The art of phoneoscopy - using the smart phone to image the eye.
Direct “phoneoscopy” images - iPhone XSmax
WELCOME to the home of phoneoscopy.
Imaging the eye well allows us to educate others and ourselves, document pathology and to share the beautiful and the unusual. This site is dedicated to making this easier than ever to achieve.
Check out our practice face book pages where we try to share cases at:

Imaging the retina:Using the built in camera on a smart phone without modification it is possible to record high resolution fundic images, without the use of additional lenses or ophthalmoscopes.
This technique relies on the small size of the smart phone camera lens and the close proximity of the LED light to the optical axis. The use of a camera application (e.g. The iPhone Apps "procamera" or "Camera +" by Tap Tap) which allows continuous illumination of the field of view is key to allowing fundic illumination, fundic photography. Fundic videography can usually be performed using the native video app on most phones with the LED turned on during recording.
Imaging the lens: Using continuous near coaxial illumination, patience and a steady hand it is possible to use fundic reflections to retro-illuminate lens changes and document lens lesions in a way which is very difficult to achieve with conventional photographic techniques.
