Retinal detachment is an eye disorder which can cause permanent blindness if not treated quickly.
It happens when your retina peels away from the back of your eye, like wallpaper peeling away from a wall.
Retina contains light-sensitive tissues. These tissues work like the film in a camera.
When light falls on these tissues, they generate nerve impulses and send them to the brain which assimilates them and then interprets the information into a image.
In short, without the retina, no image signal can be sent to the brain and blindness occurs.
Normally, a healthy retina is securely attached to the back of the eye.
Occasionally, eye injury, trauma to the head, posterior vitreous detachment (PVD) or overstretching of the retina due to elongated eyeball (severe nearsightedness) may cause a tear or hole in the retina.
When the vitreous humor enters the opening, it lifts the retina off and creates separation between the retina and the choroid.
Thus causing the retina to slowly peel away from the choroid, similar to air bubbles beneath wallpaper.
