A seven-week-old human baby following a kinetic object. Infant vision concerns the development of visual ability in human infants from birth through the first years of life. The aspects of human vision which develop following birth include visual acuity, tracking, color perception, depth perception, and object recognition.
Coloboma in the right eye of a 10-month-old child. There are two categories in which the signs of congenital blindness can be classified. The first category pertains to consistently poor vision, such as not displaying preferential looking when presented with high-contrast visual stimuli. [6]
Babies who are born prematurely (formally defined as 37 weeks of gestational age or earlier) are at higher risk of developing retinopathy of prematurity. The earlier a preterm baby is born, the greater the baby's risk of developing ROP. Blood vessels in the eye typically finish development by the time of birth.
Many babies are born with blue eyes, and then their eyes change color as their genes continue to develop. Hair color is the same way, sometimes, babies are born with very light colored hair that ...
Infants are born with minimal eyesight, compact and fleshy bodies, and "fresh" features (thinner skin, small noses and ears, and scarce hair if any). However, this stage is only brief amongst primates; their offspring soon develop stronger bones, grow in spurts, and quickly mature in features.
Statements that certain species of mammals are "born blind" refers to them being born with their eyes closed and their eyelids fused together; the eyes open later. One example is the rabbit . In humans, the eyelids are fused for a while before birth, but open again before the normal birth time; however, very premature babies are sometimes born ...
Several layers such as the neural tube, neural crest, surface ectoderm, and mesoderm contribute to the development of the eye. [2] [3] [4] Eye development is initiated by the master control gene PAX6, a homeobox gene with known homologues in humans (aniridia), mice (small eye), and Drosophila (eyeless). The PAX6 gene locus is a transcription ...
