Orbital compartment syndrome following tear trough filler injection.

A patient was treated with tear trough filler and developed a retrobulbar haemorrhage. This was managed acutely with a lateral canthotomy and cantholysis with no lasting visual compromise. This is the first reported case of an orbital compartment syndrome following filler injection and highlights the potential blinding complications which can occur. There should be an increased awareness of this complication amongst practitioners administering tear trough filler.
