Optical Coherence Tomography (OCT). The STRATUSOCT™ is a diagnostic imaging device that provides direct cross sectional images of the retina for measurement and clinical evaluation in the detection of glaucoma and retinal diseases. The STRATUSOCT™ images and analyzes macular thickness, the retinal nerve fiber layer and the optic disc using the latest technology for high resolution scans. This data enhances our ability to diagnose and manage a patient's glaucoma or retinal disease.
