Summary
Nontraumatic subperiosteal orbital hemorrhage (NTSOH) typically occurs in females due to increased venous pressure and is usually located superiorly. Most cases resolve without surgery, but visual loss can occur in rare instances.
Area of Science:
- Ophthalmology
- Radiology
- Vascular Surgery
Background:
- Nontraumatic subperiosteal orbital hemorrhage (NTSOH) is a rare condition.
- It is often associated with increased cranial venous pressure, bleeding disorders, or sinusitis.
Observation:
- This study analyzed nine cases of NTSOH and reviewed existing literature.
- Patients ranged from birth to 73 years old, and all were female.
- Lesions were predominantly superiorly located and linked to sudden increases in venous pressure.
Findings:
- Most NTSOH cases did not require surgical intervention.
- The bilateral case, associated with disseminated intravascular coagulation, was the only instance of visual loss, possibly due to ischemic optic neuropathy.
- Computed tomography (CT) scans were utilized for diagnosis.
Implications:
- NTSOH can affect any age group, commonly linked to elevated venous pressure.
- Characteristic clinical and radiologic findings support conservative management when visual function is preserved.
- Prompt diagnosis and management are crucial, especially in cases with visual compromise.
