AIM To establish normative values for the anterior segment in normal infants and children in relation to age. METHODS Anterior segments were measured in 46 normal infants and children (21 males and 25 females, aged from 1 to 60 months (mean 17.09 (SD 16.99) months)), by use of ultrasound biomicroscopy. RESULTS Anterior chamber depth, trabecular-iris angle, angle opening (trabecular-iris) di...

PURPOSE To investigate anterior segment parameters in obese patients in comparison to healthy individuals. METHODS Thirty-four obese subjects and 34 age-sex-matched healthy subjects were enrolled in this prospective cross-sectional study. Ophthalmological examinations including intraocular pressure (IOP), central corneal thickness (CCT), anterior chamber depth (ACD), anterior chamber volume (...

Purpose: To evaluate the associa on between baseline ocular variables and the opening of the anterior chamber angle by laser peripheral iridotomy (LPI) in primary angle closure suspects (PACS) using a new Fourier-domain swept-source anterior segment op cal coherence tomography (FD-ASOCT). Method: Sixty-six PACS eyes of 41 individuals were included in this prospec ve interven onal case series. A...

Purpose. To measure the anterior chamber volume (ACV) and determine factors associated with the ACV in healthy Chinese adults. Methods. In this cross-sectional study, we used swept-source optical coherence tomography (SS-OCT) to measure ACV and other anterior segment parameters. Factors associated with ACV were also determined. Results. A total of 313 healthy Chinese adults were enrolled. The a...

Recent papers have presented correlations between the radius of curvature of the anterior lens surface and anterior chamber depth (Lowe, I972), and between the anterior lens radius and the anterior and posterior corneal radius (Lowe and Clark, I973). This paper presents measurements of anterior lens radius in relation to age, lens thickness, and axial length in two series comprising 9I normal e...

PURPOSE The aim of this study was to investigate the factors associated with decreases in corneal endothelial cell density (ECD) resulting from cataract surgery in eyes with pseudoexfoliation syndrome (PEX). METHODS The clinical records of 78 eyes of 78 patients with PEX who had undergone cataract surgery were reviewed. ECD was measured preoperatively and at 3 months postoperatively with spec...

BACKGROUND Myopia subjects usually have long axial lengths and are predisposed to deep anterior chamber depths and open angles. Jiangning eye study is a randomized, population based study in Shanghai to determine whether myopia has an effect on the prevalence of occludable angles. METHODS A total of 2478 residents aged 50 years and over were randomly selected, and 2044 (82.5%) individuals of ...
