The first report of the use of the smartphones for this purpose was in 2010 by Lord et al, 2 who showed that these devices could be used for many clinical and educational tools, including capturing images of the eye, such as external photos, slit-lamp photos, and fundus photos. 2 Since then, newer techniques and modifications have resulted in the acquisition of high-quality images that compare to images obtained with more expensive ophthalmic imaging devices.

You can take the picture, and it will appear on your PC.

My consultants at the time seemed indifferent to this suggestion but one of my seniors agreed with me. So when the camera was not in use (the vast majority of the time), we used it in the clinic. It helped me to develop my clinical skills and I found it particularly useful for learning how to examine the cornea and recognize a huge variety of pathologies.

One of the most crucial camera parameters to consider when deciding what iPhone version to use for slit lamp photography is its number of megapixels, even though more megapixels don’t necessarily translate into better pictures.

In addition, Maamari et al 14 described a prototype widefield lens attachment for the smartphone called Ocular CellScope, which can slide into the phone and capture widefield images using the phone’s built-in camera. Their technique could capture approximately 55º of the fundus in a single image ( Figure 8). Additional software could be used to stitch together the images to capture a larger overall image of the fundus. FUTURE APPLICATIONS
