Long-Term Risk and Prediction of Progression in Primary Angle Closure Suspect. [PDF]

JAMA Ophthalmol
ImportanceIdentifying primary angle closure suspect (PACS) eyes at risk of angle closure is crucial for its management. However, the risk of progression and its prediction are still understudied in long-term longitudinal studies about PACS.ObjectiveTo explore baseline predictors and develop prediction models for the 14-year risk of progression from ...

Resident-performed laser peripheral iridotomy in primary angle closure, primary angle closure suspects, and primary angle closure glaucoma

Clinical Ophthalmology, 2017
To investigate the power use and complication frequency of resident-performed laser peripheral iridotomy (LPI).A retrospective analysis of 196 eyes from 103 patients who underwent neodymium: yttrium-aluminum-garnet laser iridotomy performed by resident physicians from January 1, 2010 through April 30, 2015 at a university-based county hospital was done.

Cataract progression after Nd:YAG laser iridotomy in primary angle-closure suspect eyes [PDF]

British Journal of Ophthalmology, 2022
Background/AimsProphylactic laser peripheral iridotomy (LPI) is performed in primary angle-closure suspect (PACS) eyes to prevent acute angle-closure attacks. However, accelerated cataractogenesis is a potential risk of the procedure that may result in decreased visual acuity.
