A Close-up Look at Handheld Retinal Imaging Devices vs. Ultrawide Field Images for Diabetic Retinopathy Severity

The study aimed to compare the severity of diabetic retinopathy (DR) identified using handheld retinal imaging and ultrawide field (UWF) images. The images of 225 eyes of 118 diabetic patients were compared based on the international classification for DR. The results showed that there was an exact agreement between UWF and handheld retinal imaging in 64.4% of eyes and 68% of persons and within the 1-step agreement in 90.7% of eyes and 92.9% of persons. The sensitivity and specificity for detecting DR using handheld imaging were high. However, when using PDR as a referral threshold, 37.0% of eyes or 30.8% of patients with PDR were missed, indicating that lower referral thresholds are needed when using handheld devices due to the identification of neovascular lesions outside of the handheld fields.
