Purpose: To compare the effectiveness of tele-screening using a novel enhanced retinal thickness analyzer (RTA) with onsite routine ophthalmologic examination for diabetic retinopathy.
Method: A consecutive series of 31 eyes from diabetic patients were included. All underwent ophthalmologic examination including stereoscopic dilated funduscopy and scanning with the RTA. The RTA reports consisted of a wide-angle, red-free fundus photograph and a macular-region retinal thickness map. Reports were graded by three independent graders in a masked manner. The diagnoses of proliferative retinopathy, macular edema, and treatment decisions made by the RTA graders and the clinical examiner were compared.
Results: On clinical examination 5 of 31 eyes were diagnosed with proliferative diabetic retinopathy (PDR). All 5 were referred for treatment by two graders and 4 eyes by one grader. All eyes with PDR and 12 of the 26 eyes with non-proliferative diabetic retinopathy showed severe macular edema. Seven of the 12 eyes with macular edema were clinically eligible for focal laser treatment, all of them were detected by all RTA graders. Macular thickening was detected in 8 eyes by RTA where no treatment was necessary judged by clinical examination. Thus sensitivity was mean 93% for detecting PDR and 100% for detecting
