Vision problems


Hello, my child is four years old and does not show any abnormalities when looking at objects or watching TV from a distance of about 5 meters.
He can see the corners of the screen.
However, an examination revealed that he has hyperopia of +1.00 diopters and astigmatism of -2.50 in the right eye, and hyperopia of +1.25 diopters and astigmatism of -2.75 in the left eye.
After dilation, his visual acuity was 0.5.

1.
Is it possible that there is an error in these examination results?
2.
Does a hyperopia of +1.00 with a visual acuity of only 0.5 indicate that his near vision is also 0.5?
3.
The report suggests that the only treatment is to wear glasses and return for a follow-up in three months.
Why did the doctor not recommend patching or using dilating drops at this time? Are these necessary?
4.
If my child's vision improves to 0.8, can he stop wearing glasses, or should he continue wearing them until he is 8 years old or indefinitely? Thank you.

Hello, Ms.
Li: A vision of 0.5 indicates poor eyesight, meaning the distance vision is 0.5.
There should not be any significant error.
He has hyperopic astigmatism, so there is no need to use a dilating agent, and if both eyes are affected, there is no need to cover one eye.
As long as he wears the correct glasses and has regular follow-ups, that should suffice.
If wearing glasses improves vision to 0.8 but it becomes unclear without them, he should continue to wear them to prevent deterioration.
Better vision can only be achieved while wearing glasses, and he should keep wearing them until his vision development is complete.
Whether he can stop wearing glasses later will depend on the condition of his vision.
The ophthalmology department at Puzi Hospital in Taiwan is open: Monday, Tuesday, Thursday, and Friday from 8:00 AM to 12:00 PM, and Wednesday from 2:00 PM to 4:30 PM.
Online responses are for reference only; it is necessary to seek medical attention at a healthcare facility if needed.
I hope to have the opportunity to serve you.

Hello! It's great that you're seeking information about your child's vision. Understanding the complexities of children's eye health is crucial, especially at such a young age. Let's address your concerns one by one.

1. Possibility of Measurement Error: It's not uncommon for vision tests to have some variability, especially in young children who may not fully cooperate during the examination. Factors such as fatigue, distractions, or even the testing environment can affect the results. However, if the measurements were taken under standard conditions and the eye care professional used appropriate techniques, the results are likely accurate. If you have concerns about the accuracy of the results, it may be worth seeking a second opinion from another eye care professional.

2. Understanding the Results: The results indicate that your child has hyperopia (farsightedness) and astigmatism. A hyperopia of +1.0 diopters means that the eye has difficulty focusing on nearby objects, which could explain why the visual acuity is only 0.5. This does not necessarily mean that the vision for distant objects is perfect; it indicates that the eye may struggle to focus on both near and far objects adequately. The visual acuity of 0.5 suggests that your child may have difficulty seeing clearly at a distance, which is consistent with the degree of hyperopia and astigmatism noted.

3. Treatment Recommendations: The decision to prescribe glasses, perform patching (occlusion therapy), or use atropine drops depends on various factors, including the severity of the refractive error, the presence of amblyopia (lazy eye), and the child's overall visual development. In cases of mild hyperopia and astigmatism, especially if the child is not showing signs of significant visual impairment or amblyopia, the doctor may opt to monitor the situation with glasses as the first step. Patching or atropine drops are typically reserved for more severe cases of amblyopia or when the child is not responding adequately to glasses alone.

4. Long-term Use of Glasses: Whether your child can eventually stop wearing glasses depends on several factors, including the degree of hyperopia, the child's age, and how their vision develops over time. Many children with mild to moderate hyperopia can achieve normal vision with corrective lenses, and some may outgrow the need for glasses as their eyes develop. However, it is essential to follow up regularly with your eye care provider to monitor changes in vision and determine the appropriate course of action. If your child's vision improves to 0.8 or better with glasses, it may be possible to reduce the frequency of wearing them, but this should be guided by your eye care professional.

In conclusion, regular eye examinations are crucial for monitoring your child's vision, especially given the findings of hyperopia and astigmatism. Early intervention can help prevent potential issues such as amblyopia. If you have any lingering concerns or if your child shows signs of visual discomfort, don't hesitate to discuss these with your eye care provider. They can provide tailored advice based on your child's specific needs and circumstances. Thank you for your questions, and I wish you and your child the best in maintaining healthy vision!
