Smart-TV Application for the Self Examination of the Distance Visual Acuity in Macular Edema Patients

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.

• DDiVAT Testing (Diagnostic test): 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.
• Distance visual acuity assessment via ETDRS chart (Diagnostic test): The distance visual acuity of each participant will be measured with the conventional method via ETDRS chart

Primary outcomes

• Distance visual acuity test via ETDRS chart [1 week]: The distance visual acuity of each participant will be evaluated by the same examiner
• Distance visual acuity self assessment via DDiVAT [1 week]: 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.
