The aim of this study is to validate the VISIODOL® scale for screening of pain in people with visual impairment.
The VISIODOL® monocentric study conducted at Clermont-Ferrand University Hospital is a cross-disciplinary diagnostic tool validation performed in patients with acquired or congenital visual impairment and healthy sighted volunteers. Different evaluations by thermal (Pathway Médoc®) and mechanical (electronic Von Frey®) tests will allow to compare the new VISIODOL® scale with the numerical scale, which is a commonly used tool. The ergonomic quality, the satisfaction of use and the quality of life, stress, anxiety and catastrophism of the patients will also be studied.

Evaluation of the ergonomic qualities of the scale
ergonomic survey : Different ergonomic parameters such as length, width and granulometry will be evaluated using a questionnaire.
Time frame: Day 0 + 1 hour
Evaluation of satisfaction of the use of the scale
satisfaction survey : The satisfaction of the participants in the study will be collected by means of a questionnaire.

Evaluation of anxiety
Hospital and Anxiety Depression Scale (HAD) : The Hospital Anxiety and Depression scale is a self-administered questionnaire in 14 items completed by the patient. It is used to determine the levels of anxiety and depression. Seven of the items relate to anxiety and seven relate to depression. Global score ranges from 0 to 42.
