ISCREEN-study: Online Nurse-assisted Eye-screening in Home Healthcare

Nurse-assisted eye-screening will take place with the Easee app, which is implemented on the tablet or laptop of the community nurse. The nurse's smartphone will function as a remote control by which he/she submits input to a computer screen that displays the test. If the participant can do the test by him or herself, the nurse will merely supervise to ensure correct application. Standard audio instructions guide the nurse and participant through the test. The test will start with triage questions, which are used to set up a correct referral. During the test, both eyes are tested consecutively, covering one eye at a time. The participant will wear his/her spectacles, if present. The participant is presented a sequence of optotypes (i.e. tumbling-E and triangle-circle optotypes) that the participant must correctly identify, in addition to various grate sizes, both near and at a distance. The Amsler grid test is performed to detect any macular problems.
