The STRATUSOCT™ is a high resolution tomographic device for the viewing and axial cross sectional imaging of posterior ocular structures, It is used for in vivo imaging and measurement of the retinal nerve fiber layer, and optic disk. It is intended for use as a diagnostic device to aid in the detection and management of ocular diseases, including but not limited to macular edema, central serous retinopathy, and glaucoma. The STRATUSOCT™ with Retinal Nerve Fiber Layer ("RNFL") Normative Database is a quantitative tool for the comparison of retinal nerve fiber layer in the human retina to a database of known normal subjects. The RNFL Normative Database is intended for use as a diagnostic aid in the detection and management of ocular diseases, especially glaucoma.

The STRATUSOCT™ with RNFL Normative Database is a microprocessor-based low-coherence digital intrument employing low coherence interferometry to generate images of internal ocular tissue microstructures. The device measures optical reflections or backscatter from tissue using optical beam. Results obtained for Retinal Nerve Fiber Layer can be compared to a database of known normal human subjects.
