    Summary
    This summary is machine-generated.

    Dynamic proptosis, or exophthalmos with variable force, presents diverse causes in patients. This study identified neurofibromatosis, fistulas, and malignancies as common origins of this orbital condition.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Radiology

    Background:

    • Dynamic proptosis is characterized by exophthalmos that changes with applied force to orbital contents.
    • It can be spontaneous or induced, occurring with a normal or compromised bony orbit.

    Purpose of the Study:

    • To investigate the diverse etiologies of dynamic proptosis.
    • To analyze the clinical presentation and underlying causes in a cohort of patients.

    Main Methods:

    • Retrospective case series analysis of 26 patients diagnosed with dynamic proptosis.
    • Review of patient records to identify the specific causes and clinical characteristics.

    Main Results:

    • Neurofibromatosis was the most frequent cause (nine cases).

  • Other identified causes included fistulas (three cases), malignancies (three cases), meningoencephaloceles (two cases), mucoceles (two cases), surgery (two cases), orbital varix (two cases), dermoid cysts (two cases), and aneurysm (one case).

    • Conclusions:

    • Dynamic proptosis encompasses a wide spectrum of underlying conditions.
    • Accurate diagnosis of the cause is crucial for appropriate management of orbital abnormalities.
