The progressive nature of aniridia is frequently accompanied by secondary ocular complications such as glaucoma and aniridia-associated keratopathy, which can lead to severely impaired vision or blindness. The genetic basis of aniridia has been the subject of numerous studies, leading to the development of innovative therapeutic options based on PAX6 nonsense mutations.

The majority of studies evaluate the quality of life using quantitative measures and standardised scales that offer relevant information about experience with the disease in multiple aspects. The main objective of the research was to examine in depth the quality of life and unmet needs of patients diagnosed with FD in relation to their disease and treatment. A qualitative and transversal study was carried out in two stages: (a) nine semi-structured qualitative interviews with patients and one representative of the patient association, conducted individually by phone; (b) a focus group was set up with three patients diagnosed with FD and one relative.

Diagnosis has a significant impact on both those suffering from the disease and on the family environment. The symptoms and evolution of the disease are highly variable among the patients interviewed and depend on the years diagnosed as well as the time taken to receive the diagnosis. The families of the interviewees have to go through an adjustment process in light of the significant psychological impact brought about by the disease. Patients show various unmet needs. The need mentioned most is to have more information, support, and understanding from people around them and society, improving empathy and raising awareness about the difficulties faced by people with FD while giving the disease visibility.
