Lagophthalmos, as described in the reference material from Eyewiki, is the inability to completely close the eyelids. This condition leaves part of the eye exposed, making it vulnerable to damage, especially during blinking and sleep.
Understanding Lagophthalmos
Here's a breakdown of what lagophthalmos entails:
- Definition: The inability to fully close the eyelids.
- Consequences: Exposure of the eye leading to potential damage. This is because a portion of the eye remains open, even during blinking and sleep.
Causes of Lagophthalmos
The reference categorizes the causes as follows:
- Facial Nerve Dysfunction (Paralytic Lagophthalmos): This is one specific type of lagophthalmos resulting from issues with the facial nerve.
In summary, Lagophthalmos involves incomplete eyelid closure leading to potential eye damage due to exposure. The etiology is varied but can include facial nerve dysfunction.
