greater than 180° of the angle, although clinician discretion may be employed on

Laser peripheral iridotomy (LPI) is a procedure for managing angle-closure glaucoma caused by relative or absolute pupillary block. LPI eliminates pupillary block by allowing the aqueous to pass directly from the posterior chamber into the anterior chamber, bypassing the pupillary opening.

Peripheral Iridotomy Using Nd:YLF Laser
Ophthalmic Surgery, Lasers and Imaging Retina, 1992ABSTRACT We used the Nd:YLF Oscillator/Regenerative Amplifier Laser (ISL, San Diego, Calif) at 1053 nm to perform peripheral iridotomies in three eyes. The total amount of energy required was greater than the usual amount needed in Nd:YAG peripheral iridotomies.

Results of neodymium-YAG laser iridotomy in 34 eyes with narrow drainage angles are reported. Irido-tomies appeared patent on slit-lamp examination in 32 (94%) eyes. Complications included failed patency of iridotomy and acute elevation of intraocular pressure.

Laser Iridotomy in Closed-Angle Glaucoma
Archives of Ophthalmology, 1979An argon laser iridotomy was performed on 53 eyes of 34 patients with closed-angle glaucoma. Technically, all of the iridotomies were successful. Blue irides were more resistant to treatment than brown irides. The iridotomies were performed with high energy of 2 W and a very short exposure time of 0.01 to 0.04 s, thus minimizing thermal damage to ...

In Reply. —In Dr Belcher's letter, a few points were raised that are of historical interest, and I am grateful for these astute amendments. Indeed, Dr Meyer-Schwickerath performed "photocoagulation" and the laser was not invented until 1960. It seems that Dr Zaret has, to some extent, suffered the same fate as Carl Adolph von Basedow and Caleb Hiller ...

Technique for testing the patency of laser iridotomies
Acta Ophthalmologica, 1986Abstract With laser iridotomy it may often be difficult to achieve total penetration of the iris, particularly in very light or very dark irides. It may be impossible to determine with the slit‐lamp whether a small laser iridotomy is functionally penetrating.

Nd:YAG laser iridotomy in uveitic glaucoma
Clinical & Experimental Ophthalmology, 2001ABSTRACT Purpose: To determine the survival of Nd:YAG laser peripheral iridotomy in those patients with angle closure glaucoma and iris bombé associated with uveitis. Methods: A retrospective review was performed on 11 patients of the Ocular Immunology Clinic of the Royal Victorian Eye and Ear Hospital who presented with uveitis, iris bombé due to ...

Malignant Glaucoma after Laser Iridotomy
Ophthalmology, 1992Malignant glaucoma was initially reported as developing after surgery for glaucoma. Subsequently, associations with trauma, inflammation, and the use of miotic agents, as well as spontaneous occurrence have been noted. Laser iridotomy has been assumed to avoid the risk of subsequent malignant glaucoma in eyes with angle-closure glaucoma by avoiding ...

Q switched Neodymium:YAG Laser Iridotomy
Ophthalmology, 1984Twenty phakic eyes of 19 patients underwent Q-switched neodymium:YAG laser iridotomies for angle-closure glaucoma. Eleven eyes were previous argon laser failures. Penetration was achieved in each case with several shots in one session. Complications were minor and transient.
