The history of the ophthalmoscope

Documenta Ophthalmologica, 1989
If one were living in 1849 and suffered a central retinal artery occlusion and were examined by the most eminent ophthalmologist of the day, the only diagnosis could be amaurosis or amblyopia. Why? Because visualization of the retina in vivo was still one year away.

On the invention of the ophthalmoscope

Documenta Ophthalmologica, 1994
The author offers an English translation of three passages of Purkinje's Commentatio de examine physiologico organi visus (1823). He shows that Purkinje made three inventions: (1) by using a transparent mirror, (2) by anticipating Maxwellian illumination, and (3) by providing the first recorded ophthalmic examination of animal and human eyes.

The Origin of the Ophthalmoscope

Ophthalmology, 1986
The origin of the ophthalmoscope has been a matter for discussion for many years. Not all the facts are known, and probably never will be, but enough is known to stimulate interested speculation. Helmholtz has been variously described as the "discoverer;" he is said to have "devised" it; and in a recent issue of OPHTHALMOLOGY the Editor refers to ...

EYESi Ophthalmoscope – A Simulator for Indirect Ophthalmoscopic Examinations

2009
We present a training simulator for indirect ophthalmoscopy. An optical tracking system is used to reconstruct the position of a lens mockup and a model of the patient's face. Refraction and illumination are computed in real-time and displayed on a head-mounted display using augmented reality.

Scanning Laser Ophthalmoscope

IEEE Transactions on Biomedical Engineering, 1981
An instrument is described which functions as a low light level ocular fundus camera and ophthalmoscope, and which is capable of making a wide range of quantitative measurements in the eye. Light levels for ophthalmoscopy (20 ?W/cm2 at the retina) are at least two orders of magnitude below those in current use. A focused laser bearn forms a flying spot,
