Venous stasis orbitopathy: a clinical and echographic study

Area of Science:

• Ophthalmology
• Radiology
• Neurology

Background:

• Venous stasis orbitopathy (VSO) can stem from cavernous sinus and middle cranial fossa disorders.
• Differentiating vascular from non-vascular causes of VSO is crucial for appropriate management.
• Standardised echography is a valuable tool for evaluating orbital conditions.

Observation:

• This study examined 37 patients with echographic features of VSO.
• Patients were categorized into two groups: 17 with arteriovenous fistulae and 20 with non-vascular diseases.
• Detailed neuro-ophthalmic and ocular examinations were performed, including standardized A-scan and B-scan echography of the recti muscles.

Findings:

• Patients with arteriovenous fistulae exhibited significantly greater cumulative ocular recti muscle thickness (23.3 mm) compared to the non-fistula group (17.8 mm).
• Clinical findings such as the presence of a bruit and a uniocular rise in intraocular pressure were significantly more prevalent in the arteriovenous fistula group.
• Standardised echography successfully differentiated between arteriovenous fistulae and compressive mass lesions as causes of VSO.

Implications:

• Standardised echography is a safe, non-invasive method for diagnosing VSO.
• Echographic and clinical features can reliably distinguish between vascular (arteriovenous fistulae) and non-vascular causes of VSO.
• This differentiation aids in guiding treatment strategies for patients with VSO.
