    A novel injection timing switch precisely initiates fundus camera timers for angiography. This device enhances angiographic documentation by providing accurate injection timing, improving result evaluation and comparability.

    Area of Science:

    • Ophthalmology
    • Medical Imaging
    • Biomedical Engineering

    Background:

    • Accurate timing is crucial for evaluating angiographic results.
    • Current methods for timing angiography may lack precision.
    • Standardized quantitative data is needed for universal comparability of angiographic findings.

    Purpose of the Study:

    • To develop a simple and precise switch for initiating the timing unit of a fundus camera during angiography.
    • To enable accurate documentation of total elapsed injection time.
    • To enhance the evaluation and comparability of angiographic results.

    Main Methods:

    • Development of an injection/circulation-timing switch.
    • Mounting the switch on the syringe used for tracer material injection.
