What Is Lagophthalmos hero

What Is Lagophthalmos?

Lagophthalmos refers to the incomplete closure of the eyelids and can produce symptoms similar to dry eye syndrome, such as dry, itchy, watery eyes. In extreme cases, it can cause corneal ulcers.

There are several types of lagophthalmos, ranging from mild to severe. Common symptoms include:

  • Increased tearing
  • Dryness
  • Irritation
  • The sensation that something is stuck in the eye
  • Blurred vision
  • Eye pain, especially in the morning

A visit with Dr. James Evans can determine if lagophthalmos is causing or contributing to your dry eye symptoms.

Types of Lagophthalmos

When the eyelids don’t fully close during a blink, this is called “blink lagophthalmos.” Blinking keeps the eyes lubricated by spreading the tear film evenly along the eyes’ surface. An incomplete blink can lead to dry spots on the eye and other uncomfortable dry eye symptoms. Colliding eyelashes or tasks that require a high level of focus (such as working on a computer) can contribute to blink lagophthalmos.

Nocturnal Lagophthalmos

Nocturnal lagophthalmos occurs during sleep, so people with this condition may be unaware they have it. One common cause of this type of lagophthalmos is a decrease in fatty tissue behind the eyeball. Less cushioning causes the eye to sink further into the socket, making it more difficult for the lids to completely close. The fatty tissue can deteriorate for several reasons, including the presence of an autoimmune disease.

Paralytic Lagophthalmos

Paralytic lagophthalmos results from a paralyzed cranial nerve, thus preventing the eyelids from complete closure. Paralysis of the seventh cranial nerve can be caused by Bell’s palsy, tumors, or trauma.

Iatrogenic lagophthalmos

This is when the eyes can’t fully close due to medical treatment. Medical procedures that can cause lagophthalmos include Botox injections and sutures near the eye.

How Your Eye Doctor Can Help

There are several ways to treat lagophthalmos, and sometimes surgery may be necessary. It’s best to first visit Dr. James Evans to pinpoint the cause of your symptoms and try the least invasive and safest treatments before resorting to surgery. If left untreated, lagophthalmos can result in corneal damage.
