Why Does My Child See Things Shrink? Vision Changes - Ophthalmology

Objects appear smaller when viewed with the eyes?


Hello, Dr.
Huang; my son is 9 years old and has hyperopia.
He is currently wearing an eye patch and undergoing glasses correction.
Recently, he has frequently reported that things appear smaller when he looks at them, and this lasts for about 10 to 20 seconds before returning to normal.
This mostly occurs when he is lying down at night, but it has also happened during the day.
During these episodes, his vision alternates between looking normal and appearing smaller.
We have consulted an ophthalmologist, and the examination of his optic nerve was normal.
We are unsure of the cause of this issue; could it possibly be psychological? He has experienced this after having nightmares.
If we were to visit a hospital, what tests should be conducted? Thank you!

First of all, I apologize for the delay in response due to a network outage at our hospital.
I cannot think of any specific reasons, so it seems that your child's condition may be related to psychological factors.
I recommend consulting a psychiatrist, as it may be helpful.

Dear Parent,
Thank you for reaching out with your concerns regarding your child's vision changes. It's understandable to be worried when a child experiences unusual visual phenomena, especially when it involves their perception of size. Let's delve into the possible reasons behind your child's experience of seeing things shrink, as well as the appropriate steps to take.

Firstly, the phenomenon of seeing objects appear smaller can be attributed to several factors. One possibility is related to the visual processing in the brain. Children, especially at the age of nine, are still developing their visual perception skills. This means that their brains are learning to interpret visual information, and sometimes, this can lead to temporary distortions in how they perceive size and distance. This is particularly true when they are in a relaxed state, such as lying down, where their focus may shift and cause visual discrepancies.

Another potential cause could be related to the eye condition your child has, which is hyperopia (farsightedness). In children with hyperopia, the eye may struggle to focus on nearby objects, which can lead to visual discomfort or distortions. The use of corrective lenses, such as glasses, is essential in helping the eyes focus properly. However, if the prescription is not perfectly suited to your child's needs, it might lead to temporary visual distortions, including the perception of size changes.

Additionally, visual disturbances can sometimes be linked to fatigue or stress. If your child has been experiencing nightmares or has had a stressful day, this could contribute to visual changes. Stress can affect how the brain processes visual information, leading to temporary distortions. It's important to ensure that your child is getting adequate rest and managing stress effectively.

Regarding your question about psychological factors, while it is less common for psychological issues to manifest as visual distortions, they can occur. Anxiety, for instance, can lead to heightened awareness of bodily sensations, including visual changes. If your child is experiencing anxiety or stress, it may be worth discussing these feelings with a pediatrician or child psychologist.

In terms of medical evaluations, since you have already had an eye examination that showed normal optic nerves, it may be beneficial to consider a few additional assessments. Here are some suggestions:
1. Comprehensive Eye Exam: Ensure that your child has a thorough eye exam with an optometrist or ophthalmologist who specializes in pediatric care. They can assess the prescription for glasses and ensure that it is appropriate for your child's needs.

2. Visual Processing Evaluation: A specialist in visual processing can evaluate how your child's brain interprets visual information. This can help identify any underlying issues that may be contributing to the visual distortions.

3. Neurological Assessment: If the visual changes persist or are accompanied by other symptoms (such as headaches, dizziness, or changes in behavior), a referral to a pediatric neurologist may be warranted to rule out any neurological conditions.

4. Psychological Evaluation: If there are concerns about anxiety or stress, a consultation with a child psychologist can provide insights and coping strategies for your child.

In conclusion, while it is likely that your child's experience of seeing things shrink is related to their developing vision and possibly their emotional state, it is essential to continue monitoring the situation. If the symptoms persist or worsen, seeking further evaluation from specialists will be crucial in ensuring your child's visual health and overall well-being.
Please feel free to reach out if you have any further questions or concerns.
