![]() A patient simply needs to look at the device one eye at a time. Unlike conventional dilated eye exams, high-resolution retinal imaging doesn’t require the use of dilated eye drops or any contact with your eyes for that matter. If you need to go home right after an eye exam or don’t want to experience the discomfort stemming from dilated pupils, you can ask your optician to use a high-resolution optical imaging instead of a dilated eye exam. As such, we recommend waiting for a few hours for the effects to wear off before you drive back home. During this time, your pupils will be more sensitive to light. The eye drops usually take about 15 to 30 minutes to take effect and 4 to 6 hours to wear off. ![]() What are the benefits of high-resolution retinal imaging? And why do opticians recommend patients undergo high-resolution retinal imaging in addition to traditional retinal exams? The Advantages of Optical High-Resolution Retinal ImagingĬonvenience – It’s hard for eye doctors to examine your eyes if the pupils aren’t dilated or widened, which is why they’ll give you eye drops to dilate your pupils during a routine eye exam. While traditional inspection methods have a high degree of accuracy, your optician may recommend high-resolution retinal imaging in addition to the traditional retinal exam if you’re at high risk of developing diabetes, macular degeneration, glaucoma, and other retinal conditions. Keep in mind that the effectiveness of routine eye exams depends on their accuracy, which in turn depends on the kinds of technology used. However, if they have known risk factors or are nearing the age of 60, they should see their optician more frequently. īy Andrei Ionescu, Staff WriterĬheck us out on EarthSnap, a free app brought to you by Eric Ralls and a rule of thumb, patients with no known risk factors for retinal diseases undergo a comprehensive eye examination every two years. The study is published in the journal eLife. The fact that we might be able to track their efficacy in such a low cost, non-invasive way is a huge plus,” Kapahi concluded. This is human data that provides targets for potential treatments for age-related diseases. ![]() “It would be really informative to understand how these genes, which are already linked to other age-related diseases, are affecting the changes we are seeing in the eye. In addition, the scientists performed a genome-wide association study (GWAS) to establish the genetic basis for an aging clock relying on retinal scans, which they call eyeAge, and discovered several key genes that contribute to aging and age-related diseases. Through the EyePACS longitudinal dataset involving multiple scans from individual people over time, our results show a more accurate positive prediction ratio for two consecutive visits of individual rather than random, time-matched individuals,” explained lead author Sara Ahadi, a senior computational biologist at Alkahest, a biopharmaceutical company focusing on age-related diseases. “Our study emphasizes the value of longitudinal data for analyzing accurate aging trajectories. However, since subtle changes in the retina’s small blood vessels can often go undetected even by the most sophisticated instruments, the experts collaborated with Google Research to train a deep learning computer model using the EyePACS data set that involves over 10,000 patients and applying it to patients from the UK Biobank. Moreover, previous studies have shown that changes in the eye accompany aging and age-related diseases, such as age-related macular degeneration (AMD), diabetic retinopathy, Parkinson’s or Alzheimer’s, as well as other health conditions, including early signs of AIDS, chronic high blood pressure, or developing eye tumors. According to the researchers, since changes in the eyes are less susceptible to daily fluctuations than biomarkers in the blood that could be easily influenced by diet or current infections, retinal scans are more reliable as indicators of aging.
