We describe a novel stereocamera for particle image velocimetry (PIV) applications that incorporates the Scheimpflug condition that the object plane, lens plane, and image plane must be collinear. We examined the governing equations for this system using a computer-based sensitivity analysis to predict the accuracy of the in-plane and out-of-plane measurement. We evaluated the performance of th...

PURPOSE To investigate changes in anterior chamber depth (ACD), corneal volume (CV), anterior chamber angle (ACA), anterior chamber volume (ACV), central corneal thickness (CCT), horizontal visible iris diameter (HVID), pupil diameter (PD), and intraocular pressure (IOP) after uneventful phacoemulsification cataract surgery with intraocular lens implantation. METHODS A total of 132 eyes of 13...

Primary angle-closure glaucoma (PACG) is a major form of glaucoma in Asia. It is a leading cause of blindness worldwide. Laser peripheral iridotomy (LPI) is the standard firstline intervention in both acute and chronic forms. It is successful in preventing recurrence of acute attacks and virtually eliminates the risk of an acute attack in the fellow eye. Peripheral iridotomy eliminates pupillar...

BACKGROUND The purpose of this study was to compare the accuracy of the new Sirius(®) Scheimpflug anterior segment examination device for measurement of central corneal thickness (CCT) and anterior chamber depth (ACD) with that of CCT measurements obtained by ultrasound pachymetry and ACD measurements obtained by ultrasound biometry, respectively. METHODS CCT and ACD was measured in 50 right ...
