High-Definition Optical Coherence Tomography Imaging of the Iridocorneal Angle of the Eye
Objective To assess the ability of high-definition optical coherence tomography (HD-OCT) to image the anterior chamber angle. Methods Forty-five consecutive subjects with phakic eyes underwent gonioscopy and anterior chamber angle imaging with HD-OCT adapted with a 60-diopter aspheric lens mounted over the imaging aperture. The patients' fixation was directed to the side using an external fixation light, and scans were taken of the temporal and nasal quadrants. The visibility of angle structures was assessed and the diagnosis of angle closure using HD-OCT was compared with that of gonioscopy. Results The majority of subjects were Chinese (91.1%) and female (62 ...
