What is an ophthalmoscope?
This illuminated instrument is used for visualizing the interior of the eye. A direct ophthalmoscope provides a magnified (15x) upright view with a small field of view and consists of a bright light source and incorporated focusing lenses. An indirect ophthalmoscope creates an inverted, magnified (3x) image of the fundus projected in front of the eye, with a wide field of view and consists of a bright light source and a hand-held high-plus lens.
