A ruptured globe occurs when rapid intraocular pressure elevation secondary to blunt trauma results in eyewall failure. [3] The rupture site may be at the point of impact but more commonly occurs at the weakest and thinnest areas of the sclera. [4] Regions prone to rupture are the rectus muscle insertion points, optic nerve insertion point ...
Canthotomy (also called lateral canthotomy and canthotomy with cantholysis) is a surgical procedure where the lateral canthus, or corner, of the eye is cut to relieve the fluid pressure inside or behind the eye, known as intraocular pressure (IOC). [1] The procedure is typically done in emergency situations when the intraocular pressure becomes ...

Blast-related ocular trauma. Blast-related ocular trauma comprises a specialized subgroup blast injuries which cause penetrating and blunt force injuries to the eye and its structure. The incidence of ocular trauma due to blast forces has increased dramatically with the introduction of new explosives technology into modern warfare.
