Newest Technology in Optometry

Ralph CotranTechnology has truly come a long way in all aspects of our lives, especially in the field of medicine. Researches are rolling out a new app kit called “Peek” which allows to physicians to test a patients’ eyesight in remote areas around the world. Optometrists can use a smartphone device to conduct the tests, which have been proven to be just as accurate as the traditional letter chart we are all so familiar with. 

The technology to make this device possible was put together by scientist at the London School of Hygiene & Tropical Medicine and researchers from the University of St Andrews. The app works in connection to a special device called the “Peek Retina” which allows for a thorough testing of the retina. Researched from JAMA Ophthalmology tested over 233 Kenyans in their homes, then distributed the patients to eye care centers around the world to be re-evaluated. Both tests showed similar results, meaning that scores derived from the Peek were just as reliable as the traditional visual acuity chart. 

So, what does this mean for the optometry community?

The new device can be used to detect early signs of poor vision, and as most of the world’s blind population resides in poor rural areas, this is a great opportunity to help millions around the world. Technology is becoming more and more accessible, and with the help of smart devices such as iPhones and tablets, bringing medical devices closer to those who are less fortunate has become much easier. 

Lead researcher and author of the study, Dr Andrew Bastawrous, was quoted that the ultimate goal of this apparatus is to use Peek Retina on people who need timely and appropriate treatment in order to diagnose their condition and hopefully see clearly again. The Peek Acuity test works by having the physician display a letter and positioning it in four different alignment, and then asking the patient to point the direction of the letter. Once the patient has answered, the doctor can easily move on to the next slide.

The only study conducted focused on Kenyan residents between over the age 55, however, this narrow test groups leaves some questions unanswered. Specialists believe that in order for Peek Acuity to take off, broader studies need to be conducted, inclusive of larger populations of different ages and backgrounds.
