چکیده
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 the ACD. Shallow ACD defined as less than 2.4 mm. evaluated by five-fold cross-validation test in hold-out testing dataset. also it against two glaucoma specialists. performance calculated metrics, including accuracy, sensitivity, specificity, area under receiver operating characteristic curve (AUC). Results total 3753 (1720 AC 2033 images) were assigned training dataset, 1302 (509 793 held out internal datasets. In achieved an AUC 0.86 (95% CI, 0.83–0.90) with 80% sensitivity 79% specificity. same better specialists (accuracy vs. accuracy 74 69%).

Iridotrabecular contact observed using anterior segment three-dimensional OCT in eyes with a shallow peripheral anterior chamber.
PURPOSE To evaluate the prevalence and range of iridotrabecular contact (ITC) in eyes with a shallow peripheral anterior chamber (AC) by using anterior segment swept-source optical coherence tomography (AS-SS-OCT) and to compare the results with those obtained with ultrasound biomicroscopy (UBM) and gonioscopy. METHODS Forty-three shallow peripheral AC eyes in 43 consecutive patients underwen...
متن کاملAnterior chamber depth during hemodialysis
BACKGROUND Exacerbation of chronic glaucoma or acute glaucoma is occasionally observed in patients undergoing hemodialysis (HD) because of anterior chamber depth changes during this therapy. PURPOSE To evaluate anterior chamber depth and axial length in patients during HD sessions. METHODS A total of 67 eyes of 35 patients were prospectively enrolled. Axial length and anterior chamber depth...

PURPOSE To compare the ocular anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter, as measured with two different Scheimpflug imaging devices. METHODS This transversal study included 80 right eyes from 80 subjects aged from 20 to 40 years. Their spherical equivalents ranged from -4.25 to +1.00 diopters (D). Each eye's anterior chamber depth, white-to-wh...
متن کاملDepth of anterior chamber after cataract extraction.
A total of 80 patients with senile cataract had the anterior eye chamber depth measured optically by means of Haag-Streit's attachment II. The distance to the pupillary border was 2.59 +/- 0.05 mm (mean +/- SEM) preoperatively. It increased gradually after cataract extraction to 3.33 +/- 0.04 mm, measured 4 months after the operation. The increase of depth was the greatest in patients with a fl...
