Objective: To investigate the clinical features of ocular lesions in Behçet's disease in different countries. Methods: A descriptive questionnaire survey was performed. Results: 25 eye centres in 14 countries returned questionnaires on prevalent cases in 2006. Clinical data were analysed on 1,465 patients with ocular lesions. Recurrent oral aphthous ulcers were reported in 94.5%, skin lesions in 69.5% and genital ulcers in 61.4%. Most of the patients had bilateral and recurrent intraocular inflammation. Poor visual acuity was seen in 18.9% in women, but 24.8% in men (p<0.01). Panuveitis was seen more in men than in women (p<0.01). 23% of the patients had visual acuity equal to or worse than 20/200 at the final visit. The patients with poor vision were more frequently in India, Iran and Japan than in other countries (p<0.01). Conclusions: We report the largest contemporary international case series of patients with ocular involvement in Behçet's disease. Panuveitis was significantly more frequent in men than women, and men tended to have a worse visual prognosis. There were some differences in the clinical pattern of Behçet's disease in different countries. Despite modern treatment, the disease still carries a poor visual prognosis with one-quarter of the patients blind. [ABSTRACT FROM AUTHOR]

Background The importance of patient and public involvement (PPI) in healthcare decisions and research is increasingly recognised. This paper describes the aims, delivery, evaluation and impact of a 'Birdshot Day' organised for patients with birdshot uveitis, their carers and healthcare professionals. Methods Delivery of this event involved the close collaboration of patients with a large number of different healthcare professionals. The event's evaluation used established social research methods including qualitative questionnaires pre, post and 6 months following the event. The results were statistically analysed. Results Results indicated that this event significantly educated both patients and professionals. The sense of isolation felt by patients was reduced and networking was developed among all attendees. Patient priorities for research were recorded and invaluable insight into patients' needs for a better quality of life was gained. Conclusions The first undertaking of this novel PPI event achieved all its aims. It became even clearer that fundamental questions remain about birdshot uveitis, including aetiology, pathogenesis, practical clinical issues and impact on quality of life. These questions can only be addressed in partnership with patients. To this end, patients and professionals came together under the banner 'Team Birdshot' and the National Birdshot Research Network was launched. [ABSTRACT FROM AUTHOR]
