## Indications for use
The TOPCON 3D Optical Coherence Tomography 3D OCT-1 (Type:Maestro2) is a noncontact, high resolution tomographic and biomicroscopic imaging device that incorporates a digital camera for photographing, displaying and storing the data of the retina and surrounding parts of the eye to be examined under Mydriatic and non-Mydriatic conditions. The TOPCON 3D Optical Coherence Tomography 3D OCT-1 (Type:Maestro2) is indicated for in vivo viewing, axial cross sectional, and three-dimensional imaging and measurement of posterior ocular structures, including retina, retinal nerve fiber layer, macula and optic disc as well as imaging of anterior ocular structures. It also includes a Reference Database for posterior ocular measurements which provide for the quantitative comparison of retinal nerve fiber layer, optic nerve head, and the macula in the human retina to a database of known normal subjects. The TOPCON 3D Optical Coherence Tomography 3D OCT-1 (Type:Maestro2)is indicated for use as a diagnostic device to aid in the diagnosis, documentation and management of ocular health and diseases in the adult population.
