When a baby’s eyes grow, what to expect from them
Posted May 29, 2018 04:05:22 As newborns are born with their eyes, they have their own unique set of visual systems.
They will not just have the same eye color as their mothers, but they also have different pupil dilation, pupil dinging and iris thickness.
But how does the baby know when to expect different colors?
A new study suggests a baby could be born with a “non-specific” set of features that may be used as an indication of eye development.
As the baby grows up, they might also have pupils that are not as well developed as those of their mothers.
A new study in the journal Developmental Science suggests that babies with a non-specific set of eye features are more likely to have pupils less developed than those with a specific set of eyes.
“A child’s eyes are a highly dynamic system,” Dr Sarah Hulme, from the University of Sydney’s Centre for Brain and Cognitive Development, said.
“The human eye is constantly changing with each passing day and these developmental changes are a part of the way we are evolving.”
Hulme’s team has been studying the development of the eye since it was first discovered by the Spanish surgeon Dr Pedro de Olmos in the 18th century.
Using genetic material, they found that in contrast to normal children, infants with certain eye features have a higher rate of developing vision problems and vision loss.
As the baby develops, their pupils become smaller and thinner.
These pupils become more developed and then, as the child ages, they become smaller again and thinner again.
The researchers found that a child’s pupils were most similar to those of other infants at the age of 5 or 6 months.
But when they looked at the pupils of babies at 10 to 12 months of age, they discovered that they were not the same as those that were developing in their parents’ eyes.
They found that pupils in the parents’ pupils were different from the pupils in their babies.
This was not the case in the babies with non-related eye features.
They had pupils that were much less developed and they were less likely to develop eye disease.
When Dr Hulmes and her team looked at a different group of babies, they were able to look at the pupil dangles and pupils of the babies that had non-associated eye features and those that had a specific eye feature.
These were babies whose pupils had developed more slowly than those of the non-affected infants.
Dr Hulness said the research had found that, as babies aged, they may have pupils with more developed pupils and that this was a more significant predictor of developing visual problems.
She said this type of development was not unique to infants, but that it was something that was observed in the human brain and might be related to different neural pathways in infants than it was in humans.
Children’s eyes may be a ‘non-differential system’, she said.
“The brain is a non–differential, non–independent, non-modifiable system.”
It’s not just about the eye, but also the other visual systems.
“The study found that babies who had more eyes in the body with a particular set of vision features, such as having smaller pupils, were less affected by eye disease later in life than those whose pupils were less developed.
Other researchers were less sure.
Although they had been looking at the brain, they had also been studying infants.
Dr Hultes group, which is based in Melbourne, looked at data from more than 1,000 babies born between 1994 and 2001.
They found that some babies with more eyes at birth had less vision problems than others.
And the results were consistent across the different studies.
For example, babies who were born with larger pupils, like those with more irises, had more problems with vision at three and five years of age.
While there were no studies looking at whether babies who have more eyes have more problems later in their lives, Dr Hulsme said there was “a clear relationship” between the amount of eyes and the amount that developed problems later.
What do other researchers say?
Dr John Baskin, from University College London, said babies with specific eye features were more likely than babies with the nonrelated eye set to have trouble with vision later in childhood.
He said: “We know from research on humans that babies can be born without a specific type of eye and this might be a reason why these babies might develop problems with sight later in development.”
Dr Baskins team looked into the development in the brains of babies with different types of eyes, which they found to be linked to a type of brain development known as visual discrimination.
According to this model, a brain’s “general function” is to make the brain use different inputs to determine which input to send to the brain’s neurons.
