    In this letter to the editor, Andrew Bastawrous, MRCOphth, describes how to capture good quality fundus images using a smartphone. This is a nice little how-to article. Less experienced ophthalmologists may find the technique useful for getting advice from senior colleagues, particularly in on-call situations. There is also potential for use in resource-poor settings.

    The author explains that a number of newer smartphones models have a 5-megapixel or greater forward-facing camera with a built-in flash and video capabilities. On video mode, the flash can be set to “on” so it is constantly illuminated and can act as a powerful coaxial light source for the ophthalmic camera lens. The ophthalmologist then holds the 20 D or 28 D lens as is normal when performing indirect ophthalmoscopy and holds the smartphone in the other hand. Once recording is complete, a still image can be captured from the video sequence and saved or shared as necessary.
