Which sign is considered the earliest eye sign in cases of strangulation?

The earliest eye sign observed in cases of strangulation is bulging eyes, which is primarily due to the increased venous pressure and decreased venous return from the head caused by constriction of the neck. This can lead to engorgement of the vessels around the eyes and result in proptosis, or bulging of the eyes.

In the context of strangulation, this sign may develop quickly as the constriction affects blood flow and pressure in the ocular and surrounding tissues. It is crucial to recognize this sign in forensic examinations, as it can provide critical evidence regarding the nature and circumstances of the strangulation.

Other signs, such as lividity and corneal clouding, occur later in the process of death or after prolonged strangulation, while fresh corneal injury is associated with trauma rather than the direct effects of strangulation itself. Thus, bulging eyes serve as an important early indicator in forensic assessments of strangulation cases.
