Dr harper austin retina7/23/2023 ![]() Continued use of teleretinal screening programs may show if this declining trend eventually stabilizes. This suggests sustained use of teleretinal screening and subsequent referral to ophthalmologists may reduce the number of unscreened diabetic patients and increase necessary referral of diabetic patients with DR in the population over time. There is a statistically significant decline in rates of detected diabetic retinopathy over four years of teleretinal screening. During this time, 65% of those requiring referral followed up with a retina specialist (Wong RW, et al. Clinics with 4-year data show majority of decrease in DR rate occurring from the first (22.34%) to third (16.93%) year of screening. There was a decline in DR rate from the first year of screening in 11 out of 12 clinics, displayed in Table 1. Statistically significant declines with p < 0.05 were also seen comparing the first to second year (20.63%, 1467/7112) and third year (20.18%, 1150/5700) and comparing second and third years to fourth year (Figure 1). Total consecutive yearly data was aggregated and rates of DR were compared from first to fourth year of screening using pairwise z-test for independent proportions with Holm adjustment of p-value for multiple comparisons.Īggregated yearly data comparison showed a statistically significant decline in DR rates from the first year of screening (22.56%, 1190/5275) to the fourth year (16.82%, 304/1807) with p < 0.00001. A retrospective analysis of DR rates captured by cameras across 12 Central Texas primary care clinics with 2-4 years of data obtained from Intelligent Retinal Imaging Systems (IRIS) cloud-based system was completed. ![]() We analyzed the trajectory of DR rates based on teleretinal images captured at primary care clinics in Central Texas over a 4-year period.ġ9,894 retinal image screenings of diabetic patients were reviewed by retina specialists to identify pathology. Year over year trending of diabetic retinopathy (DR) rates using teleretinal screening in the US remains minimally reported.
