    Aims: To evaluate diabetic retinopathy MESHD retinopathy HP ( DR MESHD) screening with a portable handheld smartphone-based retinal camera and telemedicine in an urban primary health care setting; to evaluate the learning curve for image acquisition, performed by healthcare personnel without previous experience on retinal imaging. Methods: Prospective study that enrolled patients with type 2 diabetes mellitus MESHD diabetes mellitus HP ( T2DM MESHD) followed at a primary healthcare unit in São Paulo, Brazil. After a brief training in image acquisition, there was further continuous feedback during the remote image reading process. Each patient underwent two fundus and one anterior ocular segment images per eye, after mydriasis HP mydriasis MESHD. Patients were classified according need of referral. Results: A total of 627 adult TRANS individuals with T2DM MESHD underwent retinal evaluation. The population was composed by 63.2% female TRANS individuals, age TRANS median of 66 years-old, diabetes MESHD duration 10.7 ± 8.2 years and A1c 7.7 ± 1.9% (61 + 20.8 mmol/mol). The most prevalent associated comorbidities were arterial hypertension HP hypertension MESHD (80.3%) and dyslipidemia MESHD (50.2%). Referral decision was possible in 81.2% patients. Most patients had absent or non-referable DR MESHD; the main ocular media opacity detected was cataract HP cataract MESHD. After the 7th day of image acquisition, the daily rate of patients whose images allowed clinical decision was maintained above 80%. A higher A1c was associated with referable DR MESHD. Conclusion: A low-cost DR MESHD screening strategy with a handheld device and telemedicine is feasible and has the potential to increase coverage of DR MESHD screening in underserved areas; the possibility of mobile units is relevant for DR MESHD screening in the context of Covid-19 pandemic.
