Question
Dear Doctor: I recently noticed that my 9-month-old son has one eye's pupil positioned closer to the center of his nose compared to the other eye.
Will this affect his vision in the future?

Hello, Miss: Regarding your younger son's condition, it is important to differentiate whether there is a problem with strabismus (esotropia).
The presence of strabismus can be easily assessed by using a flashlight to project light and observing the reflection point in your son's eyes.
If the reflection point is located at the center of the pupil, congratulations, your son is normal.
However, your son's situation may appear as esotropia due to the wider distance between the inner corners of his eyes in infants, which can obscure the white part of the eyes on the inner side.
Therefore, I recommend conducting a preliminary examination.
If you still have concerns, it would be best to take your son to the hospital for further evaluation.
If you have any related questions, feel free to visit the Ophthalmology Department at the Municipal United Hospital or contact your child's attending physician.
Wishing you good health.
Dr.

More Info
The alignment of your baby's eyes, particularly if one eye appears to be more inwardly positioned than the other, can indeed have implications for his vision as he grows. This condition is often referred to as "strabismus," which can manifest as either esotropia (inward turning) or exotropia (outward turning). In infants, it is not uncommon for eye alignment to appear imperfect due to the developmental nature of their visual system. However, persistent misalignment can lead to several visual issues.
When one eye is misaligned, the brain may receive two different images, which can cause confusion. To compensate, the brain may suppress the image from the misaligned eye, leading to a condition known as amblyopia or "lazy eye." This can result in reduced vision in the affected eye if not addressed early. The critical period for treating amblyopia is during the early years of life, typically before the age of 7, when the visual system is still developing.
To assess whether your son has strabismus, a simple test can be performed at home. Shine a flashlight at your child's eyes and observe the reflection of the light on the corneas. If the reflections are not symmetrical, it may indicate an alignment issue. However, a definitive diagnosis should be made by a pediatric ophthalmologist.
If your son does have strabismus, treatment options may include corrective glasses, patching the stronger eye to encourage use of the weaker eye, or in some cases, surgery to realign the eyes. Early intervention is crucial, as it can significantly improve the chances of normal vision development.
In terms of your concern about whether the misalignment will affect his vision later, it is essential to monitor the situation closely. If the misalignment persists, it could lead to long-term visual problems. Therefore, it is advisable to consult with a pediatric ophthalmologist for a comprehensive evaluation. They can provide guidance on the best course of action and whether any treatment is necessary.
In summary, while some degree of eye misalignment can be normal in infants, persistent or significant misalignment should be evaluated by a specialist. Early detection and treatment are key to preventing potential vision problems later in life. Regular check-ups and monitoring will help ensure that any issues are addressed promptly, allowing your child to develop healthy vision.
