Historical information

Ophthalmoscopy, also called funduscopy, is a test that allows a health professional to see inside the fundus of the eye and other structures using an ophthalmoscope (or funduscope). It is done as part of an eye examination and may be done as part of a routine physical examination. It is crucial in determining the health of the retina, optic disc, and vitreous humor.

The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination). However, undilated examination is more convenient (albeit not as comprehensive), and is the most common type in primary care.

The Photoscope, or Mirror. Many varieties of the photoscope are in use. .... Some prefer a mirror with a small, folding, protecting handle, or two mirrors, so made that one may serve for the handle while the other is in use. These are easily carried in the pocket, ... If the mirror is perforated in the center, the light rays pass freely to the examiner's eye, but the edge of the perforation, unless perfectly blackened and free from chipping, causes very annoying reflections.
