When looking far with the left eye, it tends to drift to the left?

Hello, doctor.
Recently, I recorded a video on my phone and noticed that my left eye tends to drift outward slightly when I look at distant objects, while it appears normal when looking at nearby objects.
I have a slight difference in eye size and height, and I'm unsure if this has any impact.
I asked my family to check if I have strabismus, but they didn't seem to notice anything.
Over the past few days, I've been paying attention and found that when I suddenly look at something far away, it takes me a second to focus clearly.
I'm not sure if this is considered normal.
I do not have myopia.
I would like to ask you, doctor, is this strabismus? Can it be corrected through eye exercises? (I'm really afraid I might need surgery.) Can a regular ophthalmology clinic perform the necessary examinations, or do I need to go to a larger hospital for evaluation? Thank you, doctor.
🙏

Hello: Based on the symptoms you described, it is possible that you have strabismus.
Strabismus refers to the misalignment of the visual axes of the two eyes, resulting in an inability to focus on the same target simultaneously.
There are many types of strabismus, including esotropia, exotropia, hypertropia, and hypotropia.
Your condition may be intermittent exotropia, which is characterized by one eye drifting outward when looking at distant objects.
Common causes of intermittent exotropia include: * Extraocular muscle paralysis or weakness * Refractive errors (such as hyperopia, myopia, or astigmatism) * Congenital factors * Head trauma Intermittent exotropia may lead to the following symptoms: * Blurred vision * Double vision * Headaches * Fatigue If diagnosed with strabismus, treatment options include: * Correcting refractive errors: If strabismus is caused by refractive errors, wearing glasses or contact lenses can improve symptoms.
* Eye exercises: Eye exercises can help improve the strength and coordination of the extraocular muscles.
* Surgery: If other treatment methods are ineffective, surgery may be performed to adjust the extraocular muscles to correct strabismus.
It is recommended that you visit an ophthalmology clinic or a major hospital for an examination, where an ophthalmologist can develop a treatment plan based on your specific situation.

Hello,
Thank you for reaching out with your concerns regarding your eye health. Based on your description, it sounds like you are experiencing some visual discrepancies, particularly with your left eye appearing to drift outward when focusing on distant objects. This can indeed be concerning, and it’s important to understand what might be happening.

First, let’s clarify the concept of strabismus. Strabismus, commonly known as "crossed eyes" or "squint," occurs when the eyes do not properly align with each other when looking at an object. This misalignment can be constant or intermittent and can affect one or both eyes. In your case, if your left eye appears to drift outward when focusing on distant objects, it could be a form of strabismus, particularly if this misalignment is noticeable to others or if you find it difficult to maintain focus.

The fact that you mentioned having a slight difference in the size and height of your eyes (often referred to as "anisocoria" or "ptosis") could also contribute to the perception of misalignment. These anatomical differences can affect how your eyes work together, especially when focusing on objects at varying distances.

Regarding your observation of needing extra time to focus on distant objects, this could be related to a few factors. One possibility is that your eyes may be experiencing a temporary difficulty in adjusting to different focal lengths, which can happen due to fatigue or strain, especially if you have been using your eyes for prolonged periods, such as reading or using screens. This is often referred to as "accommodative fatigue," where the eye's ability to focus becomes temporarily impaired.

In terms of whether this can be corrected through eye exercises, it is possible that certain visual training techniques may help improve coordination and focus. However, the effectiveness of such exercises can vary from person to person. It’s essential to consult with an eye care professional who can assess your specific situation and determine the best course of action.
As for whether you should visit a general eye clinic or a larger hospital, it depends on the severity of your symptoms and your comfort level. A general eye clinic can perform a comprehensive eye examination, including tests for strabismus and other alignment issues. If they find any significant concerns, they may refer you to a specialist or a larger medical facility for further evaluation.

In conclusion, while your symptoms may suggest a potential issue with eye alignment, it is crucial to have a thorough examination by an eye care professional. They can provide you with a definitive diagnosis and discuss the best treatment options, which may include corrective lenses, vision therapy, or, in some cases, surgery if deemed necessary. Remember, early intervention can often lead to better outcomes, so don’t hesitate to seek professional advice.

Take care, and I hope you find the answers and relief you are looking for!
