Previously, treating damaged eyes with epidermal growth factor induced Muller glia proliferation in the mouse eye, but neuron generation only occurred with concurrent overexpression of Ascl1. [9] More recently, robust Muller glia proliferation and subsequent neuronal differentiation has been seen using the alpha 7 nAChR agonist, PNU-282987. [ 10 ]

A distant object is defined as an object located beyond 6 meters (20 feet) from the eye. [citation needed] When an object is located close to the eye, the rays of light from this object no longer approach the eye parallel to each other. Consequently, the eye must increase its refractive power to bring those rays of light together on the retina.
Here are the 12 best mascaras for sensitive eyes, according to editor testing and two ophthalmologists. Shop our picks for volume, length, definition, and more.
Uveitis is a fancy word for eye diseases that cause redness and inflammation in the eye, usually in the middle layer, and Dr. Bert says it's another reason for floaters. There are several types ...
Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue.
The eye is essentially a derivative of the ectoderm from the somatic ectoderm and neural tube, with a succession of inductions by the chordamesoderm. Chordamesoderm induces the anterior portion of the neural tube to form the precursors of the synapomorphic tripartite brain of vertebrates, and it will form a bulge called the diencephalon.
The eye with overactive accommodation may still require too much minus sphere in order to balance the red and green. Cycloplegia may be necessary. The duochrome test is not used with patients whose visual acuity is worse than 20/30 (6/9), because the 0.50 D difference between the two sides is too small to distinguish.
