Brushfield spots are small, white or grayish spots seen on the periphery of the iris, often associated with Down syndrome. These tiny specks, named after British physician Thomas Brushfield, can be a key indicator for medical professionals. But what exactly are they? Brushfield spots are clusters of connective tissue that appear as part of the iris's natural structure. While they are more common in individuals with Down syndrome, they can occasionally be found in people without the condition. Understanding these spots can provide valuable insights into eye health and genetic conditions. Ready to learn more? Here are 40 intriguing facts about Brushfield spots that will deepen your understanding of this unique ocular feature.
Key Takeaways:
- Brushfield spots are small, white or grayish spots on the iris, often linked to Down syndrome but can also appear in individuals without the condition. They are more common in people with lighter-colored eyes and are usually harmless.
