Welch Allyn iExaminer: An app that lets you use your iPhone for eye checkups

Researchers have successfully used iPhone app Welch Allyn iExaminer for imaging the inside of the eye of immobile and paediatric patients.

The team used the iExaminer smartphone system and an iPhone to image 28 paediatric patients with a diverse range of retinal and optic nerve conditions.

The system consists of a PanOptic Ophthalmoscope (a lighted instrument to examine the inside of the eye) and an adapter that attaches the ophthalmoscope to an iPhone to enable taking photos and videos.

It can image key structures of the back of the eye in a single view without necessarily requiring dilation drops. The associated app facilitates capture, storage and transfer of data. This also makes it possible for real-time tele-medicine consultation without violating patient identity as no external facial features are revealed.

"This system could be useful not only to ophthalmologists but also physicians, hospitals and general practitioners," said lead researcher Jiaxi Ding from the Ross Eye Institute at University at Buffalo in the US.

Because it can instantly capture photos and videos of the back of the eye through an undilated pupil, "there is potential for prompt tele-medicine consultations with an ophthalmologist and getting preliminary triage answers to the patient more quickly than waiting for standard office referral," he added.

Photography plays a critical role in documenting and tracking the progression of eye diseases.

The results were shared at "AAO 2014" - the 118th annual meeting of the American Academy of Ophthalmology.
