Eyelash Symptom

The eyelash symptom is characterized by the absence of immersion of the eyelashes into the skin fold of the eyelid when the eye is closed. This is a sign of facial nerve paresis caused by weakness of the orbicularis oculi muscle.

With normal functioning of the facial nerve and the orbicularis oculi muscle, the eyelashes completely descend into the skin fold of the upper eyelid when a person closes his eyes. However, if the facial nerve is damaged and the orbicularis oculi muscle is weakened, this does not happen. The eyelashes only partially fall when you close your eyes or even remain in the same position without touching the skin of the eyelid.

Thus, the inability of the eyelashes to fully sink into the fold of the upper eyelid when closing the eyes indicates paresis of the facial muscles and is a pathognomonic symptom of damage to the facial nerve. The presence of the Eyelash symptom requires examination by a neurologist to identify the cause and extent of damage to the facial nerve.

The eyelash sign is an important diagnostic sign for identifying facial paralysis. This symptom manifests itself in the absence of immersion of eyelashes into the skin of the eyelid when closing the eyes. It is often discovered during the examination and treatment of patients with facial disorders, such as facial paralysis due to injury or tumor.

How does this symptom work? While the facial nerve carries signals to regulate the muscles of the face, it also supplies the muscles of the eyelids, which are responsible for closing and opening the pupils. For normal facial nerve function, the eyelid muscles should close along with the other facial muscles when using the outer facial muscles. If the facial nerve is damaged, then the eye muscles cannot function normally, which leads to the lack of immersion of the eyelashes into the fold of the skin of the eyelid when the eye is pinched. This disorder is the result of inadequate action of the facial nerve on the muscles of the eyelids and may indicate the presence of paralysis.

The use of this symptom in clinical practice helps to quickly and accurately determine the patient's condition. However, it should be borne in mind that symptoms can be caused not only by damage to the facial nerve or paralysis, but also by other diseases that cause paresis of the facial muscles. Therefore, based on only one symptom it is impossible to make
