One of the main problems with glaucoma throughout the world is that there are typically no symptoms in the early
stages. Many people who have the disease do not know they have it and by the time one finds out, the disease is usually
in an advanced stage. Most retinal cameras available in the market today use sophisticated optics and have several other
features/capabilities (wide-angle optics, red-free and angiography filters, etc) that make them expensive for the general
practice or for screening purposes. Therefore, it is important to develop instrumentation that is fast, effective and
economic, in order to reach the mass public in the general eye-care centers. In this work, we have constructed the
hardware and software of a cost-effective and non-mydriatic prototype device that allows fast capturing and plotting of
high-resolution quantitative 3D images and videos of the optical disc head and neighboring region (30° of field of view).
The main application of this device is for glaucoma screening, although it may also be useful for the diagnosis of other
pathologies related to the optic nerve.
