Ophthalmic examinations of developmentally delayed/autistic children are challenging. Oral midazolam may be a viable alternative to general anaesthesia for this indication. Single-centre retrospective cohort study (January 2018-March 2020). Oral midazolam (0.5 mg/kg, max 15 mg). Metrics included: patient demographics, examination completion rate, duration of stay and adverse events. 50 oral midazolam examinations were performed (45 patients). Mean age was 79.12 months. All had developmental delay (66.67% autism). Time to ophthalmic examination was 60.31 minutes. Eye examination was successfully completed in 98%. No adverse events were reported. Mean stay was 3.35 hours. Oral midazolam (0.5 mg/kg, max 15 mg) is associated with safe, successful completion of ophthalmic examinations in children previously unexaminable in clinic.
