8. Preparation of the patient
This paragraph is dedicated to the patient preparation before taking pictures with the drsplus.
There are no specific restrictions based on the typology of patients that can be examined with drsplus.
drsplus is a non-mydriatic medical device, therefore it is not mandatory to dilate patients before taking
pictures.
It is recommended to give the patient the following instructions:
1) The acquisition of retinal images with drsplus does not involve any risk, in particular the device
will never touch the patient’s eye and the only effect perceived by the patient is a flash light
when the device acquires a picture;
2) Please find a comfortable position, keeping the forehead well placed on the device head-rest.;
3) Once a good position is found, please do not move and do not talk;
4) Open your eyes wide;
5) At the beginning of the exam, the device will move to find your eye. Such movement is normal:
when the device moves, please keep looking forward;
6) When a small green light appears, please look at such light and avoid blinking;
7) The acquisition of every picture will last less than 20 seconds.
After having given the instructions, place the patient in front of the device. Control the height of the
medical table or the height of the chair so that the patient is comfortable to place his forehead on the
head-rest of drsplus.
❖ Give the patient detailed information about the device operation before placing
the patient on the device.
❖ The minimum pupil diameter which ensures high quality of the images is 2.5 mm.
