Anterior Chamber Angle Assessment Techniques
The anterior chamber angle is the actual anatomical angle created by the root of the iris and the peripheral corneal vault. Within it lie the structures involved in the outflow passage of the aqueous, namely the trabecular meshwork and the Schlemm’s canal (figure 1). The depth of the angle in a healthy eye is approximately 30°, with the superior part usually less deep than the inferior half. Ho...
متن کاملAnterior segment imaging in angle-closure disease
Introduction Angle-closure disease (both primary and secondary) is a spectrum of disorders characterized by iridotrabecular contact obstructing aqueous outflow. Anterior segment imaging plays an important role in understanding the pathophysiology of angle closure, diagnosis, and monitoring the treatment, especially in challenging cases. Indirect gonioscopy, the gold standard for visualizing the...
متن کاملAnterior-segment imaging for assessment of glaucoma.
This article summarizes the physics, technology and clinical application of ultrasound biomicroscopy (UBM) and optical coherence tomography (OCT) for assessment of the anterior segment in glaucoma. UBM systems use frequencies ranging from approximately 35 to 80 MHz, as compared with typical 10-MHz systems used for general-purpose ophthalmic imaging. OCT systems use low-coherence, near-infrared ...
متن کاملUse of EyeCam for imaging the anterior chamber angle.
PURPOSE To compare EyeCam (Clarity Medical Systems, Pleasanton, CA) imaging with gonioscopy for detecting angle closure. METHODS In this prospective, hospital-based study, subjects underwent gonioscopy by a single observer and EyeCam imaging by a different operator. EyeCam images were graded by two masked observers. The anterior chamber angle in a quadrant was classified as closed if the trab...
متن کاملDynamic analysis of dark-light changes of the anterior chamber angle with anterior segment OCT.
PURPOSE To describe the use of anterior segment optical coherence tomography (OCT) in studying the dynamic dark-light changes of the anterior chamber angle. METHODS Thirty-seven normal subjects with open angles on dark-room gonioscopy and 18 subjects with narrow angles were analyzed. The dynamic dark-light changes of the anterior-chamber angle were captured with real-time video recording. The...
