Ultrasound biomicroscopic measurement of development of anterior chamber angle.
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...
متن کاملUltrasound biomicroscopic measurement of anterior chamber angle in premature infants.
AIM To establish normative values for the anterior segment in premature infants in relation to postconceptional age and birth weight. METHODS Anterior segments were measured in 39 premature infants, 25 to 39 weeks' gestational age by use of ultrasound biomicroscopy and a muscle hook with topical anaesthesia. RESULTS Anterior chamber depth, trabecular-iris angle, angle opening (trabecular-ir...
متن کاملUltrasound biomicroscopic measurement of anterior chamber biometry between before and after pupil dilation in children.
PURPOSE To evaluate anterior chamber biometry of the eyes of normal children using ultrasound biomicroscopy (UBM) and to evaluate the differences in biometry between children and adults, and before and after pupil dilation in children. METHODS Anterior chamber depth (ACD) and trabecular-iris angle (TIA) were measured in 94 normal children and 15 normal adults using UBM. Before and after pupil...
متن کاملMeasurement of Anterior Chamber Angle with Optical Coherence Tomography
Evaluation of the width of the anterior chamber angle and its inlet during the ophthalmic examination is essential in determining the susceptibility of the angle to closure (KalevLandoy et al 2007, Leung et al 2007, Leung et al 2008, Radhakrishnan et al 2005). There are factors that have been recognized as affecting the anterior chamber angle width include age, race/ethnicity, iris color, eye d...
متن کاملNovel approach for anterior chamber angle analysis: anterior chamber angle detection with edge measurement and identification algorithm (ACADEMIA).
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 ...
