Abstrakt: Background: Type 1 Usher syndrome (USH1) is a rare disease and major cause of genetic deaf-blindness. Deafness is present from birth while retinitis pigmentosa (RP) which typically presents during childhood is progressive leading to blindness. The aim of this research was to develop a disease model describing USH1 symptoms and their impact on patients' lives.
Materials and Methods: Qualitative interviews were conducted with patients (pediatric and adult) and parents of children and adolescents with USH1. Interviewed subjects were enrolled through ophthalmologists from specialized eye centers in the USA and in France. Trained interviewers used semi-structured techniques to elicit concepts relevant to patients and their parents. Thematic analysis of interview transcripts led to the identification of concepts which were organized to generate a disease model.
Results: A total of 18 patients (7 in the US; 11 in France)- 9 adults, 4 adolescents, and 5 children- and 9 mothers were interviewed. The most cited ocular symptoms were difficulty seeing at night and loss of peripheral vision. Interviewees reported limitations on Physical (e.g. difficulty moving), Mental (e.g. fear about falling), Social (e.g. difficulty discussing disease with others) and Role (e.g. difficulties at school/work) functioning. These impacts were, when possible, mitigated by coping strategies and support (e.g. using electronic devices, having a positive/proactive attitude).
Conclusions: This research provides an overview of symptoms experienced by patients with USH1 and highlights the dramatic impact these have on patients' lives, allowing the identification of concepts of importance when evaluating therapeutic treatments in development for RP.
