According to a study at AAO2014, the 118th annual conference of the American Academy of Ophthalmology, smartphone technology can be used as an effective and portable tool for internal imaging of the eye. Researchers at the Rose Eye Institute at the State University of New York at Buffalo have successfully used an iPhone app as an inexpensive, portable and effective tool for imaging the inside of the eye. These subjects include diseases that are difficult to photograph with traditional methods. Suffering.
Photographic technology plays a vital role in documenting and tracking the development of ocular diseases. The most common type of ocular imaging is fundus photography. This requires a professional low-power microscope to be attached to a camera to take a picture, and the picture taken can be reviewed by another expert at another location or used for medical records. Standard equipment is targeted at adult patients and is typically located in a professional eye clinic. Therefore, these devices may not be used anywhere, and young people or patients who are in poor physical condition and unable to maintain an upright posture may not be able to use it. This will result in the loss of an opportunity to record significant changes in this patient population.
To solve this problem, the researchers used the iExaminer smartphone system and an iPhone to image 28 clinics and hospitalized pediatric patients who had different retinal and optic nerve conditions. The system includes panoramic ophthalmoscopes (an optical device that detects the inside of the eye) and an adapter that attaches the ophthalmoscope to the iPhone for photo taking and video capture. It images the key structures behind the eyes in a single picture without the need to expand the pupil's eye lotion. Related applications will assist in capturing, storing, and transferring data. This also enables remote medical consultation without violating patient privacy because it does not require disclosure of the patient's facial features.
“This system is useful not only for ophthalmologists, but also for physicians in the emergency department, doctors in hospitals, and general practitioners,†said chief researcher Jiaxi Ding. “Because I can continue to capture videos and photos behind the eyes through pupils without magnification, this potentially facilitates telemedicine consultation, which quickly achieves initial casualty classification without the need to wait for patient referrals.â€
However, the researchers also raised some of the challenges faced by this smartphone approach, such as the limited field of view of the patient's peripheral retina, the battery life of the ophthalmoscope when continuously imaging multiple patients, and the learning curve of the system. In addition, the current smartphone app settings have been approved by the US Food and Drug Administration, which is currently only compatible with the iPhone 4 and iPhone 4S, both of which have lower resolution than the latest iPhone cameras.
