Globe Tethering (Globe Tenting) on Orbital CT

A focused, evidence-aligned overview for radiology and ophthalmology learners.

What is globe tethering?

Globe tethering (often described as globe tenting) refers to a conical, “tented” configuration of the posterior globe on CT caused by increased orbital tension and optic nerve stretching.

Why it matters on CT

• Supports the diagnosis of increased intraorbital pressure in acute/subacute settings.
• Posterior globe angle trends can correlate with proptosis severity and visual impairment.
• Marked tenting may indicate the need for urgent decompression.
