Seeing white spots in the dark?


Hello, my child is currently 8 years old and sees moving white spots in dim light.
However, both the school vision screening and the ophthalmologist examination indicated that there are no issues, and there is no myopia; their vision is generally fine.
Should I take them to a larger hospital for further examination?

Seeing moving white spots in low light can be concerning, especially for a child. While the initial eye examinations have indicated that there are no significant issues, it is essential to consider a few factors before deciding whether to seek further evaluation at a larger hospital.

Firstly, the phenomenon of seeing moving white spots, particularly in low light, could be related to a benign condition known as "visual snow" or "entoptic phenomena." These are often harmless and can occur when the eye perceives internal structures or particles within the vitreous humor, which is the gel-like substance that fills the eye. In children, this can sometimes be more pronounced due to their developing visual systems.

However, it is crucial to rule out any potential underlying issues. Although the initial assessments have shown no signs of refractive errors or other significant problems, there are a few reasons why you might consider a follow-up examination:
1. Persistence of Symptoms: If the child continues to see these moving white spots, especially if the frequency or intensity of the phenomenon increases, it would be prudent to seek further evaluation. Changes in visual perception can sometimes indicate underlying conditions that may not be immediately apparent during a standard eye exam.

2. Associated Symptoms: Pay attention to any additional symptoms that may accompany the visual disturbances. For instance, if the child experiences headaches, changes in behavior, or other visual disturbances (like flashes of light or a sudden increase in floaters), these could warrant a more thorough investigation.

3. Developmental Considerations: At the age of 8, a child's visual system is still developing. Any unusual visual experiences should be monitored closely. If there are concerns about how these experiences might affect the child's learning or daily activities, a more comprehensive evaluation could provide peace of mind.

4. Specialized Testing: Larger hospitals or specialized eye clinics may have access to advanced diagnostic tools that can provide a more detailed assessment of the eye's health. This could include imaging studies or tests that evaluate the retina and optic nerve more thoroughly.

5. Consultation with a Pediatric Ophthalmologist: If you decide to seek further evaluation, consider consulting a pediatric ophthalmologist. These specialists are trained to address the unique visual needs of children and can provide a more tailored approach to any concerns.

In conclusion, while the initial assessments indicate that there are no significant issues, it is always better to err on the side of caution when it comes to a child's vision. If the moving white spots persist or if you have any concerns about the child's visual health, seeking a second opinion or further evaluation at a larger hospital would be a wise decision. Early detection and intervention can be crucial in addressing any potential issues, ensuring that the child maintains optimal visual health as they grow.
