Gene study sheds light on causes of childhood sight loss 18/05/2017
... A genetic mutation that contributes to sight loss in children has been identified by scientists. The mutation was identified in patients with a disease known as ocular coloboma, which causes part of the eye to be missing at birth. The findings shed light on its causes and help to explain how genes c ...

Human eye
The human eye is an organ that reacts to light and has several purposes. As a sense organ, the mammalian eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors.Similar to the eyes of other mammals, the human eye's non-image-forming photosensitive ganglion cells in the retina receive light signals which affect adjustment of the size of the pupil, regulation and suppression of the hormone melatonin and entrainment of the body clock.
