Orbital Varices: A Summary of a Rare but Clinically Significant Entity

Orbital varices are characterized by thin-walled, distensible venous channels that communicate with the normal orbital venous system. These rare venous malformations account for approximately 1.3% of all orbital masses. Varices can be classified as primary or secondary; primary varices are congenital, while secondary orbital varices are acquired, often resulting from arteriovenous malformations or arteriovenous fistulas. Due to their rarity, orbital varices present diagnostic and management challenges. However, timely identification is crucial, as they can lead to significant complications, including thrombosis and haemorrhage.
