    Area of Science:

    • Ophthalmology
    • Medical Devices
    • Anatomy

    Background:

    • The lacrimal excretory passages, including the lacrimal sac and nasolacrimal duct, are crucial for tear drainage.
    • Standard examination procedures for the lacrimal outflow system can be limited in their ability to provide direct visualization.
    • Accurate diagnosis of conditions affecting these structures is essential for effective treatment.

    Purpose of the Study:

    • To describe a novel miniature caliber endoscope designed for the lacrimal excretory passages.
    • To highlight the diagnostic capabilities of this endoscope for inspecting the lacrimal sac and nasolacrimal duct.

    Main Methods:

    • Development and description of a miniature caliber endoscope.
    • Introduction of the endoscope into the lacrimal excretory passages.

    Related Experiment Videos

  • Direct observation and diagnostic inspection of the lacrimal sac and nasolacrimal duct lining and contents.

    • Main Results:

    • The miniature endoscope enables direct visualization of the internal structures of the lacrimal sac and nasolacrimal duct.
    • The instrument facilitates detailed inspection of the contents and lining of these passages.
    • The endoscope serves as a complementary tool to existing diagnostic methods.

    Conclusions:

    • The described miniature endoscope is a valuable tool for the direct examination of the lacrimal excretory passages.
    • This technology enhances diagnostic capabilities for conditions affecting the lacrimal sac and nasolacrimal duct.
    • It offers a complementary approach to standard examination procedures for the lacrimal outflow system.
