... the device can be useful in these cases. This is because corneal edema typically results in a mild underestimation of IOP—by only a few points. “If the true IOP is 19, GAT might measure 15 to 17. But that difference is not clinically significant,” he said.  High astigmatism. Dr. Berdahl noted that t ...

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.
