What sign might indicate an orbital fracture following a blunt trauma?

Enophthalmos, which is the retraction or sinking of the eyeball into the orbit, can indeed be a sign of an orbital fracture. This condition occurs when there is a loss of structural support around the eye, often as a result of a fracture in the orbital floor or walls, leading to a change in the positioning of the eyeball.

In the case of blunt trauma to the eye or surrounding structures, fractures can result in a space that allows the eye to be displaced inward. As the bone structure supporting the eye is compromised, it results in this noticeable retraction of the eye, which can be observed upon clinical examination.

While conjunctival injection, periorbital edema, and raccoon eyes may also present as signs associated with trauma to the eye, they do not specifically indicate an orbital fracture with the same certainty as enophthalmos. Conjunctival injection involves redness of the conjunctiva and may occur due to various causes, including irritation or injury but is not definitive for fracture. Periorbital edema is the swelling around the eyes, which can result from trauma but is not specific to orbital fractures. Raccoon eyes, or periorbital ecchymosis, indicate bruising around the eyes due
