ABSTRACT
Basic biophysial principles of the eye, such as the retinal projection of the
visual field, bidimensional image inversion, blind point determination, visual
field and retinal quadrants, perimetric principles, and determination of
scotoma, are seen on a working anatomical model of the eye and its visual
field which can be easily constructed at very low cost and from easily
obtained materials: an opaque glass globe, a styrofoam hemisphere, a wood
screen, bulbs, sockets, wire and switches. This model has been used for many
years in our undergraduate medical physiology courses and has replaced the
classical model of candle image inversion by a converging lens.
