Prophylactic laser peripheral iridotomy and cataract progression
Eye, 2010To determine whether prophylactic laser peripheral iridotomy (LPI) for primary angle closure (PAC) is associated with cataract progression.In 1999, Mongolian volunteers aged>or=50 years were invited to participate in a longitudinal study. Glaucoma was excluded in all participants and 712 of them were selected to undergo a full ophthalmic examination as

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

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.

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.

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 ...

Ophthalmic Epidemiology
Laser peripheral iridotomy (LPI) is largely used as the first course of action to treat primary angle-closure (PAC). Previous literature has long been divided on the relationship between iridotomy position and dysphotopsia onset. The current study investigates whether there is a correlation between iridotomy position, temporal versus superior, and new ...

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 ...

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.

Picosecond Neodymium: Yttrium Lithium Fluoride (Nd:YLF) Laser Peripheral Iridotomy
American Journal of Ophthalmology, 1995We evaluated the picosecond neodymium:yttrium lithium fluoride (Nd:YLF) laser for performing peripheral iridotomies of predetermined size and shape in various types of irides.In the first part of the study, we determined operating parameters from performing 60 iridotomies in human cadaver eyes.
