Duane syndrome (DS) is a rare eye disorder that some people are born with. It occurs when the muscles and nerves around the eye don't work together properly, which limits the eye's ability to move as it should. Duane syndrome is also known as Duane's syndrome, Duane retraction syndrome, or Stilling-Turk syndrome.
Duane syndrome is caused by abnormal development of the nerves that control the eye muscles during pregnancy. In some cases, these nerves may be missing entirely. As a result, certain eye muscles may stretch when they should tighten or remain loose when they should contract. While the exact cause of Duane syndrome is unknown, experts believe that a combination of genetic and environmental factors may play a role.
The most common symptoms of Duane syndrome include:
Strabismus (misaligned eyes)
Narrowing of one eyelid
Reduced vision in the affected eye (amblyopia or "lazy eye")
Upward or downward shooting of the affected eye
Abnormal head position (tilting or turning to keep eyes straight)
Some people with Duane syndrome may also experience double vision, headaches, and neck pain due to their abnormal head position.
There are three types of Duane syndrome:
Type 1: The affected eye cannot move outward toward the ear (most common)
Type 2: The affected eye cannot move inward toward the nose
Type 3: The eye cannot move outward or inward
Duane syndrome is usually diagnosed before the age of 10 due to its distinct symptoms. An eye doctor will perform a comprehensive eye exam, which may include a vision test, measurements of eye movement, and an examination of the eye itself. In some cases, additional tests such as hearing exams, spine evaluations, or genetic testing may be recommended.
While there is no cure for Duane syndrome, several treatment options can help manage the condition and protect vision:
Prescription glasses or contact lenses to improve vision
Eye patching to treat amblyopia (lazy eye)
Special lenses that shift vision to promote a more natural head position
Regular eye exams to monitor the condition and address any changes
In severe cases, eye muscle surgery to help compensate for affected muscles
It is essential for people with Duane syndrome to work closely with their eye doctor to develop an individualized treatment plan that addresses their specific needs. With proper management and regular check-ups, most people with Duane syndrome can maintain good vision and minimize the impact of the condition on their daily lives.
