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.

The effects of iridotomy size and position on symptoms following laser peripheral iridotomy
American Journal of Ophthalmology, 2005To evaluate visual disturbances following laser peripheral iridotomy (LPI). Patients sometimes note visual disturbances following laser peripheral iridotomy. The purpose of this study was to provide what we believe to be the first systematic evaluation of these visual disturbances, including a determination of whether or not they are associated with ...

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 Changes Anterior Chamber Architecture
European Journal of Ophthalmology, 2016Purpose The pressure gradient between anterior and posterior chamber in acute angle closure (AAC) and primary angle closure suspects is balanced by a sufficient laser peripheral iridotomy (LPI). The anterior chamber changes induced by LPI in patients with unilateral AAC were examined and compared to healthy eyes

Lens Dislocation Following Yag Laser Peripheral Iridotomy
Ophthalmic Surgery, Lasers and Imaging Retina, 2010A rare case where laser peripheral iridotomy resulted in crystalline lens dislocation into the vitreous cavity. The patient was managed with pars plana vitrectomy, fragmatome lensectomy, anterior chamber intraocular lens and surgical iridotomy with a final best corrected visual acuity of 6/9.

Progression of Peripheral Anterior Synechiae After Laser Iridotomy
American Journal of Ophthalmology, 2005To determine the incidence and to characterize the risk factors of peripheral anterior synechiae (PAS) progression after laser iridotomy (LI).Retrospective observational cohort study.The extents of pre- and postlaser PAS and ocular and systemic data were obtained from the charts of 54 primary angle-closure glaucoma patients (59 eyes), all of whom had ...

Semiconductor Diode Laser Peripheral Iridotomy
Archives of Ophthalmology, 1990To the Editor. —The ruby, argon, and neodymium-YAG lasers have each been used as an alternative to surgical iridectomy for the purpose of creating an opening in the iris. The semiconductor diode laser is a small, portable, light-weight laser that uses standard current and is air cooled.

Laser peripheral iridotomy across the spectrum of primary angle closure
Canadian Journal of Ophthalmology, 2007To study the effectiveness of Nd:YAG laser peripheral iridotomy (LPI) for primary angle closure in Asian Indian patients.Retrospective analyses of patients who underwent LPI and completed a minimum follow-up of 2 years. Eyes were classified as primary angle-closure suspects (PACS), primary angle closure (PAC), and primary angle-closure glaucoma (PACG).

Diode Laser-Pumped, Frequency-Doubled Neodymium:YAG Laser Peripheral Iridotomy
Ophthalmic Surgery, Lasers and Imaging Retina, 1997* BACKGROUND AND OBJECTIVE: The solid state, continuous-wave, frequency-doubled neodymium:yttrium-aluminum-garnet (Nd:YAG) laser pumped by a diode laser has several advantages, including air cooling, higher electrical to optical efficiency ratios, portability, and the use of standard 110-V AC electrical service.

Neodymium:YAG Laser Peripheral Iridotomy: Cause of a Visually Incapacitating Cataract?
Ophthalmic Surgery, Lasers and Imaging Retina, 2006<P>Neodymium:YAG (Nd:YAG) laser peripheral iridotomy is the procedure of choice to treat and avoid further episodes of angle-closure glaucoma. A patient who developed a visually incapacitating posterior subcapsular lens opacity shortly after Nd:YAG laser peripheral iridotomy is described. The patient underwent cataract surgery and achieved a good
