The Evolution of Visual Acuity Measured by Electronic Tablet / Computer of Exudative AMD Patients

A Prospective Study Comparing the Evolution of Visual Acuity Measured by Electronic Tablet or Computer and the Visual Acuity Measured by ETDRS in Patients Monitored and Treated for Exudative AMD

This pathology, DMLA, whose evolution is chronic, requires regular follow-up and care (IVTs) over a long period (several months or even years).

Increasing the number of patients to be followed and treated poses increasing problems for ophthalmologists to ensure regular follow-up of patients, followed by a need for satisfactory functional results.

Moreover, this regular follow-up imposes enormous constraints on patients and their families (some children or patients are still working).

Studies are beginning to emerge on the reliability of patient follow-up in telemedicine. The use of a measure of visual acuity by patients, Electronic Tablet (TE) or computer (O), and at home, seems a logical step to help us improve the quality of patient follow-up while spacing controls.

The aim of our study is thus to demonstrate that the measurement of the VA performed by TE or O is reliable. Indeed, during the follow-up of the patients, in the case where the patient's AV decreases, and whatever the reason

Our aim is to compare the evolution curves of the Visual Acuity (AV) measured in each patient on Electronic Tablet (TE)/ computer(O) and on the Early Treatment of Diabetic Retinopathy Study (ETDRS) scale, in order to check the reliability of the measurements performed by TE / O by comparing them with a well-known reference measure And is routinely practiced routinely in ophthalmology centers.

Measurement of visual acuity on TE / O will be carried out on an ETDRS AV scale, the size of the letters having been adapted to the reading distance (80 cm by 0.40 cm on the tablet). An ETDRS intermediate vision (EVI) or meadow vision (TEU) score according to the group will be established in the same way. The VA measurement will be supervised by a CRA trained to the extent of the VA, without the orthoptist or ophthalmologist being informed of the results obtained.
