Evaluation of the Van Herick Technique for Screening for Occludable Angles in an African Population
The current gold standard for screening for angle closure and adopting universal approaches to prophylaxis is the assessment of the anterior chamber (AC) angle by gonioscopy, a technique that has substantial interobserver variability and relies on subjective assessment. Slit-lamp estimation of the peripheral anterior chamber depth (ACD) by the Van Herick technique is a noncontact approach for e...
متن کاملInterobserver reliability when using the Van Herick method to measure anterior chamber depth
INTRODUCTION The Van Herick method is a quick and easy way to estimate anterior chamber depth, which allows grading of patients according to the likelihood of having primary acute closed-angle glaucoma. However, as the test is highly subjective, measurements and thus grading may vary between observers. AIM The aim of this study was to investigate the degree of variation of Van Herick scores a...
متن کاملNoncontact Screening Methods for the Detection of Narrow Anterior Chamber Angles.
PURPOSE Comparing diagnostic accuracy of biomicroscope techniques (van Herick and Smith's tests, evaluating limbal and central anterior chamber depth, respectively) and advanced imaging (Visante OCT and Pentacam) for detection of gonioscopically narrow anterior chamber angles (ACAs). METHODS A total of 78 subjects with narrow or open ACAs underwent four index tests, performed on both eyes by ...
متن کاملA new slit lamp-based technique for anterior chamber angle estimation.
PURPOSE To design and test a new noninvasive method for anterior chamber angle (ACA) estimation based on the slit lamp that is accessible to all eye-care professionals. METHODS A new technique (slit lamp anterior chamber estimation [SLACE]) that aims to overcome some of the limitations of the van Herick procedure was designed. The technique, which only requires a slit lamp, was applied to est...
