The study was done to standardise the nomenclature for reporting OCT-A findings in the field of uveitis.

Members of the International Uveitis Study Group, of the American Uveitis Society and of the Sociedad Panamericana de Enfermedades Oculares responded to an online questionnaire about their preferred terminology when reporting on OCT-A findings.

108 uveitis specialists who participated in the survey were included in the analysis. 23 were considered OCT-A ‘experts’. There was an agreement in both groups for the definition of (WF)-OCT-A, and definition of neovascularization in uveitis. Moreover, there was a difference in the responses in other areas, such as quantification of ischaemia, definition of ‘large’ areas of ischaemia or terms to describe decreased OCT-A signal from different causes. There was an unanimous need of ‘users’ and ‘experts’ to distinguish size of decreased OCT-A signal in uveitis, to implement a quantitative measurement of decreased flow specifically for WF-OCT-A and to use different terms for different causes of decreased OCT-A signal.

The study concluded that there was considerable agreement in the terminology used by all uveitis experts, significant differences in terminology were noted between ‘users’ and ‘experts’. These differences indicate the need for standardisation of nomenclature among all uveitis specialists both for the purpose of reporting and in clinical use.
