PURPOSE: To screen visual acuity in two refugee camps in Greece and explore the feasibility of replicating these methods on a nationwide scale. METHODS: Visual acuity was assessed in all participants using web-based Democritus Digital Acuity & Reading Test (DDART). Furthermore, the immigrants responded to a structured questionnaire regarding their demographics and medical history. RESULTS: A total of 330 adult refugees and immigrants were recruited. A total of 47.3% of the patients had never undergone ophthalmological examination. A significant negative correlation was detected between age (r = -0.207, p < 0.001) and educational background (r = -0.135, p = 0.014), suggesting that younger immigrants who had attended compulsory education were more likely to have their eyes checked in their home country. A total of 6.97% of patients presented with impaired vision and were referred for further care. All remote DDART measurements presented no differences from the corresponding hospital-based data in the referred cases. CONCLUSIONS: Visual acuity screening using DDART provides valuable information regarding the visual capacity of refugees. The study outcomes suggest that pilot methods can be replicated on a nationwide scale. CLINICAL TRIALS: Gov number NCT05209581; date of registration: January 13, 2022.
