We report a combination of surgical techniques during Descemet-stripping automated endoithelial keratoplasty and intraocular lens (IOL) exchange in patients with pseudophakic bullous keratopathy and angle-supported anterior chamber IOLs. During this procedure, the anterior chamber IOL is exchanged for a posterior chamber iris-claw IOL enclavated to the posterior iris; the anterior chamber is ke...

Aim To evaluate the configuration of the anterior chamber angle quantitatively and study the morphological changes in the eye with ultrasound biomicroscopy (UBM) in primary angle closure glaucoma (PACG) patients after laser peripheral iridotomy (LPI). Materials and methods A total of 185 eyes of 185 PACG patients post-LPI and 126 eyes of 126 normal subjects were included in this prospective s...

AIM To evaluate the changes in the anterior segment parameters of the subjects with primary angle closure suspect (PACS) before and after laser iridotomy (LI) using the Pentacam and gonioscopy. METHODS Forty-eight eyes of 48 PACS were included. Anterior chamber angle (ACA), central anterior chamber depth (ACD), anterior chamber volume (ACV) and central corneal thickness (CCT) were recorded fr...

OBJECTIVE This study aims to investigate the changes of anterior chamber morphology after laser peripheral iridotomy (LPI) in primary angle-closure (PAC) patients using Pentacam. METHODS 35 normal persons and 35 patients of PAC before and 1 week after neodymium: yttrium: aluminum garnet (Nd: YAG) LPI were evaluated with Pentacam. We measured the anterior chamber angle (ACA), central anterior ...

Purpose. To investigate age- and position-related changes of anterior chamber angle anatomy in normal, healthy eyes. Patients and Methods. Thirty subjects were separated into a younger and older cohort. The superior and inferior anterior chamber angles of the eyes were measured in supine and sitting positions by ultrasound biomicroscopy (UBM) with bag/balloon technology. Statistical analysis wa...

OBJECTIVE To describe a novel approach to measuring anterior chamber angle dimensions and configurations. METHODS Sixty-nine images were selected randomly from the ultrasound biomicroscopic image database to develop the algorithm. Thirty images were selected for further analyses. The value of each pixel of the 8-bit grayscale ultrasound biomicroscopic images was quantized into 0 (black) or 1 ...

A new computerised method of measurement of the anterior chamber in the human eye is described. Photographs of the anterior chamber were taken with a Zeiss slit-lamp 75-SL and converted from an optical image into a true image by computer with a digitiser. We obtained data on both the anterior chamber volume and also the anterior chamber depth, peripheral anterior chamber volume, the diameter of...

Anterior segment optical coherence tomography (ASOCT) is an imaging modality that provides both quantitative and qualitative information on the cornea, anterior chamber angle, iris and crystalline lens. ASOCT shows excellent repeatability and reproducibility for the measurement of corneal thickness, anterior chamber angle and anterior chamber depth. With realtime video recording, ASOCT can also...
