What is the cross section of eye?
Eye Cross-section When light strikes the eye, the first part it reaches is the cornea, a dome positioned over the center of the eye. The cornea is clear and refracts, or bends, the light passing through it.
What is the physiology of the eye?
The eye is often compared to a camera. Each gathers light and then transforms that light into a “picture.” Both also have lenses to focus the incoming light. Just as a camera focuses light onto the film to create a picture, the eye focuses light onto a specialized layer of cells, called the retina, to produce an image.
What is the ora serrata?
The ora serrata is the peripheral termination of the retina and lies approximately 5 mm anterior to the equator of the eye. The ora serrata is approximately 2 mm wide and is the site of transition from the complex, multilayered neural retina to the single, nonpigmented layer of ciliary epithelium.
Which structure is commonly called the blind spot?
Blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina.
What color is the ora serrata?
teeth and bays often vary in size. serrata is seen distinctly because of a color contrast between the thin, reddish pars plana and the peripheral portion of the retina, which is thicker and grayish. Moreover, the anterior border of the ora is clearly demarcated by a narrow, serrated, pigmented band in the pars plana.
Why is the ora serrata important?
The ora serrata is the serrated junction between the choroid and the ciliary body. This junction marks the transition from the simple, non-photosensitive area of the ciliary body to the complex, multi-layered, photosensitive region of the retina. This point is the ora serrata.

What is the function of the cornea in the eye?
The cornea is clear and refracts, or bends, the light passing through it. Light then reaches the pupil and the iris. These parts of the eye are responsible for regulating the amount of light that gets through. Too much or too little light can hinder one’s vision.
What are the three types of eye cones?
There are three types of cones: one sees red, one sees green, and one sees blue. Lack of one or all of these is what causes color blindness. A lack of the green or red cones (which results in red-green color blindness) is more common than lack of blue cones or lack of any cones at all.
