Core Tip

Core tips: Glaucoma is an irreversible optic neuropathy with the loss of visual field and decrease of vision. The early screening and diagnosis of glaucoma are currently experiencing a demand for anterior segment analysis tools that can gather more information with one short measurement. In this study, we compared the agreement, difference, and correlation of anterior chamber angle parameters such as angel opening distance at 500 μm and trabeculo-iris space area at 500 μm2 measured by anterior segment optical coherence tomography and ultrasound biomicroscopy.
