Orbital venous anomalies, previously termed lymphangiomas or orbital varices, are common in infants and children. These vascular malformations often require conservative management due to surgical challenges.

Area of Science:

  • Ophthalmology
  • Vascular Malformations
  • Pediatric Surgery

Background:

  • Lesions in the orbit, previously classified as lymphangiomas or orbital varices, present diagnostic and therapeutic challenges.
  • Understanding the natural history and optimal management of these orbital lesions is crucial for patient care.

Purpose of the Study:

  • To establish the natural history of orbital vascular lesions.
  • To determine the probable nature and optimal treatment strategies for these lesions.

Main Methods:

  • Retrospective review of clinical and radiologic records for 158 patients.
  • Surgical intervention in 91 patients with re-examination of 57 histologic specimens.

Main Results:

  • Lesions typically present as dark blue swellings in infants and children, often associated with hemorrhage or proptosis.

  • Computed tomography revealed smooth, dense lesions; half enlarged with the Valsalva maneuver, and 31% contained phleboliths.
  • Surgical excision, primarily for cosmetic reasons, revealed endothelium-lined channels containing blood and clear fluid.

    • Conclusions:

    • Clinical behavior and prevalence suggest a hamartoma, with findings supporting a venous origin for these orbital lesions.
    • The term "orbital venous anomaly" accurately describes these lesions, which often connect with or replace orbital veins.
    • Conservative management is recommended due to surgical difficulties, despite the need for excision in cases of bleeding or enlargement.
