The Royal Victorian Eye and Ear Hospital Ocular Genetics Clinic (OGC) was established in 2018 to streamline IRD diagnosis in Victoria, Australia. This study audited the activities of the OGC during its first three years of operation, focusing on clinical and genetic diagnoses, and identifying areas for improvement in clinic workflow. The aim was to highlight how an integrated multidisciplinary care model – combining ophthalmology, clinical genetics, and genetic counselling – can address gaps in diagnostic access, care coordination and variant interpretation.</div></div><div><h3>Methods</h3><div>Retrospective chart review of suspected or confirmed IRD patients assessed in the OGC between December 2018 to December 2021.
