P28 Implementation of non-mydriatic retinal photography and telemedicine strategy as tools for screening for diabetic retinopathy

Abstract

Background: During routine clinical visit to diabetologists, the availability of nonmydriatic retinography (this means without dilation of the patient´s pupil) could improve the rates of screening for diabetic retinopathy (DR). This method of screening, in addition to avoiding all the inconveniences associated with pupil dilation, allows the immediate analysis of the digital images and/or their sending for retinal specialist by telemedicine, resulting cost effective. Aims: To determine the frequency of DR with a non-mydriatic retinography coupled to asynchronous telemedicine and analyze risk factors associated with DR. Materials and methods: Cross sectional study, which included patients with diabetes who were ≥18 years old and assisted to routine clinical visit at medical center in Buenos Aires from August to December 2019. We excluded patients with type 1 or post transplantation diabetes less than 5 years from the onset of diabetes, or with ocular media opacities that hindered taking retinal photographs. The Ethics Review Committee approved this trial. All the participants singed the consent inform. All eyes fundus photographs were taken by diabetologists during medical appointment using a nonmydriatic 60-degree camera (Eidon®) and sent to single retinal specialist In patients with and without DR, we analyzed: glycated hemoglobin levels, the duration of diabetes, body mass index (BMI), hypertension and dyslipidemia frequencies. According data distribution, categorical and numeric variables are described in absolute frequency/percentage and median/RIQ, respectively. We conducted comparisons based on Fisher exact test and nonparametric tests.
