Okay, I know I'm supposed to be able to answer questions here,
but a friend who teaches grades 7 & 8 general science wants to
know if the human eyeball is fully grown at birth. I checked
my references, which are rather limited when it comes to human
physiology, and found nothing. Can anyone help?
The eye will still develop in size, pigmentation, and neurologically
but I don't have the details here at hand. A kitten is born with eyes
even more immature than human babies. Besides having sealed eyes that take
about a week to open, they have retinas that a avascularized and need
to undergo neovascularization to properly nourish and oxygenate the tissue.
We have used the kitten to study retinopathy of prematurity, a condition
caused in part by increased inspired oxygen. The kitten is also used in the
study of diabetic retinopathy which a I think is the leading cause of
blindness in the US. Look up publications by Dale Phelps, MD.
