To start a VA session the ECP must access the system via their aos-hub.com account. In this stage the ECP and patient are not yet connected via the video call. The ECP must set up the call and invite the patient, then the patient goes through a setup process before the video call connects.

If you do not have access to the VA system you will need to contact your AOS account manager or support@aos-hub.com for more information.

Starting a VA session:

  1. Log in to the AOS hub

  2. Select the patient

  3. On the patient summary page, select the ‘Visual Acuity Exam’ button (figure 1)
