Road Testing D-EYE In A Clinical Setting

Edited from: ASCRS Retina Times Journal Issue #69 Volume 35, Number 3 – Summer 2017

“Retina Times Road Test Editor asked 3 ASCRS Colleagues from the US to evaluate and report on the image quality, ease of use, and utility and to offer an opinion on how these products may be of use to retina specialists and other medical specialists.”

 Summary Comments from the Road Testers:

Jorge A. Fortun, MD

Bascom Palmer Eye Institute

University of Miami Miller School of medicine

Miami, Florida

“Overall, the D-EYE is a well-executed system for what I consider to be its designed functionality: to serve as a portable, readily accessible, and relatively inexpensive digital direct ophthalmoscope that enables image capture and sharing.”

 “The D-EYE’s utility as a telemedicine tool for non-ophthalmologists to evaluate patients and adequately direct further ophthalmologic care by sharing findings with ophthalmology colleagues is readily evident.”


Amy C. Schefler, MD

Retina Consultants of Houston

Houston, Texas

The good news about the D-EYE is that the quality of the images is excellent in both dilated and, to a lesser extent, undilated pupils”.

“The camera does well at imaging the wide spectrum of eyes of varying pigmentation, as well as pathology that does not have much intrinsic contrast.”

 “Overall, the D-EYE would be most useful as a screening tool for glaucoma suspects in a mobile clinic or primary care doctor’s office. I don’t think it will have a critical role in a retina setting, but could be useful for a very quick glimpse of the macula in a mobile, rural, or developing-country setting.”


Yoshihiro Yonekawa, MD

Massachusetts Eye and Ear Infirmary

Boston Children’s Hospital

“For the price of 1 New England winter heating bill, the D-EYE can now transform a physician’s smartphone into an ultra-portable fundus camera.”

 “Dilated examinations are easily performed in clinic, but photo documentation may not be readily available, and the D-EYE makes it possible—whether it’s for following disc cupping or posterior nevi, or for tele-consultations.”

“…. primary care providers, hospitalists, neurologists, and emergency room providers will most appreciate the new technology. D-EYE is likely to be an easier and more accurate examination than the direct ophthalmoscope for non-ophthalmologists”

“Plus, these images can be documented and forwarded to ophthalmologists for remote consultations. It’s conceivable that glaucoma tele-screenings may benefit from this economical option.”

“It’s conceivable that patients may be able to send in images of their optic discs to their ophthalmologists who are overwhelmed by the increasing number of glaucoma patients.”


D-EYE – How does it work?

The lens design attaches to the smartphone utilizing the LED light source turning the smartphone into a digital ophthalmoscope. The patent pending lens design incorporates a beam splitter that redirects the light eliminating all corneal glare. Aiming at arm’s length, the ease of finding the optic disc while eliminating that uncomfortable “up-close” feeling when using a traditional ophthalmoscope plays a major role in getting great results during the exam.

The D-EYE “ImageSelect  based application creates the ability for the examiner to take a lengthy examination of the retina with the possibility to discover serious retinal pathologies that can often be missed.

With the lens properly aligned and 1 cm from the pupil, the acquisition protocol followed is to pan the retina, starting from the posterior pole and then moving to the upper, nasal, inferior, and nasal peripheral retina to the equator. Color high definition videos of the retina encompassing the posterior pole, including the macula, optic disc, and peripheral retina are obtained and can be converted to single images after the video is completed.

 Upon completion, ImageSelect™ creates the ability for the examiner to select specific frames from 30 second recorded videos and save as individual images to the patient record bringing tremendous improvement to a serious patient examination protocol.

 The ImageSelect set-up feature allows the user to pre-set and post edit photo settings to adjust or enhance images based on what the examiner is seeing in each photo. Customizable settings can be chosen based on the color and pigmentation of the patients’ eye delivering clear and sharp final exam images of the patient’s retina.

 Another essential feature included with ImageSelect™ is the easy “share and save” process of patient exams that can be stored externally from the smartphone and shared with other medical specialists for further patient assessment. The “share and save “process includes:

 A LAN share feature has been developed that moves the on board application based HIPAA compliant patient file to a local network for Windows PCs and Macs. This type of operation allows users to share data with Patient Information (PHI). A (confidential) PDF report including specific medical information and the exam results can be generated from the application.

 Images and videos with no patient information can be sent via email, instant messaging, social media and Apple AirDrop™ so multiple colleagues can assist with further assessment of the exam.

 ImageSelect™ brings the important ophthalmoscopy protocol back to the forefront of an initial patient physical exam.

 Several clinical studies have been published. D-EYE is currently being used by Ophthalmologists, Optometrists, Neurologists, Pediatricians, Endocrinologists, Hospitalists, Primary Care and Emergency Medical Physicians, Nurse Practitioners to name a few of many specialists who have discovered how easy it is to perform ophthalmoscopy obtaining great results in just a few minutes.

D-EYE and the D-EYE 2.0 Application can be used with the iPhone 5, 5S, SE, 6, 6S, 6+, 6S+ iPhone 7. Shop now.
