Ophthalmoscopy

 

a method of examining the interior, or fundus, of the eye. Ophthalmoscopy requires a magnifying glass, a light source, and an ophthalmoscope, which is a mirror with a hole in the center for directing a beam of light within the eye. Complex electrical ophthalmoscopes are also manufactured; these are equipped with their own light source and optical systems.
