An ophthalmoscope is an instrument that enables a doctor to examine the inside of a person's eye. The instrument has an angled mirror, various lenses, and a light source. With it, a doctor can see the retina, the optic nerve, the retinal veins and arteries, and certain problems that can affect the vitreous humor (the jellylike substance in the eye).
