Facial paralysis is a neuromuscular condition that can affect the mobility of the facial muscles, impacting functions such as blinking and eyelid closure. It can manifest as facial asymmetry, changes in muscle tone, pain, and functional deficits, notably difficulty in fully closing the eye on the affected side. This limitation can have a significant impact on the integrity of the ocular surface, increasing the risk of dryness, irritation, and corneal damage.<\/p>\n

Among the most frequent causes are trauma, infections, and neurological conditions. Regardless of the origin, one of the most significant functional complications is incomplete eyelid closure. When the eye does not close fully, it becomes more exposed to the environment, potentially leading to lesions on the ocular surface and vision changes, especially if there is no adequate protection.<\/p>\n

This article discusses the importance of eye protection in facial paralysis and the fundamental care needed to minimise complications, from a perspective that integrates specialised physiotherapy with ophthalmological surveillance.<\/p>\n

The anatomy of the eye and facial paralysis<\/h4>\n

Blinking and eye closure are essentially dependent on the orbicularis oculi muscle, innervated by the facial nerve. These movements are fundamental for the proper distribution of the tear film and for the mechanical protection of the ocular surface.<\/p>\n

When the facial nerve is compromised, the activation of this muscle is reduced or absent, leading to a diminished blink reflex and incomplete eyelid closure. As a consequence, the eye remains more exposed to the environment, compromising its natural lubrication.<\/p>\n

During sleep, the eye can remain partially open, which further increases the risk of irritation and eye injury, especially if there is no adequate protection.<\/p>\n

Problems associated with the absence of eye protection<\/h4>\n

The inability to adequately protect the eye in facial paralysis can lead to several complications, including:<\/p>\n
