Summary
This study screened visual acuity in refugees using the Democritus Digital Acuity & Reading Test (DDART). The findings indicate that this method is feasible for nationwide implementation, aiding in identifying vision impairments among refugee populations.
Area of Science:
- Ophthalmology
- Public Health
- Refugee Health
Background:
- Refugee populations often have limited access to regular healthcare, including eye examinations.
- Understanding the visual health status of refugees is crucial for their overall well-being and integration.
- Previous large-scale visual acuity screening in this demographic is limited.
Purpose of the Study:
- To conduct visual acuity screening in two refugee camps in Greece.
- To assess the feasibility of implementing these screening methods nationwide.
- To identify potential barriers and facilitators to eye care access in refugee populations.
Main Methods:
- Utilized the web-based Democritus Digital Acuity & Reading Test (DDART) for visual acuity assessment.
- Collected demographic and medical history data through structured questionnaires.
- Compared remote DDART measurements with hospital-based data for referred cases.
Main Results:
- Screened 330 adult refugees and immigrants; 47.3% had no prior ophthalmological examination.
- A significant negative correlation was found between age and education level with prior eye checks.
- Identified 6.97% of patients with impaired vision who were referred for further care.
- Remote DDART measurements showed no significant difference from hospital-based data.
Conclusions:
- Web-based DDART screening effectively provides valuable data on refugee visual capacity.
- The pilot study demonstrates the feasibility of nationwide replication of these screening methods.
- This approach can improve access to eye care and early detection of vision problems in displaced populations.
