because the vitreous of the eye tends to pull away from the back of the eye as we get older. sometimes it pulls too hard and pulls the retina. fluid can get behind the tears in the retina causing it to pull away such as wallpaper pulls off the wall when it gets wet.

What is the procedure to repair a detached retina?
The vitreous is a gel-like fluid which fills most of the eye. As people age, this vitreous becomes more and more liquefied. The vitreous has loose attachments to the retina, and more firm attachments to the optic nerve. At some point in a person's life, the vitreous liquefies enough to shift position in the eye. When this occurs, usually between age 50 and 70, the back edge of the vitreous will pull forward away from the retina, leading to a "vitreous detachment". This is generally a normal process, although it may happen abnormally early in cases of high nearsightedness or trauma. As the vitreous detaches, it tugs on the retina. This is perceived as a flash of light, similar to a lightning flash in the corner of the vision. It may occur especially with eye movement, since the vitreous moves in the eye. Debris pulled off of the optic nerve and retina are then seen as floaters, suspended in the vitreous above the retina. Sometimes this is described as a cobweb, a net, a string, or a fly over the vision.

What is the zonules' function?
The zonules of Zinn are rings of tiny fibrous strands inside the eyeball which connect the lens to a surrounding ring of muscular tissue, called the ciliary body. At rest, the circumferential muscle fibres in the ciliary are relaxed, and so the radial fibres in the zonules are taut. The lens is a flattened sphere, and in this resting state the zonules pull on its equator to make it more oblate (i.e. they 'flatten' it in a front-to-back direction). This focuses distant objects onto the light sensitive retina at the back of the eye.

How do you replace the brake lamps on a 1995 Ford Crown Victoria?
In the trunk, you will have to pull back the liner from the back of the trunk. Underneath there you will find about 5 large plastic wing nuts. Remove these, and then pull the lens assembly out away from the car. You will then be able to get to the bulbs.
