Amblyopia in Children


A 5-year-old child underwent a vision examination and was found to have a visual acuity of 0.8 in both eyes, along with hyperopia of +2.75 diopters and astigmatism of -1.00 diopters.
Two general ophthalmologists diagnosed the child with amblyopia, although one mentioned that the visual acuity of 0.8 is on the borderline of normal.
They recommended corrective lenses, stating that without correction, the vision would remain the same—neither improving nor worsening.
Is this accurate? Subsequently, a pediatric ophthalmologist assessed the child and found similar measurements but considered them to be within normal limits, suggesting only regular follow-up.
Now, I am uncertain about the best course of action moving forward.

Hello, it is not surprising to have different opinions due to being on the fringe.
In my view, if the data is accurate, I still recommend corrective lenses as a precaution.
Wishing you safety and health.

Amblyopia, commonly referred to as "lazy eye," is a condition where one eye fails to achieve normal visual acuity, despite the presence of a structural eye problem. In your case, your 5-year-old child has a vision measurement of 0.8 in both eyes, along with hyperopia (farsightedness) of +275 and astigmatism of +100. The conflicting opinions from different eye care professionals can understandably lead to confusion regarding the best course of action.

Firstly, it's important to clarify that a visual acuity of 0.8 (which is equivalent to 20/25 in the United States) is generally considered acceptable for a child. However, the presence of hyperopia and astigmatism can complicate the situation. Hyperopia can lead to difficulties in focusing on near objects, which may contribute to visual discomfort or fatigue, especially in a learning environment where close-up work is common. Astigmatism can cause blurred vision at all distances, which may also affect the child's overall visual experience.

The recommendation to correct the vision with glasses is a common approach, especially in cases of significant refractive errors like those you described. Corrective lenses can help ensure that the child sees as clearly as possible, which is crucial for proper visual development. If left uncorrected, the child may struggle with visual tasks, potentially leading to further amblyopia or other visual issues.

Regarding the opinions of the eye doctors, it is not uncommon for different practitioners to have varying perspectives based on their clinical experiences and interpretations of the data. The first doctor’s suggestion to prescribe glasses for correction aligns with the standard practice of addressing refractive errors to prevent amblyopia from worsening. On the other hand, the pediatric ophthalmologist's view that the vision is "normal" and only requires monitoring may reflect a more conservative approach, particularly if the child is functioning well in daily activities and does not exhibit signs of significant visual impairment.

In terms of next steps, here are some recommendations:
1. Follow-Up with an Eye Care Professional: Since you have already seen multiple doctors, consider returning to the pediatric ophthalmologist for a comprehensive evaluation. They can assess the child’s visual development and determine if corrective lenses are necessary.

2. Consider Glasses: If the first eye doctor recommended glasses, it may be beneficial to try them. Monitor how your child responds to wearing glasses, especially during activities that require near vision, such as reading or drawing.

3. Regular Eye Exams: Schedule regular follow-up appointments to monitor the child’s vision. This is particularly important in early childhood, as vision can change rapidly during this developmental stage.

4. Visual Therapy: If amblyopia is diagnosed, visual therapy may be recommended. This can include exercises aimed at improving the coordination and strength of the weaker eye.

5. Educational Support: If your child is experiencing difficulties in school or with visual tasks, consider discussing this with their teacher. Accommodations may be necessary to support their learning.

6. Parental Observation: Keep an eye on any changes in your child’s behavior regarding visual tasks. If they seem to struggle more than usual or express discomfort, it’s essential to communicate this to their eye care provider.

In conclusion, while your child's vision of 0.8 is on the borderline of normal, the presence of hyperopia and astigmatism warrants careful consideration and possibly corrective lenses. Regular monitoring and follow-up with an eye care professional are crucial to ensure optimal visual development and to address any emerging issues promptly.
