Brief summary

Primary objective of our study is the development and validation of an application for smart-TVs for the self-examination of the distant visual acuity of patients diagnosed with macular edema.

Detailed description

Present study aims to develop and validate an application installed in Smart-TVs. This application will be referred to patients suffering from macular edema, allowing the self-examination of the patient in terms of distant visual acuity. The development of a simple but reliable way of self-examination of distant visual acuity would bring beneficial results in the overall management of these patients as significantly would reduce the flows to the outpatient ophthalmology clinics of the NSS Hospitals, would serve the purposes of the social distancing imposed by the current state of the pandemic but also any analogous situation and would help the patient to be vigilant and actively involved in the management of his disease.

Interventions

DIAGNOSTIC_TESTDDiVAT Testing

Participants will self examine his/her distance visual acuity via application in a simulation room of our department with certain predetermined environmental lighting conditions using the same smart devices.

DIAGNOSTIC_TESTDistance visual acuity assessment via ETDRS chart

The distance visual acuity of each participant will be measured with the conventional method via ETDRS chart
