What is a significant concern with exophthalmos?

Exophthalmos, which refers to an abnormal protrusion of the eyeball, is associated with several potential complications related to the eye and its function. The correct choice indicates that one significant concern with exophthalmos is the alteration in moisture of the eye.

In cases of exophthalmos, the eyelids may struggle to fully cover the eye, leading to exposure and insufficient moisture. This can result in dry eye syndrome, increasing the risk of irritation, redness, and potentially leading to more severe conditions such as corneal damage or infections due to the constant exposure of the ocular surface.

Addressing the moisture level of the eye is crucial because inadequate lubrication can affect overall eye health and comfort, making it a primary concern in patients with exophthalmos. Other options, while relevant to ocular health, do not capture the immediate and critical implications of moisture imbalance resulting from improper eyelid closure.
