Most non-traumatic orbital hemorrhages stem from vascular anomalies. Imaging aids diagnosis, and most bleeds resolve spontaneously, rarely requiring surgery for optic nerve issues.

Area of Science:

  • Ophthalmology
  • Vascular Surgery
  • Radiology

Background:

  • Non-traumatic orbital hemorrhage is a clinical presentation requiring thorough investigation.
  • Understanding the etiology and natural history is crucial for appropriate patient management.

Purpose of the Study:

  • To determine the incidence of orbital vascular anomalies in non-traumatic orbital hemorrhage.
  • To identify systemic associations and predisposing factors.
  • To describe the natural history and optimal management strategies.

Main Methods:

  • Retrospective review of 115 patients with non-traumatic orbital hemorrhage.
  • Analysis of clinical findings, investigations, management, and patient outcomes.
  • Utilized computed tomography and magnetic resonance imaging for orbital assessment.

Main Results:

  • Orbital vascular malformations were identified in 90% of patients.
  • Predisposing factors like childbirth or hypertension were present in 11%.
  • Acute painful proptosis was the most common presentation; 32% had reduced visual acuity at presentation. Spontaneous resolution occurred in 89% of cases.

Conclusions:

  • The majority of orbital hemorrhages are linked to vascular anomalies.
  • Systemic causes should be investigated when anomalies are absent.
  • Most bleeds are venous, self-limiting, and rarely require surgical intervention, primarily for optic nerve compromise.
