RESULTS: The mean vault values after the first month were 349.93 μm. They remained stable during the first 24 months of the follow-up period, with a slight tendency to decrease at 36 months which was not statistically significant. We observed a reduction in the anterior chamber angle, depth and volume of 14.23°, 167 μm and 60.44 mm3, respectively. This reduction remained stable during the follo...

Objectives: to evaluate the anterior chamber depth (ACD), axis length (AL), and relationships between ACD AL in high myopia patients. Objects methods: a descriptive study was conducted on 168 eyes (88 patients, ≥12 years old) diagnosed with (more than -6D). Results: average degree, ACD, were -8.75±2.61D, 3.72±0.20 mm, 27.33±1.49 respectively. There no statistical signification degree (r=0.044; ...

We reviewed a series of recently published studies in which the anterior chamber depth (ACD) distance was measured by Pentacam or Pentacam HR and compared with other measuring devices. Since some published studies reach contradictory conclusions regarding device interchangeability and include di erent ocular conditions, for instance, phakic eyes, pseudophakic eyes, cataractous eye, and so on, t...

Our purpose is to correct digital CCD-recorded Scheimpflug photographs, imaging both the anterior and posterior corneal surface, the anterior chamber, and the anterior eye lens surface for optical distortions. In a ray-tracing algorithm the imaging of the posterior corneal surface in a given Scheimpflug photograph is corrected by applying Snell's law on parallel incident rays entering through t...

Abstract Background The purpose of this study was to implement and evaluate a deep learning (DL) approach for automatically detecting shallow anterior chamber depth (ACD) from two-dimensional (2D) overview segment photographs. Methods We trained DL model using dataset photographs collected Shanghai Aier Eye Hospital June 2018 December 2019. A Pentacam HR system used capture 2D eye image measure...

PURPOSE Studying the role of ultrasound biomicroscopy (UBM) in detection of anterior segment changes in infants with primary congenital glaucoma (PCG). METHODS Cross-sectional study that included 25 eyes of 15 patients suffering from PCG and a control group of 15 eyes of ten age- and sex-matched participants. Diagnosis of PCG was based on clinical data (intraocular pressure, corneal diameter,...

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...

AIM To study the effects of gender, eye side and age on anterior chamber measurements; To compare the anterior chamber parameters between glaucoma and normal subjects. METHODS A total of 169 patients (299 eyes), of which 122 normal subjects (218 eyes), 24 cases (39 eyes) with primary angle-closure glaucoma (PACG) and 22 cases (42 eyes) with primary open-angle glaucoma (POAG) visiting our hosp...
