Strabismus ~ Is treatment necessary?
Hello Doctor: My eyes are quite strange.
Most of the time they are normal, but whenever I do the following things: (1) when I am fatigued or tired, (2) when I read, look at the computer, or watch TV for too long, (3) when I zone out and think about things without concentrating on conversations, one of my eyes tends to drift outward involuntarily (strabismus), and (4) sometimes when I have been on the computer for too long and my eye wants to drift outward, I habitually and unconsciously close the drifting eye (because I feel that closing it reduces fatigue and prevents the eye from drifting).
I would like to ask: (1) My eyes were completely normal when I was younger; even when tired, they never exhibited abnormal drifting.
I only started noticing this strange symptom in my early thirties (I am 42 years old now).
Occasionally, when I have strabismus, I become immediately aware that someone is looking at my eyes, and I instinctively correct them (for aesthetic reasons, so I won’t be laughed at for having a wandering eye).
Therefore, I haven’t sought help from an ophthalmologist regarding the strabismus.
However, this symptom fluctuates; most of the time, my eyes are normal, but it tends to occur intermittently when I am tired, fatigued, or not focused.
Doctor, what could be causing these symptoms? (2) If these episodes become too frequent, how should I be examined and treated to restore normalcy? Thank you for your response, Doctor.

Hello Mr.
Wang: Your condition is intermittent exotropia.
There are two muscles responsible for the lateral movement of the eyeball: the lateral rectus muscle, which is responsible for outward movement, and the medial rectus muscle, which is responsible for inward movement.
In individuals with latent exotropia, the lateral rectus muscle is too strong, causing the eye to deviate outward.
Surgical correction can be performed by relaxing the lateral rectus muscle and strengthening the medial rectus muscle, which can restore proper alignment.

The ophthalmology department at Puzi Hospital in Taiwan is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Please note that online responses are for reference only; it is essential to seek medical attention at a healthcare facility if necessary.
I hope to have the opportunity to assist you.
Sincerely, Gao Pilin.

More Info
Intermittent strabismus, or the occasional misalignment of the eyes, can be a concerning issue, especially when it manifests during times of fatigue or distraction. Your description suggests that this condition has developed relatively recently in your life, which is not uncommon. Many adults experience changes in their vision or eye alignment as they age, particularly around the age of 30 and beyond.
1. Possible Causes: The intermittent nature of your strabismus could be attributed to several factors. One common cause is muscle fatigue. The muscles that control eye movement can become fatigued after prolonged periods of focusing on screens or reading, leading to temporary misalignment. Stress and fatigue can also exacerbate this condition, as they may affect your ability to maintain focus and control over your eye movements. Additionally, it could be related to a condition known as convergence insufficiency, where the eyes struggle to work together when looking at nearby objects, leading to one eye drifting outward.
2. When to Seek Treatment: If your symptoms are infrequent and do not significantly impact your daily life, it may not be necessary to seek immediate treatment. However, if you find that the episodes of strabismus are becoming more frequent, or if they are accompanied by other symptoms such as double vision, headaches, or significant discomfort, it would be wise to consult an eye care professional. They can perform a comprehensive eye examination to determine the underlying cause of your symptoms.
3. Diagnostic Evaluation: During your visit, the eye doctor may conduct a series of tests, including visual acuity tests, eye alignment assessments, and possibly imaging studies to evaluate the muscles and nerves controlling eye movement. They may also assess your ability to focus on near and far objects, which can help identify any convergence issues.
4. Treatment Options: Treatment for intermittent strabismus can vary based on the underlying cause. If muscle fatigue is the primary issue, the doctor may recommend strategies to reduce eye strain, such as taking regular breaks during prolonged screen time, practicing the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), and ensuring proper lighting while reading or working.
If the strabismus is more pronounced or persistent, options may include vision therapy, which involves exercises designed to improve coordination and control of the eye muscles. In some cases, corrective lenses or prisms may be prescribed to help align the eyes better. Surgery is typically considered a last resort for more severe cases that do not respond to other treatments.
5. Self-Care Strategies: In addition to professional treatment, there are self-care strategies you can implement. Ensure you maintain a proper ergonomic setup when using computers or reading, take regular breaks, and practice relaxation techniques to reduce overall stress.
In conclusion, while intermittent strabismus can be concerning, it is often manageable with the right approach. If your symptoms persist or worsen, seeking a thorough evaluation from an eye care professional is essential to determine the best course of action. Remember, early intervention can lead to better outcomes and help you maintain optimal eye health.
