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 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.

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

Malignant Glaucoma After Laser Peripheral Iridotomy
Journal of Glaucoma, 2019Purpose: We describe a patient with primary angle-closure glaucoma who developed malignant glaucoma following laser peripheral iridotomy. Methods: A 58-year-old male presented with peripheral and central anterior chamber shallowing following an uncomplicated Nd: YAG laser peripheral

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 to define threshold values, which may ...

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.
